PURPOSE: A nutrition enhancing agent for marine cultivation is provided to promote the growth of shellfish and fish eating marine microalgae and to enhance the immune function of the shellfish and fish. CONSTITUTION: A nutrition enhancing agent for marine cultivation is produced by the following steps: cultivating microalgae at a density of 10million cell/ml; condensing the cultivated microalgae using a hollow fiber membrane filter to maintain living cells; freezing the condensed microalgae; and microencapsulating the obtained unsaturated fatty acid. The hollow fiber membrane filter includes pores with a size smaller than 0.01micrometers.
Abstract:
A nutrition enriched medium for the marine microalgae is provided to reduce the culture period of microalgae and improve the productivity by adding the material useful for growth acceleration and immunologic function reinforcement of the microalgae in the mass culture of the marine microalgae. The nutrition enriched medium for the marine microalgae is prepared by mixing the seawater with the agricultural fertilizer which contains 16.47-24.71 mg of nitrogen and 1.73-2.60 mg of phosphorus based on 1 liter of seawater and cytokinin which promotes the cell division of the marine microalgae.

본 발명은 개불 성체가 들어있는 수조의 온도를 평소보다 3~5℃ 올리고 동시에 식물성 플랑크톤의 농도를 평소보다 높여서 산란을 유발하는 단계와, 상기 수정된 알과 정자를 세란하는 단계와, 상기 수정란을 분조하여 지수상태에서 부화시키는 단계와, 상기 부화된 유생을 15~20℃의 사육수조에 넣고 30일정도 사육하여 치충을 얻는 단계와, 상기 치충을 저질이 충진된 수조에 넣어 성체가 될 때까지 사육하는 단계로 구성된 개불의 사육방법을 제공하기 위한 것으로, 본 발명은 인공으로 개불을 대량 생산가능하도록 하므로써 고부가가치 양식생물 생산에 의한 어민소득 증대를 꾀할 수 있고, 수산자원의 효율적인 이용은 물론 양식품종의 다변화에 의한 국제 경쟁력 향상을 기할 수 있으며, 또한 개불 치충을 오염된 연안 저질에 방류함으로써 오염된 연� � 간석지의 환경을 정화 및 개선하고 연안 생태계의 친환경적 복원이 가능하게 되는 매우 유용한 발명인 것이다.
Abstract:
PURPOSE: A method for rearing urechis unicinctus is provided to enable a mass production of artificial seeds of urechis unicinctus by satisfying the conditions of habitat and reproduction ecologies of urechis unicinctus. CONSTITUTION: The method comprises the steps of: inducing spawning by increasing the temperature of an aquarium containing urechis unicinctus by 3 to 5deg.C higher than usual and increasing the concentration of phyto plankton higher than usual; cleaning fertilized spawns and sperms; dividing the fertilized spawns to hatch the same in a cutoff state; putting the hatched larvae in a rearing aquarium of 15 to 20deg.C and rearing the same for about 30 days to obtain young urechis unicinctus; and putting the young urechis unicinctus in an aquarium filled with bottom materials and rearing the same until the young urechis unicinctus become adults.
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.

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.
