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 Bacillus 균주 CBW4는 단백질, 탄수화물, 지질 분해능이 뛰어나고 염분에 내성을 갖고 있으므로 유기물로 오염된 양식장 폐수 환경을 정화하는데 유용하게 쓰일 수 있을 것이다.
Abstract:
In the present invention, an enrichment culture is used to separate an EDB2 microorganism from mud, which excellently decomposes endosulfan and organic materials. A result of an analysis of the physical and biochemistry properties and genetic properties thereof shows the separated microorganism from the mud has a 99% similarity to Rhodococcus pvridinivorans.The separated microorganism is aerobic, positive to gram, a bar type and pink. The growth temperature range of the microorganism is relatively large, the growth temperature being 20-45°C, and the optimal temperature is 20-42°C. The microorganism can not hydrolyze casein and cellulose but can hydrolyze DNA, agar, starch and tween, which means the ability to decompose lipid is excellent. Accordingly the present invention can be used for purifying marine waste water contaminated by organic materials.
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.
