【０００１】
【産業上の利用分野】
本発明は、バチルス（Bacillus) 属に属する新規微生物に関する。
【０００２】
【従来の技術】
排水浄化菌としては、各種のバチルス属微生物が知られている。しかしながら、排水浄化においては、単に浄化に止まらずに、その脱臭や、金属物質の除去も大切な要素である。
【０００３】
しかしながら、現在までに知られているバチルス属微生物では、これらの全ての要素を満足する微生物は発見させれおらず、そのような微生物が強く望まれていた。
【０００４】
【発明が解決しようとする課題】
そこで、本発明は、排水の単なる浄化とともに、その脱臭や金属除去もできる新規な微生物を提供することを目的とするものである。
【０００５】
【課題を解決するための手段】
本発明らは、上記のような要素を全て満足することのできる有用な新菌株を求めて鋭意探索したところ、浄化、脱臭、金属除去の全ての機能を有する一菌株を土壌から分離することに成功した。この一菌株の菌学的性質の試験および分類は、下記の文献に従い行なった。

[Industrial application fields]
The present invention relates to a novel microorganism belonging to the genus Bacillus.
[0002]
[Prior art]
Various bacteria of the genus Bacillus are known as drainage purification bacteria. However, in wastewater purification, not only purification but also deodorization and removal of metal substances are important elements.
[0003]
However, the Bacillus microorganisms known to date have not found any microorganisms that satisfy all these factors, and such microorganisms have been strongly desired.
[0004]
[Problems to be solved by the invention]
Accordingly, an object of the present invention is to provide a novel microorganism capable of deodorizing and removing metal as well as simply purifying waste water.
[0005]
[Means for Solving the Problems]
The present inventors have eagerly searched for a useful new strain that can satisfy all of the above-mentioned elements, and have isolated one strain having all functions of purification, deodorization, and metal removal from the soil. Successful. The test and classification of the bacteriological properties of this strain were carried out according to the following literature.
[0006]
(1) Bargey's Manual of Determinaitive Bacteriology 8th Edition (1994)
▲ 2 Bergey's Manual of Systematic Bacteriology 2nd Edition (1986)
(3) The Genus Bacillus (1973) (US Department of Agriculture)
[0007]
As a result, the microorganism was identified as a Bacillus because it is a Gram-positive bacillus that forms heat-resistant spores, but the analysis result of the bacterial cell component is any bacterial species described in the above literature It was confirmed that it was a new bacterium belonging to Bacillus. The microorganism is deposited at the Microorganism Deposit Center of the Institute of Biotechnology, National Institute of Advanced Industrial Science and Technology as Bacillus sp. CCC-a (deposit number: FERM P-16175).
[0008]
Hereinafter, the mycological properties of the novel microorganism belonging to the Bacillus of the present invention will be described.
[0009]
The novel microorganism of the present invention grows well in any medium that is a general nutrient medium.
[0011]
The culture preferably grows well at about 5 to 30 ° C.
[0012]
The novel microorganism of the present invention can be dispersed in water or a liquid medium and used for various purposes in the form of a dispersion. Preferably, the microorganism group is immobilized on a carrier and used as a carrier-immobilized microorganism group that facilitates handling. .
[0013]
As a carrier for immobilizing a microorganism group, it is preferable that the holding capacity of microorganisms is large and the activation of microorganisms is easy.
[0014]
As the carrier, rocks (for example, pearlite, diatomaceous earth) or a pulverized product thereof, gravel, sand, plastics, ceramics (for example, alumina, silica, natural zeolite, synthetic zeolite), talc and the like are also preferable. A porous material having continuous ventilation holes such as porous plastics is preferred. For example, a fine powder (trade name: pearlite) obtained by holding a pearlite pulverized product at a high temperature and high pressure and heat-treating and then rapidly reducing the pressure to make it porous is preferable because it has the property of causing fungi to grow. In such a porous material, the diameter of the vent is preferably about 2 to 10 μm. The carrier may have any properties such as a lump, granule, powder, fine powder or crumb, needle, etc., but preferably has an average particle size of 2 mm or less, particularly 50 μm to 1 mm. Good granular material. Such a carrier-immobilized microorganism group may be housed and used in a container having good water permeability or air permeability such as cloth or net as necessary.
[0015]
In addition to these, a ribbon-like or sheet-like woven fabric or non-woven fabric can be used as the carrier.
[0016]
In order to support the microorganism group on such a carrier, the carrier and the microorganism group dispersion of the present invention are mixed and then dried, but the microorganism group may be directly cultured on the carrier.
[0017]
Loading amount of microorganisms in the carrier varies depending on the conditions at the time of loading, preferably, 5 to 200 billion pieces / cm 3, preferably 10 to 100 billion pieces / cm 3.
[0018]
The carrier-immobilized microorganism group of the present invention is effective for purification of waste water. Moreover, the deodorizing effect was confirmed by using the novel microorganism of the present invention in pig farms, public toilets, and the like. Furthermore, in the novel microorganism of the present invention, the function of recovering metals such as phosphorus was confirmed. Furthermore, the effect was confirmed also in soil improvement.
[0019]
The safety of the novel microorganism of the present invention was confirmed by an oral administration test using mice.
[0020]
【Example】
Next, examples of the present invention will be described.
First, a medium having the following composition was prepared.
[0021]
Medium Peptone 5g
5g meat extract
NaCl 2.5g
500 ml of water (pH 7.0)
The medium having the above composition was placed in a 1000 ml container, Bacillus sp. CCC-a was inoculated therein, stirred well, allowed to stand, and cultured at 30 ° C. for 3 days.
[0022]
The obtained culture broth was centrifuged to separate the cells, washed thoroughly, and attached to a carrier to obtain a powder. The carrier used was diatomaceous earth baked and pulverized.
[0023]
This powdery Bacillus sp. CCC-a was inoculated into the object to be weighed, and the changes over time in COD, total nitrogen amount and total phosphorus amount were measured. The test was carried out according to JIS 0102-17 for COD, JIS 0102-45.2 for total nitrogen, and JIS 0102-46.2 for total phosphorus. As an object to be measured, a solution obtained by adding 0.2 g of starch per liter to 100 times of milk in seawater was used. The one as it was was used as a comparative example, and the one inoculated with Bacillus sp. CCC-a was used as an example. The test was carried out at 20 ° C. Moreover, in measuring each amount, the liquid to be measured was allowed to stand for 2 hours, and the supernatant was used as a test liquid.
[0024]
The test results are shown in Table 1. In the test, two samples were prepared for each, and the average was used as the measured value.
[0025]
[Table 1]
As can be seen from Table 1, it was found that Bacillus sp. CCC-a, which is a novel microorganism of the present invention, has a water purification function and an action of removing metals. Furthermore, the powder of Bacillus sp. CCC-a was sprinkled on a single rotten cocoon, and the odor was clearly reduced after 2 hours. In addition, Bacillus sp. CCC-a was sprinkled on fresh strawberries and stored at 25 ° C., and no odor occurred even after 48 hours. On the other hand, the strawberry stored at 25 ° C. without being sprinkled with Bacillus sp. CCC-a became quite odorous after 24 hours.
[0027]
Thus, Bacillus sp. CCC-a of the present invention also has a deodorizing action and a freshness preserving action.
