Description
Th~~''~E: ADUEDUS ODDFt CONTROL CDMPO~I~1~]
FIET~~ 0f THE LION
Tl2e present invention is directed to an aqueous odor control composition for controlling odor associated wi~,h deposits on surfaces, particularly spills of organic material on surfaces, more particularly on carpet.
upholstery or other fibrous material.
1D BACKGROUND bF THE INVEN'fZON
There are many instances where, owing to deposits of orgtiniC ma'texial ran surfaces, offensive odors can arise through tkle presence of the organic material or its decomps~sition. For example, much household waste 15 contains orgar~ie material, which upon decampasi.tion can give xise to offensive odors. This is partiCu~.arljr true where the household waste must be stored for a period of 'time prior to its disposal. Similarly, many fibrous materials utilized in household appliGation.S are a~.so 20 susceptible to soiling bx organic based material, wkx~.ch can give rise fi.o offensive odors. These fibrous materials include carpet. upY~,al,stery, battiri.r~ used for mattresses, pillow aa~i pad. as well as other relatively porous surfaces encountered in the household or 25 commercial environment.
~lariy fibrous materials, such as acrylic, polyester, polypropylene and wool, and particularly nylbxx used in th,e maxzufacture of upholsterx, carpets, batting 34 and hvusehpld fabrics may be susceptihlE to staining especially from the many food dyes used ~,x~. hever$ges and other foods as well as fx~an rather chemicals from many sources. Nylon aa,rpet fibers are often treated with stain blockers such its a sulfonated phenol foxma~.dehyde 35 cvndensate polymer, a sulfonated naphthol formaldehyde oondensate polymer, a kaydrrlyzed vinyl aromatic malefic anhydride polymer, certain iluorochemicals or combinations thereof. The stain blackers net to prevent or reduce the ability of organic dyed, particularly acid dye Cdlorants from chemically reacting wzth and bondixsg to th.e nylon. Z'he fibrQUS material, ~sp,~cia3.ly carpet fibers are also commonly coatiø. with a fluorachem~.oa1 5 anti-soiling agant to imgrove the anti-staining or anti-soiling characteristics of the carpet surface. The anti-soiling fluorochemiCals reduce the t$nca,erlcy of soil to adhere t4 the fiber making the clean up of any spills ør soil on the carpet easier. The fluoroch~nicals also 10 reduce fiber wetability, making for easy cl~aar~, up of licauid.spills through a simple process of blotting the spill. Examp~,eS of Such fluorochemiCdls and other stain resistant chemicals are given, fQr example, ~in U.S.
Pater~t rxutnberc ~, 580, 212 and 4, 925, 707, the disclo~~,,res 15 of which e.xe incox~orated herein. by reference. The use of the stain blackers and fluorocl~.emical~ may not provide c4xttplete stain resistarxce to the carpet, as some materials may still pez»strate the nylon. fibers or react with the fibers, especially if left ire contact with the 20 carpet for extended periods of time. This may be especially ~tue Where the carpefi is exposed to conditions such as direct Sunlight or other 17V sources or high traffic areas, as these conditions may cause the effectiveness of the flucrochemical and stain Mocker 25 coatings to be diminished.
In addition, espdcially in residentie.l locations, the possibility of deposits of organic matter such as feces or urine from babves and pets can result in not 30 only soiling of fibrous and other porous materials such as carpets and bedding but also a lirlger~,ra,g odor ,and may;
in extreme cases, require the replacement of the soiled object. rn the past, various ch~mic~al compounds ha,~cre been prol5osed tb aid in removing odor in a cleaning 35 process. Such chemicals generally act as ado inhibiting 3~er~ts such as U.S. Patent No. 4,996,672 which describes the use of biguanidine polymer compositions as odor inhibiting agents. However, even in Chase cases urhexe the d~posit is cleaned up and odor inhibiting agents utilized. the odor from such deposits may remain in the sailed objects and may become apparent as tk~e effect df the odor masking agents wear off.
deposits of various materials on CaYpet 3xid other fibrous materials may also give riss~ to athcr concerns.
Many of the deposit materials. are capable of supporting bacterial growth, especially iri tkie case of feces which car~.ta~.,ns many bacteria. Some of tk~~ bac'teria that may grow, as a result of a deposit, may ha~cre the potential of causing disease in persons exposed to them, such as mold and mildew. Cax'pet axed ot~7.8x fibrous material are also known, to Gantain a number of naturally occurring bacteria and other organisms. Some of th~s~ bacteria. may ~.Izemselves dive rise to odor duo to ~.r'~.c4mplete digestion of organic material. There have. been attempts to reduce the prosence and number of bacteraa ~Sresetlt in carpet by utilizing varis~us anti-microbial s,gex~ts suG~ as described ~,ri U.S- Patent Nos. 4,110,504 and 5,024,840. These agents are applied to ta.rpet in a manner similar to the way stain blackers axe applied to carpet. The use of Finti--mierobials, while reducing the number of bacteria associated with carpet, may raise other concerns such as the impact Qx~ k~.umary. and animal health and the potential that some of the bacteria may become resistant to etfeCtS
of the anti-microbialS.
