Abstract:
The present invention separates a 11 strain which is included in a bacillus as a result of identifying based on a 16S rRNA sequence by separately selecting and purely culturing 31 colonies which are selected according to the color and shape of a colony which appears by growing a microorganism, which lives in a perinereis aibuhitensis which is known to have an excellent organism decomposition in a coastal mud flat, in an MA medium. The present invention can be used to purify a mud flat environment which is contaminated with organic matters since seven species of bacillus spp. including bacills algicola, bacills anthrasis, bacills aquimaris, bacills barbaricus, bacills hwajinpoensis, bacills nanhiensis, and bacills vietnamensis live in a perinereis aibuhitensis as a research result of analyzing the diversity of 11 strains which are included in a Bacillus genus and two species of strains which are selected by a separation from the perinereis aibuhitensis have an excellent function for decomposing a protein, a carbohydrate, and a lipid and have a tolerance to salt.

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 11 균주를 분리하였다. Bacills 속(genus)에 포함되는 11 균주의 다양성을 분석한 결과 Bacills algicola, Bacills anthrasis, Bacills aquimaris, Bacills barbaricus, Bacills hwajinpoensis, Bacills nanhiensis, Bacills vietnamensis 등 모두 7 종 (species)의 Bacillus spp.가 갯지렁이( Perinereis aibuhitensis )에 내생하는 것으로 조사되었다. 본 발명에서 갯지렁이로부터 분리하여 선별한 두 Bacillus 균주들은 단백질, 탄수화물, 지질 분해능이 뛰어나고 염분에 내성을 갖고 있으므로 유기물로 오염된 갯벌 환경을 정화하는데 유용하게 쓰일 수 있을 것이다.
Abstract:
The present invention isolates a microorganism with a bacterial name of EDB 2 in a coastal mud flat via enrichment and analyzes the characteristics of the microorganism that has excellent capacity for decomposing edosulfan and organic matters. As a result of the analysis of the physiobiochemical and genetic characteristics of the EDB2 bacterium, the EDB2 bacterium is 99% similar to Rhodococcus pyridinivorans. The EDB2 bacterium is aerobic, Gram-positive, bar-shaped and pink. The growth temperature range of the EDB2 bacterium is relatively wide as growability temperature ranges from 20 to 45°C and optimal temperature ranges from approximately 20 to 42°C. The EDB2 bacterium has strong possibility of being applied to purify lipid-polluted environment as the EDB2 bacterium does not have hydrolytic capacity for casein and cellulose but has decomposing capacity for DNA, agar, starch and tween, thus having excellent lipid-decomposing capacity. The EDB2 bacterium is acetoin-, urease-, α-glucosidase-, β-glucosidase-, mannitol-, malate-, alkalinephosphate-, esterase lipase-, leucine arylamidase-, trypsin-, acid phosphate-, esculin-, and sorbitol-positive.
Abstract:
PURPOSE: A vacuum suction type of mud flat deposit collector has a sample collecting tube that can naturally enter inside a mud flat without applying artificial forces on a sample collection tube upon sample collection. CONSTITUTION: A vacuum suction type of mud flat deposit collector comprises the upper cap (30) and the cylinder rod (41). Said upper cap forms the cover (20) capable of opening and closing in the center of the top face. In said cylinder rod, a through-hole is formed in the center of said cover, around which the cylinder (40) and the first handle (10) are connected respectively to both end parts. A part of said upper cap is provided with the second handle (11). A lower part of said upper cap comprises the sample collection tube (50) that is divided into more than one and is connected.

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.
