Description

TECHNICAL FIELD The present invention relates to an odor control composition comprising odorless microorganism methylobacterium brachyurtum,

The present invention relates to an odorless microorganism , The present invention relates to a composition for preventing odor and a method for preventing odor using the same.

Clean air is recognized as the basis for human health and well-being, and unpleasant odors or contaminated air act as a major factor impeding a pleasant environment. For example, unsatisfactory indoor air quality in enclosed conditions is caused by two important factors: One is the indoor air pollutant generated directly from the constituent material itself (building, vehicle, etc.) constituting the enclosed environment and the other factor is the smell generated by the substance caused by human activity or the influx from the outside .

Air conditioning system is a system that optimizes the indoor environment by lowering indoor temperature by aiming to harmonize air temperature, humidity, air flow and cleanliness in buildings, vehicles, railways, ships, and aircraft. These air conditioning systems are increasing in penetration rate due to the improvement of living standards. There have been many improvements in the basic functions due to the increase of the air conditioning system, but there are still many problems to solve due to the environmental aspect for the indoor air quality.

In air conditioning systems, air-conditioner odor is known to be attributed to fungi and the metabolites of bacteria, but specific data on the types of fungi and bacteria and how the microorganisms specifically secrete certain metabolites have yet to be found It is in a state that it is not.

In the structure of the air conditioner, all the air passing through the blower passes through the evaporator core. When heat exchange is performed between the cold refrigerant and the air, condensation condensation phenomenon occurs on the evaporator surface depending on the temperature difference. Is provided with a good environment for fungi and bacteria to form and propagate. When fungi and bacteria are proliferated on the EVA core exposed to the outside air, volatile organic compounds (mVOCs) of the microorganisms are generated as the metabolites of the bacteria that have proliferated on the surface of the EVA core, and air passing through the EVA core is blown into the room The volatile organic compounds generated by the microorganisms may expose the room to odors caused by fungi and bacteria during long-term use.

The EVA core surface, which generates bad odors, is covered with biofilm according to long-term use. They are composed of bacteria, cell clusters and EPS. EPS is composed of protein, polysaccharide, polyuronic acid, Nucletic, and Lipid. On the surface of EVA core, various bacteria and fungi multiply as biofilm, and organic compounds (mVOCs) by microorganisms are emitted as metabolites. Many factors of odor are known as corruption.

Various types of fragrances are commercially available to remove the odor. However, it is often the case that the fungi and germs living in the EVA core can not be fundamentally removed, but merely temporarily serve to dilute an unpleasant smell. Antimicrobial agents have not yet been developed to act specifically on certain fungi or bacteria in the eva core, and are sold only because of the antimicrobial activity against common pathogens.

 Accordingly, in Korean Patent Laid-Open Publication No. 10-2012-0020309, the present inventors have proposed a method for preventing the deposition and propagation of germs and fungi on the surface of Eva core, Discloses a method for producing an EVA core in which a film is coated.

However, in the above-mentioned invention, it is not possible to show which bacteria are odorless microorganisms. If the microorganisms are coated with the microorganisms, it can be determined whether they can survive in the EVA core and whether the microorganisms that cause odors such as odor There was insufficient evidence for the effect.

In the present invention, what is evaluated as "odorless" means "a state in which nothing can be detected by the smell of people selected on a predetermined basis".

In relation to the evaluation of odor, the sensory evaluation method using the sense of smell according to the current law is to be evaluated. Odor evaluations other than odor evaluation do not exist globally. As shown in the above-mentioned embodiments, the criterion of 'odorless' is determined according to the criteria that the human senses by the sensory evaluation method.

The criterion for determining the odorlessness is described in the odor process test method (Notification No. 2007-17, National Institute of Environmental Research). On page 65 of the Odor Control Test Method, the odor determination chart states that 'odorless' means 'a state in which nothing can be detected with normal olfaction'.

In addition, the contents of pages 65 and 66 of the odor process test method, which stipulates the criteria for selection of people who can take odor evaluation, can be seen to be a clearer standard.

In addition, as can be seen on page 2 of the Japanese Standards for the Control of Odor, Chapter 2 of Regulation Article 4, it can be seen that the portion corresponding to 0 in the rating table is described as "odorless".

As described above, the criterion of 'odorless' in the sensory evaluation means, as clearly defined in the above-mentioned domestic and Japanese regulations, "the state of being unable to detect anything by the smell of people selected on a certain standard".