Many bacterial and fungal genera are known for exec in odor control due td their capability for producZag enzymes that dxe capable of breaking down organic material. Such bacteria are particularly useful where the orgazxic material, if allowed to remain, will g~.ve rise to malodors. Several such bacterial and fungal genera such ass Bacillus, Lactobacillus, Enterobacter.
Stxe~tococcus, Rt1i2o1~Lt8, Nitrosornonas, Nitrobaetier, ~seudomorias, ~,~caliuens and, K~.ebsi~l.la, ,~mbri.g Dthers, are known for u8e: iri such applications ~nrith Bacillus sp.

The bacterial preparations are used. to deodorize a deposit by application directly on the deposit. Once the deposit is deodoxiaad. t'he bacteria are depleted from the site or 20 disposed of alonc3 with the deodorized material. Ire the event of a new deposit on the carpet, the treatment must be repeated.

is DETAILED DESCRIPTION OF THE PREFERREDEMBQDIL~ENT
The present invention is directed in one aspect to a method of controlling odor associated with deposits, ~0 particularly spills, of organic material which can cause odors on surfaces, particularly carpet or other fibrous materials. The present invention is also directed to the ac~xeous compositions useful for treating a~xrfaces.
particularly carpet or other fibrous material to make 25 them capabls of Gor~trollirtg odor as well as to the surfaces. xx~ add~.t~,ori to aorit.rclling odor, the compositions may also aid in reducing the staining effects of organic mater~.a~..
30 Many 7,~acterial genera are. known to produce enzymes fat aWe. c8p2~1~1A of bro8,kixeg ~3owrs c,5rgariio mc~lt~rz.al. Such baatsria arc partiauxs,r~.y useful where this orgaaic material, if allowed to remain, will give rise to malodors. several such bacterial genera such as 35 Bacillus, Lactobacillus, Enterobacter, Strentococcus, Nitrosomana~, Nierobacter, Pseudc~mor~.as, A~.cal~aems axed Klebsiella amongst others are Jmown for use in such applications, with Hacillus and Lactobacillus sp. being the mast prevalent in use in various application .
Strains of bacteria from any of the above noted gen$ra are useful in practicing the present invention.
Preferably, the bacterial preparation fQx use in the present invention is one or more strains of Bacillus pr Lactobacillus, pre preferably, the strains of bacteria far use in the present invention are selected, from ,~cillus licheniformis, Bacillus pasteurii, Bacillus laavolacticus, Haci~~us meaaterium and Bacillus amvlolicruefaciens. Each of these species has characteristics that make them most effective against particular types of organic materials. All of these species are capable of enhanced anaerobic and aerobic growth. Bacillus ~$steurii is known for superiar lipase production, while Hacillus laevolacticus has a very fast germination cycle. Bacillus amvloliauefaeiena is high in production of protease enzymes.
The selection of the strains of baGberia for use ~0 is the present invention may depend upon many factors.
One rush factor is the nature of the organic material most commanly expected for the particular applieatipn, For exan~.pl~, in a commercial application, the mast commonly expected deposits would be soil tracked in from out-of-doors, beverages such as coffee, tea, Qther food and the like, especially in a restaurant environment, and pQSSibly, inks~or Goners for printers sad otrier office equipment. Many of these materials are high in fatty components so the bacterial preparation may be QnhanCed for strains having high activity against such materials.
Qne example of such a bacteria is Hs~~llus pasteurii known for superior lipase production. zn a residential environment, the nature of the $eposits may differ with out-of-doors soils. Beverages, food anc3 urine and feces from pets and children being most commonly enoauntered.
Depending upon the nature of the deposited material, the preparation may be selected t4 Gbrit~i~ strains having enhanced activity against rush materials, ~yQthex factor _ 7 that may affect the nature of the deposit is the geogxaph~.ca~, location o~ the suxface being treated. This factor would especially relate to the nature of deposits of out-of-doors sail and to the nature of food deposits.
5 Different regiana are known to have different soil types and different regions may also have differences in the foods commonly consuz~ed due to cultural and environmental factors_ In addition, the temperature of the carpet to be treated will ix~,fluextoe the activity o~ the bacteria.
10 Depending on the strain selected the bacteria will tend to exhibit enhancec'i activity at higher temperatures. At lower ambient temperatures, more active strains xna.y be desired.
