Abstract:
본 발명은 연안 갯벌에서 유기물 분해능이 매우 우수한 것으로 알려진 갯지렁이( Perinereis aibuhitensis )에 내생하고 있는 미생물을 MA 배지에서 생장하여 나타난 집락(colony)의 색깔과 모양에 따라 선별한 31개의 집락을 별도로 선별하여 순수배양한 후 16S rRNA 염기서열에 기초하여 동정한 결과, Bacillus 속에 포함되는 균주를 분리하였다. 갯지렁이로부터 분리하여 선별한 두 Bacillus 균주 CBW4와 EBW4는 단백질, 탄수화물, 지질 분해능이 뛰어나고 염분에 내성을 갖고 있으므로 유기물로 오염된 양식장 폐수 환경을 정화하는데 유용하게 쓰일 수 있을 것이다.
Abstract:
According to the present invention, microbes which live in Perinereis aibuhitensis in coastal mud flats have been grown in an MA culture medium and colonies have appeared, wherein the Perinereis aibuhitensis is known to have excellent degradability of organic matter. Thirty-one colonies have been separately selected according to the colors and shapes of the colonies which have appeared in the MA culture medium. Strains belonging to Bacillus genus have been isolated as a result of identification on the basis of 16S rRNA sequences after a pure culture process of the 31 colonies. Bacillus strains EBW4 and CBW4 isolated from the Perinereis aibuhitensis have excellent degradabilities of protein, carbohydrate and lipid and have resistance to salt. Accordingly, the EBW4 and CBW4 can be practically used to purify the wastewater environment of a farm contaminated with organic matter.
Abstract:
The present invention separated a strain included in Bacillus sp. from the result of identification based on base sequence 16S rRNA after pure cultivating, by separately selecting thirty one colonies selected according to colors and shapes of colonies, generated by growing microorganism, arbuscular, in perinereis aibuhitensis known to have excellent ability of decomposing organic matters in mud flat along the shore, in MA medium. A strain CBW4 selected by being separated from perinereis aibuhitensis can be usefully used in purifying the environment filled with waste water in a farm contaminated due to the organic matters, by having salinity tolerance and excellent ability of decomposing protein, carbohydrate and lipid.

Abstract:
In the present invention, an enrichment culture is used to separate a microorganism from mud, whose strain name is EDB-2 and has an excellent ability to decompose endosulfan and organic materials, and the microorganism is analyzed for physiology properties and biochemistry properties. The result of the analysis shows that the microorganism has a 99% similarity to Rhodococcus pvridinivorans. The EDB-2 is aerobic, positive to gram, a bar type and pink. The growth temperature range of the EDB-2 is relatively large, the growable temperature being 20-45°C, and the optimal temperature thereof is 20-42°C, The EDB-2 cannot hydrolyze casein and cellulose but can decompose DNA, agar, starch and tween, which means the ability of the EDB-2 to decompose lipid is excellent. Accordingly the invention can be expected to be used for purifying marine waste water contaminated by organic materials.