Example  8: Evaluation of Optimum Adhesion Condition of Odorless Microorganisms

(1) Analysis of optimal concentration of adhering microorganisms on fin

In order to coat the 11 kinds of odorless microorganisms with EVA core, the adherence concentration for inoculation at 10 ⁶ cfu / g level was confirmed as in the 2012 study (priority application). Methylobacterium aquaticum , one of the common strains, was cultured from 28 ℃ to late log phase, washed with sterile 0.85% saline and incubated at 4 ℃ for 18 hours. After incubation at 4 ° C, the optical density was adjusted to 0.749, 0.588, 0.55, 0.5, and 0.45. 2 g of u-shaped fin was immersed and shaked at a constant rpm for 1 hour at room temperature. The fins with the microorganisms of each concentration were desorbed through a mixer, and then serial dilution was performed on the R2A agar plate.

As a result of the flat plate smear, it was confirmed that the concentration of the microorganisms adhering to the fin changes according to the OD value. OD 0.749 showed 1.53 × 10 ⁸ ± 1.52 × 10 ⁷ cfu / g fin adhesion, OD 0.588 and 0.55 were 4.00 × 10 ⁷ ± 1.00 × 10 ⁷ cfu / g fin and 1.03 × 10 ⁷ ± 8.50, respectively. X 10 &lt; ⁵ &gt; cfu / g fin. In addition, OD 0.5 and OD 0.45 showed 6.00 × 10 ⁶ ± 7.00 × 10 ⁵ cfu / g fin and 2.53 × 10 ⁶ ± 3.51 × 10 ⁵ cfu / g fin, respectively. . 10 kinds of odorless microorganisms were coated by using the OD value of coating the microorganisms at the level of 10 ⁶ cfu /

(2) odorless microorganisms Eva Core  And fin Attachment  Confirm

As a result of the experiment with fin, 11 kinds of odorless microorganisms showed the same degree of adhesion at the same OD regardless of genus. Therefore, the amount of microorganisms adhering to the eva core was confirmed by using a culture medium of the same OD as fin by using Methylobacterium aquaticum , one of the strains.

Methylobacterium aquaticum titrated to OD 0.5 showed 8.95 × 10 ⁶ ± 5.51 × 10 ⁵ cfu / g fin adhesion on Eva cores. In the case of the EVA core attached with the same culture solution, the degree of attachment of 2.55 × 10 ⁶ ± 3.51 × 10 ⁵ cfu / g fin was exhibited. These results indicate that the same level of microorganisms are attached to the culture medium when the same OD medium is used.

Example  9: 30-day survival assessment of 4 combinations

A survival assessment for 30 days was performed in the following combinations. The combination number and microorganism list of the microorganisms used in the coating combination are as follows (Table 11).

Combination One Methylobacterium aquaticum PR1016A 2 Caulobacter vibrioides TX0632 3 Methylobacterium brachiatum TX0642 4 Bradyrhizobium diazoefficiens TX0618

The combination was constructed for a 30-day short-term impact assessment of the odorless microorganism combination separated from the taxi, and a short-term evaluation for 30 days was conducted on this community.

In the case of the above combination, Methylobacterium aquaticum PR1016A, Caulobacter vibrioides TX0632, Methylobacterium Brachiatum TX0642 and Bradyrhizobium diazoefficiens TX0618 were found to have a total bacterial count of 3.99 × 10 ⁶ ± 2.82 × 10 ⁶ cfu / g fin at time 0. The red and white colonies were 3.62 × 10 ⁶ ± 2.79 × 10 ⁶ cfu / g fin, 3.67 × 10 ⁵ ± 3.06 × 10 ⁴ cfu / g fin. After 30 days, no white colony was detected, and a red colony was detected at 2.14 × 10 ⁶ ± 1.25 × 10 ⁵ cfu / g fin, the same as the total bacteria (FIG. 2).

As a result of confirming the number of individuals through REP-PCR, the combination of time 0 was 43 samples out of 111 representative samples, Methylobacterium aquaticum PR1016A, Caulobacter vibrioides TX0632 contains six samples, Methylobacterium It was confirmed that 52 of brachiatum TX0642 and 10 of Bradyrhizobium diazoefficiens TX0618 were present. These results indicate that Methylobacterium sp. And 2% of the total combinations were 85.6% (FIG. 3).

30 days REP-PCR patterns of Methylobacterium aquaticum PR1016A analysis of the results of representative microorganisms 89 points and 26 points after, Methylobacterium Brachiatum TX0642 was found to survive at a ratio of 63, indicating that Methylobacterium sp. Shows dominance and survival in the eva core environment regardless of the progress of time. In addition, the culture of external microorganisms could not be confirmed.