15 ~~,e bacterial preparation will typically comprise one or more strains selected from the genera and Species described above: ~nlhen utilizing a mixture of more than one strain, each of the individual strains may comprise between 3~ and 97~ of the total of the bacteria present 2Q in the preparation. Depending upon the bacteria, these percentages are based ost the total cell aumk~er or CrJlol'~y farming units or the total mass of tk~~ bacterial preparation. For the Bacillus sp. the percer.~tages are based on total Cell txu~nber. Hxe~~xably, each of the 25 strains is preset7,t ire sufficient numbers t.o make up 1p$
to 70~ of the total bacteria in the preparation. When mixtures of more tha.~x two strairm are employed. eech of the strains is most pr~afera?~ly praserxt irA az~ tamourat a~
from 20~ to 40~ of the total bacteria in the preparat~.or~.
30 partiCUlarly preferred preparations far general use in almost all applications are as follaras:

Bacillus nasteurii, sacillus laevol~cticus and Bacillus 10 amYloliQUefaciens and combinations thereof are provided in a state in which the compasitiarf may be applied to d surface, such as carpet fiber or other fibrous material.
The effective amount is a sufficient number of bacteria to provide a relativa7.y uniform coverage of the syxrfe.ce 15 exposed to a deposit of as odor ca~.siz~g oxganic ms.teri~l.
The bacteria will then undergo rapid growth and consume the odor causirsg matex~~.a~.. The factors that Geri affect the number of bacteria to $e used relate in most part to the nature of the surface to be protested. For carpet, 20 such factors 3xaolude the nature or the fiber in terms of the material, a.g. zxylOn or pplypropylene and the like, the characteristics of the yarn in the terms of the denier and number of filaments and the Gharacteristic~5 c~f the fiber in terms of the number of yarns and the twist.
25 These factors relate to the nature of the carpet in terms of the weight (oz) or (g) and height of the pile. All s~f these factors will affect the ambunt of e.5cpas~d surfaoe of the fibers that m~,gY~t be covered by the bacterial p~el7~x'd:~a.8ri.. lPor mamt applications on carpet, between 30 about 106 and 10$ cells per ml of the compositior~. is preferred.
The compositions are provided as a preparation of a suspensions of the kl~acillus species. oxie or maze enzymes 35- and a non-residual surfactant in a suitable aqueous carrier, such as distilled water, tap water, a saline solution or other such aqueous solutions.
The bacteria and particularly Bac,~llus species are provided as dormant cells. The term "dormant cells" is intended to encompass cells which are in a state which are reqv.ired to be activated before they can undergo 5 growth. One example flf a dormant Cell is a sporulated farm of the bactexia where the spores must undergo activation and ger~tination before growth of the bacteria can occur.
10 $y providing the bacteria iri a dormant or sporulated form, the bacteria are protected from environmental factors which may prove detrimental to active bacterial oells. These envirox~mental factors may iriGlude exposure to heat, chemical agents, axxd UV
15 radiation from sunlight &s well as the exposure to air for those strains that may be predominantly anaerobic.
The sporulated or dormant strains of bacteria become activated and undergo germination in response to 20 being exposed to organic material including organic material that can cause odors. The factors that promote the activation of the dormant Qx sparulated bacteria include the moisture and various organic compounds present in the deposit o~ organic material. Once 25 activated, the bacteria undergo growth and replication, consuming the organic material in the deppsit until the material is depleted.
The bacterial preparation tttay be provided as a 30 concentrate to be diluted with the other ingredients.
The concentrate may include other agents far improving viability of the bacterial preparation. The cpncCntrate preferably contains between x0 arid 20 times the number of cells or spores per ml of the final compQSitian.
35 Typically, the concentrate contains about 109 cells per ml. The concentrate ie diluted with water or other agueous carrier and the other ingredients to produce the _ 1~ _ composition which is directly applied to installed surfaces, for example, installed carpet.
The composition also includes other agents namely one or mare enzymes, and a non-residual surfactant in addition to the ~aacteria spore bland. The enzymes typically employad in the composition are one or more 3ipase or protease enzymes, particularly amylase. The non-residual surfactant is one which does not leave an 10 appreciable residue upon drying. The nature of the surfactaxxt will be selected based upon the non-residual property. Particularly preferred surfactants are the sulfosuccinate anionic surfactants, more particularly the sodium dialkyl sulfosuccinates and most particularly 15 sodium dihexyl sulfosuccinates such as COLALJET MA-80 available from The T~i,orn~.ey Company, Wilmington, DE.
The odor controlling bacterial composition of the present invention may be provided with other ingredients 20 depending upon tb,e apgl~.c~,tiQx~ or suxface to be treated, such as masking agents, anti-Foaming agents, or foaming agents. The masking agents are gansrally fragrances such as vanilla or trash scent t.v zs~~.ti.al3.y mask t'~ odox associated with the material on the aaxpet. The az~ti-25 foaming agent far reducing surface terssion for reduced-absorbent surfaces may be arry commonly utilized anti-foaming agent which would be suitable for the surface to be treated. One exampla of suckr an ar~.ti-foaming agexxt is a sil.iGQnc bas~od anti-foaming ag~rit, Which m$y $e 30 utilized in compositions utilized. for txeating reduced absorbent surfaces, such a,s hard surfaces. Mme ar~ti-foaming agent may also be used in compQSi~ipns Wl~~,ch are utilized in a spray bottle for direct application by the consumer, particularly fQr carpet ox oth~rr fibrous 35 material.
Another additional ingredient which may be utili2ed iri the cOmpbSition depending upon the ~~ 11 -alapliaa~tian is a foaming agent far producing a foam ,aampasition for treating relatively absorbent surfaces, S~xCb as ad.xptt. . This foaming agent is preferably a lauryl sulphate, rrtpre preferably an ammonium lauryl 5 sulphate or sodium lauryl sulphate, most preferably sadstlm ldLtryl Sulphate. the foaming agent is utilized to produce a composition which can be applied to the surfaces of higher absorbency to allow the eompositian to he worked into the surface. This may be of particular 10 use for treating carpet. The additional ingredients would be utilized in the comgosxtions at the usually employed Cancentrations~ generally 5 percent by weight or less based upon the total weight of the compQsit,ian.
15 For treatmerxt of most surfaces by sprayir~g, the a~xu~aov.s odor controlling laacterial cQn~posit~,an Qf the present invention are preferably formulated to have the following cozapo~it~.or~:

When applying the composition to wn insta3.led carpet, it is not essential, but preferred t#aac t'h~s cQmpQSition be applied c~.c~rQUghly and evenly throughout the length of the pzle, especially reaching doom to the base of the ,pile til3er. Tfais is 20 generally achieved by applying an aqueous foaming bacterial preparation to the carpet and then working the fibers to improve the contact, distribution and penetrativ~i of the bacterial preparation. This is moat coxmnonly achieved by use of a.pile brush operated either 25 icy hand or automatically for example, utilizing a cleaning device such as is commonly available commercially. To enhance the penetration of the bacterial preparation, the fibers c~f the oax~ptt may initially be wetted through an agplitation of a detergent 3d solution. M'his is mast commonly applied where the installed carpet. is cleaned u~in~ a cleaning machine prior to t~.c application of the bacterial preparation.
While the carpet fibers are still moist, the bacterial preparation may be applied and worked into the carpet, 35 utilizing the pile brush. Once the carpet has been so treated, it is dried, either by allowing it to dry in the air at ambient tex~erature or through the use of hat air blown through the pile of the carpet to increase the speed of drying of the carpet. Depending upon the state ~0 of the surface materzaJ., the composition may be applied in manor different ways. 2~1~t compcsitic~r~ tnay be apgl~.ed by dipping the material in the CCmpasition or by Spraying tha composition onto the material_ In any of these cases, once the surface material is treated with the composition, the treated material is allowed to dfy by way t~f applied heazt or simply by ambient drying.
The eompoSitipxa.S cad method of the preser~.t invention provide for effective odor control for Surfaces, such as carpet. Thc~ use of the bacterial preparations, particularly the Sp4x~ulated forms of 8aci11us, provide for control of odor caused by depps~.~S
of organic odor causing material on surfaces such as carpets and other fibrous material_ Ozsce the deposit comes isYto coritact with the bacteria, the bacteria germ~.nete, s,nd cor~ttmence growing by feedx~Cig on, the organic material as a food source. This baote~'ial growth commer~Ces wit'izin 20 minutes providing t~aticeable odor reduction xesults within 2~ and 4~ hot~r~ after the bacteria encounter the deposit. It is desirable to 2Q ir~~.tf2illy mask the odor using odox masking agents or neutralize the odor using odt~r neutra3.iaing agents such as sodium bicarbonate or molecular Sieves until the sporul3t.ed bacteria can germinate, grow and effectively decompo:~e the odor causing ag~nt9. The composition also includes suitable protease ar~.d~pr ~.ipase enzymes to commence the digestion of the odor causirxg material until the bacteria commence ~h~!ir growth stage and c~ take over the digestion of the adcsr causing rnat.ex~.al, It is suggestød that for optimum odor control the carpet be treated with the odor cantrøl.l~,ng bacterial preparation an a rout~xxrr~ basis such as after each wet clearing. This carp be easily accomplished after cleaning with the praparatior~, app~.3.ed. tc~ the carpet either when still wet from the clearyrsg or after the carpet has dried. Fxeferably, the preparation is applied to the carpet wl7.ile 5tiI1 wet, worxeed into the carpet with a pile brush and the carpet is allowed to dry naturally.

Tl2e present invention is directed to an aqueous odor control composition for controlling odor associated wi~,h deposits on surfaces, particularly spills of organic material on surfaces, more particularly on carpet.
upholstery or other fibrous material.
1D BACKGROUND bF THE INVEN'fZON
There are many instances where, owing to deposits of orgtiniC ma'texial ran surfaces, offensive odors can arise through tkle presence of the organic material or its decomps~sition. For example, much household waste 15 contains orgar~ie material, which upon decampasi.tion can give xise to offensive odors. This is partiCu~.arljr true where the household waste must be stored for a period of 'time prior to its disposal. Similarly, many fibrous materials utilized in household appliGation.S are a~.so 20 susceptible to soiling bx organic based material, wkx~.ch can give rise fi.o offensive odors. These fibrous materials include carpet. upY~,al,stery, battiri.r~ used for mattresses, pillow aa~i pad. as well as other relatively porous surfaces encountered in the household or 25 commercial environment.
~lariy fibrous materials, such as acrylic, polyester, polypropylene and wool, and particularly nylbxx used in th,e maxzufacture of upholsterx, carpets, batting 34 and hvusehpld fabrics may be susceptihlE to staining especially from the many food dyes used ~,x~. hever$ges and other foods as well as fx~an rather chemicals from many sources. Nylon aa,rpet fibers are often treated with stain blockers such its a sulfonated phenol foxma~.dehyde 35 cvndensate polymer, a sulfonated naphthol formaldehyde oondensate polymer, a kaydrrlyzed vinyl aromatic malefic anhydride polymer, certain iluorochemicals or combinations thereof. The stain blackers net to prevent or reduce the ability of organic dyed, particularly acid dye Cdlorants from chemically reacting wzth and bondixsg to th.e nylon. Z'he fibrQUS material, ~sp,~cia3.ly carpet fibers are also commonly coatiø. with a fluorachem~.oa1 5 anti-soiling agant to imgrove the anti-staining or anti-soiling characteristics of the carpet surface. The anti-soiling fluorochemiCals reduce the t$nca,erlcy of soil to adhere t4 the fiber making the clean up of any spills ør soil on the carpet easier. The fluoroch~nicals also 10 reduce fiber wetability, making for easy cl~aar~, up of licauid.spills through a simple process of blotting the spill. Examp~,eS of Such fluorochemiCdls and other stain resistant chemicals are given, fQr example, ~in U.S.
Pater~t rxutnberc ~, 580, 212 and 4, 925, 707, the disclo~~,,res 15 of which e.xe incox~orated herein. by reference. The use of the stain blackers and fluorocl~.emical~ may not provide c4xttplete stain resistarxce to the carpet, as some materials may still pez»strate the nylon. fibers or react with the fibers, especially if left ire contact with the 20 carpet for extended periods of time. This may be especially ~tue Where the carpefi is exposed to conditions such as direct Sunlight or other 17V sources or high traffic areas, as these conditions may cause the effectiveness of the flucrochemical and stain Mocker 25 coatings to be diminished.
In addition, espdcially in residentie.l locations, the possibility of deposits of organic matter such as feces or urine from babves and pets can result in not 30 only soiling of fibrous and other porous materials such as carpets and bedding but also a lirlger~,ra,g odor ,and may;
in extreme cases, require the replacement of the soiled object. rn the past, various ch~mic~al compounds ha,~cre been prol5osed tb aid in removing odor in a cleaning 35 process. Such chemicals generally act as ado inhibiting 3~er~ts such as U.S. Patent No. 4,996,672 which describes the use of biguanidine polymer compositions as odor inhibiting agents. However, even in Chase cases urhexe the d~posit is cleaned up and odor inhibiting agents utilized. the odor from such deposits may remain in the sailed objects and may become apparent as tk~e effect df the odor masking agents wear off.
deposits of various materials on CaYpet 3xid other fibrous materials may also give riss~ to athcr concerns.
Many of the deposit materials. are capable of supporting bacterial growth, especially iri tkie case of feces which car~.ta~.,ns many bacteria. Some of tk~~ bac'teria that may grow, as a result of a deposit, may ha~cre the potential of causing disease in persons exposed to them, such as mold and mildew. Cax'pet axed ot~7.8x fibrous material are also known, to Gantain a number of naturally occurring bacteria and other organisms. Some of th~s~ bacteria. may ~.Izemselves dive rise to odor duo to ~.r'~.c4mplete digestion of organic material. There have. been attempts to reduce the prosence and number of bacteraa ~Sresetlt in carpet by utilizing varis~us anti-microbial s,gex~ts suG~ as described ~,ri U.S- Patent Nos. 4,110,504 and 5,024,840. These agents are applied to ta.rpet in a manner similar to the way stain blackers axe applied to carpet. The use of Finti--mierobials, while reducing the number of bacteria associated with carpet, may raise other concerns such as the impact Qx~ k~.umary. and animal health and the potential that some of the bacteria may become resistant to etfeCtS
of the anti-microbialS.
Many bacterial and fungal genera are known for exec in odor control due td their capability for producZag enzymes that dxe capable of breaking down organic material. Such bacteria are particularly useful where the orgazxic material, if allowed to remain, will g~.ve rise to malodors. Several such bacterial and fungal genera such ass Bacillus, Lactobacillus, Enterobacter.
Stxe~tococcus, Rt1i2o1~Lt8, Nitrosornonas, Nitrobaetier, ~seudomorias, ~,~caliuens and, K~.ebsi~l.la, ,~mbri.g Dthers, are known for u8e: iri such applications ~nrith Bacillus sp.

Preparations of sporulated Bacillus in a form suitable for spxaying or otherwYise distributirsg an a deposit, egpeaially of pet urine and feces, on a carpet far controlling odor are 15 presently marketed by '1.'he 8ramton Company of Dallas, Texas under the trademark Clr3TRZG~iT. The bacterial preparations are used. to deodorize a deposit by application directly on the deposit. Once the deposit is deodoxiaad. t'he bacteria are depleted from the site or 20 disposed of alonc3 with the deodorized material. Ire the event of a new deposit on the carpet, the treatment must be repeated.
There thus remains a need for a means for txeating ~5 surfaces, particularly carpet and other ~ibrous material to counteract the effects of deposits and especially ~ox controlling odor associated with the deposits, particularly deposited, organic material.

30 Many 7,~acterial genera are. known to produce enzymes fat aWe. c8p2~1~1A of bro8,kixeg ~3owrs c,5rgariio mc~lt~rz.al. Such baatsria arc partiauxs,r~.y useful where this orgaaic material, if allowed to remain, will give rise to malodors. several such bacterial genera such as 35 Bacillus, Lactobacillus, Enterobacter, Strentococcus, Nitrosomana~, Nierobacter, Pseudc~mor~.as, A~.cal~aems axed Klebsiella amongst others are Jmown for use in such applications, with Hacillus and Lactobacillus sp. being the mast prevalent in use in various application .
Strains of bacteria from any of the above noted gen$ra are useful in practicing the present invention.
Preferably, the bacterial preparation fQx use in the present invention is one or more strains of Bacillus pr Lactobacillus, pre preferably, the strains of bacteria far use in the present invention are selected, from ,~cillus licheniformis, Bacillus pasteurii, Bacillus laavolacticus, Haci~~us meaaterium and Bacillus amvlolicruefaciens. Each of these species has characteristics that make them most effective against particular types of organic materials. All of these species are capable of enhanced anaerobic and aerobic growth. Bacillus ~$steurii is known for superiar lipase production, while Hacillus laevolacticus has a very fast germination cycle. Bacillus amvloliauefaeiena is high in production of protease enzymes.
The selection of the strains of baGberia for use ~0 is the present invention may depend upon many factors.
One rush factor is the nature of the organic material most commanly expected for the particular applieatipn, For exan~.pl~, in a commercial application, the mast commonly expected deposits would be soil tracked in from out-of-doors, beverages such as coffee, tea, Qther food and the like, especially in a restaurant environment, and pQSSibly, inks~or Goners for printers sad otrier office equipment. Many of these materials are high in fatty components so the bacterial preparation may be QnhanCed for strains having high activity against such materials.
Qne example of such a bacteria is Hs~~llus pasteurii known for superior lipase production. zn a residential environment, the nature of the $eposits may differ with out-of-doors soils. Beverages, food anc3 urine and feces from pets and children being most commonly enoauntered.
Depending upon the nature of the deposited material, the preparation may be selected t4 Gbrit~i~ strains having enhanced activity against rush materials, ~yQthex factor _ 7 that may affect the nature of the deposit is the geogxaph~.ca~, location o~ the suxface being treated. This factor would especially relate to the nature of deposits of out-of-doors sail and to the nature of food deposits.
5 Different regiana are known to have different soil types and different regions may also have differences in the foods commonly consuz~ed due to cultural and environmental factors_ In addition, the temperature of the carpet to be treated will ix~,fluextoe the activity o~ the bacteria.
10 Depending on the strain selected the bacteria will tend to exhibit enhancec'i activity at higher temperatures. At lower ambient temperatures, more active strains xna.y be desired.
15 ~~,e bacterial preparation will typically comprise one or more strains selected from the genera and Species described above: ~nlhen utilizing a mixture of more than one strain, each of the individual strains may comprise between 3~ and 97~ of the total of the bacteria present 2Q in the preparation. Depending upon the bacteria, these percentages are based ost the total cell aumk~er or CrJlol'~y farming units or the total mass of tk~~ bacterial preparation. For the Bacillus sp. the percer.~tages are based on total Cell txu~nber. Hxe~~xably, each of the 25 strains is preset7,t ire sufficient numbers t.o make up 1p$
to 70~ of the total bacteria in the preparation. When mixtures of more tha.~x two strairm are employed. eech of the strains is most pr~afera?~ly praserxt irA az~ tamourat a~
from 20~ to 40~ of the total bacteria in the preparat~.or~.
30 partiCUlarly preferred preparations far general use in almost all applications are as follaras:

Bacillus nasteurii, sacillus laevol~cticus and Bacillus 10 amYloliQUefaciens and combinations thereof are provided in a state in which the compasitiarf may be applied to d surface, such as carpet fiber or other fibrous material.
The effective amount is a sufficient number of bacteria to provide a relativa7.y uniform coverage of the syxrfe.ce 15 exposed to a deposit of as odor ca~.siz~g oxganic ms.teri~l.
The bacteria will then undergo rapid growth and consume the odor causirsg matex~~.a~.. The factors that Geri affect the number of bacteria to $e used relate in most part to the nature of the surface to be protested. For carpet, 20 such factors 3xaolude the nature or the fiber in terms of the material, a.g. zxylOn or pplypropylene and the like, the characteristics of the yarn in the terms of the denier and number of filaments and the Gharacteristic~5 c~f the fiber in terms of the number of yarns and the twist.
25 These factors relate to the nature of the carpet in terms of the weight (oz) or (g) and height of the pile. All s~f these factors will affect the ambunt of e.5cpas~d surfaoe of the fibers that m~,gY~t be covered by the bacterial p~el7~x'd:~a.8ri.. lPor mamt applications on carpet, between 30 about 106 and 10$ cells per ml of the compositior~. is preferred.
The compositions are provided as a preparation of a suspensions of the kl~acillus species. oxie or maze enzymes 35- and a non-residual surfactant in a suitable aqueous carrier, such as distilled water, tap water, a saline solution or other such aqueous solutions.
The bacteria and particularly Bac,~llus species are provided as dormant cells. The term "dormant cells" is intended to encompass cells which are in a state which are reqv.ired to be activated before they can undergo 5 growth. One example flf a dormant Cell is a sporulated farm of the bactexia where the spores must undergo activation and ger~tination before growth of the bacteria can occur.
10 $y providing the bacteria iri a dormant or sporulated form, the bacteria are protected from environmental factors which may prove detrimental to active bacterial oells. These envirox~mental factors may iriGlude exposure to heat, chemical agents, axxd UV
15 radiation from sunlight &s well as the exposure to air for those strains that may be predominantly anaerobic.
The sporulated or dormant strains of bacteria become activated and undergo germination in response to 20 being exposed to organic material including organic material that can cause odors. The factors that promote the activation of the dormant Qx sparulated bacteria include the moisture and various organic compounds present in the deposit o~ organic material. Once 25 activated, the bacteria undergo growth and replication, consuming the organic material in the deppsit until the material is depleted.
The bacterial preparation tttay be provided as a 30 concentrate to be diluted with the other ingredients.
The concentrate may include other agents far improving viability of the bacterial preparation. The cpncCntrate preferably contains between x0 arid 20 times the number of cells or spores per ml of the final compQSitian.
35 Typically, the concentrate contains about 109 cells per ml. The concentrate ie diluted with water or other agueous carrier and the other ingredients to produce the _ 1~ _ composition which is directly applied to installed surfaces, for example, installed carpet.
The composition also includes other agents namely one or mare enzymes, and a non-residual surfactant in addition to the ~aacteria spore bland. The enzymes typically employad in the composition are one or more 3ipase or protease enzymes, particularly amylase. The non-residual surfactant is one which does not leave an 10 appreciable residue upon drying. The nature of the surfactaxxt will be selected based upon the non-residual property. Particularly preferred surfactants are the sulfosuccinate anionic surfactants, more particularly the sodium dialkyl sulfosuccinates and most particularly 15 sodium dihexyl sulfosuccinates such as COLALJET MA-80 available from The T~i,orn~.ey Company, Wilmington, DE.
The odor controlling bacterial composition of the present invention may be provided with other ingredients 20 depending upon tb,e apgl~.c~,tiQx~ or suxface to be treated, such as masking agents, anti-Foaming agents, or foaming agents. The masking agents are gansrally fragrances such as vanilla or trash scent t.v zs~~.ti.al3.y mask t'~ odox associated with the material on the aaxpet. The az~ti-25 foaming agent far reducing surface terssion for reduced-absorbent surfaces may be arry commonly utilized anti-foaming agent which would be suitable for the surface to be treated. One exampla of suckr an ar~.ti-foaming agexxt is a sil.iGQnc bas~od anti-foaming ag~rit, Which m$y $e 30 utilized in compositions utilized. for txeating reduced absorbent surfaces, such a,s hard surfaces. Mme ar~ti-foaming agent may also be used in compQSi~ipns Wl~~,ch are utilized in a spray bottle for direct application by the consumer, particularly fQr carpet ox oth~rr fibrous 35 material.
Another additional ingredient which may be utili2ed iri the cOmpbSition depending upon the ~~ 11 -alapliaa~tian is a foaming agent far producing a foam ,aampasition for treating relatively absorbent surfaces, S~xCb as ad.xptt. . This foaming agent is preferably a lauryl sulphate, rrtpre preferably an ammonium lauryl 5 sulphate or sodium lauryl sulphate, most preferably sadstlm ldLtryl Sulphate. the foaming agent is utilized to produce a composition which can be applied to the surfaces of higher absorbency to allow the eompositian to he worked into the surface. This may be of particular 10 use for treating carpet. The additional ingredients would be utilized in the comgosxtions at the usually employed Cancentrations~ generally 5 percent by weight or less based upon the total weight of the compQsit,ian.

When applying the composition to wn insta3.led carpet, it is not essential, but preferred t#aac t'h~s cQmpQSition be applied c~.c~rQUghly and evenly throughout the length of the pzle, especially reaching doom to the base of the ,pile til3er. Tfais is 20 generally achieved by applying an aqueous foaming bacterial preparation to the carpet and then working the fibers to improve the contact, distribution and penetrativ~i of the bacterial preparation. This is moat coxmnonly achieved by use of a.pile brush operated either 25 icy hand or automatically for example, utilizing a cleaning device such as is commonly available commercially. To enhance the penetration of the bacterial preparation, the fibers c~f the oax~ptt may initially be wetted through an agplitation of a detergent 3d solution. M'his is mast commonly applied where the installed carpet. is cleaned u~in~ a cleaning machine prior to t~.c application of the bacterial preparation.
While the carpet fibers are still moist, the bacterial preparation may be applied and worked into the carpet, 35 utilizing the pile brush. Once the carpet has been so treated, it is dried, either by allowing it to dry in the air at ambient tex~erature or through the use of hat air blown through the pile of the carpet to increase the speed of drying of the carpet. Depending upon the state ~0 of the surface materzaJ., the composition may be applied in manor different ways. 2~1~t compcsitic~r~ tnay be apgl~.ed by dipping the material in the CCmpasition or by Spraying tha composition onto the material_ In any of these cases, once the surface material is treated with the composition, the treated material is allowed to dfy by way t~f applied heazt or simply by ambient drying.
The eompoSitipxa.S cad method of the preser~.t invention provide for effective odor control for Surfaces, such as carpet. Thc~ use of the bacterial preparations, particularly the Sp4x~ulated forms of 8aci11us, provide for control of odor caused by depps~.~S

This baote~'ial growth commer~Ces wit'izin 20 minutes providing t~aticeable odor reduction xesults within 2~ and 4~ hot~r~ after the bacteria encounter the deposit. It is desirable to 2Q ir~~.tf2illy mask the odor using odox masking agents or neutralize the odor using odt~r neutra3.iaing agents such as sodium bicarbonate or molecular Sieves until the sporul3t.ed bacteria can germinate, grow and effectively decompo:~e the odor causing ag~nt9. The composition also includes suitable protease ar~.d~pr ~.ipase enzymes to commence the digestion of the odor causirxg material until the bacteria commence ~h~!ir growth stage and c~ take over the digestion of the adcsr causing rnat.ex~.al, It is suggestød that for optimum odor control the carpet be treated with the odor cantrøl.l~,ng bacterial preparation an a rout~xxrr~ basis such as after each wet clearing. This carp be easily accomplished after cleaning with the praparatior~, app~.3.ed. tc~ the carpet either when still wet from the clearyrsg or after the carpet has dried. Fxeferably, the preparation is applied to the carpet wl7.ile 5tiI1 wet, worxeed into the carpet with a pile brush and the carpet is allowed to dry naturally.
