Abstract:
본 발명은 해양 주상 시추 코어 시료 광학 촬영 자동화 시스템 및 촬영 방법에 관한 것으로, 더욱 상세하게 길이가 1 m 이상에서 수십 m의 긴 코어(주상 시추) 퇴적물을 일정 길이로 절단하여 길이측정부가 형성된 시료트레이에 수용되도록 한 다음, 제어부에 의해 카메라가 x, y, z축 방향으로 자동 이동하여 시료를 왜곡 없이 분할 촬영한 후, 길이측정부에 의해 나타난 치수를 바탕으로 분할 촬영된 이미지를 오차 없이 정확한 위치에 합성하여, 정밀한 이미지를 획득할 수 있는 해양 주상 시추 코어 시료 광학 촬영 자동화 시스템 및 촬영 방법에 관한 것이다.
Abstract:
The present invention relates to an identification method of species of diatoms inhabiting the coast of Korea, and a polynucleotide probe, a DNA chip and a kit for identification for species of diatoms for the method. The identification method comprises the following steps: carrying out polymerase chain reaction (PCR) of the DNA extracted from diatoms to obtain a PCR product; binding the PCR product to each probe comprising a base sequence identical or complementary to one or more DNA sequences of sequence numbers 3-51; and identifying the species of the diatoms according to whether the PCR product binds or not. The present invention can analyze the genotype of diatoms inhabiting the coast of Korea and can simply, rapidly and accurately identify the species thereof on the basis of single nucleotide polymorphism (SNPs) of various species of diatoms.
Abstract:
PURPOSE: A phytoplankton culture apparatus is provided to maintain good condition of organisms to be cultured and to save culture cost. CONSTITUTION: A phytoplankton culture apparatus comprises: a culture container(10) of which part is sunk; a filter unit for preparing pure sea water filled in the culture container; and a stirrer for stirring the inside of the culture container. The culture container is arranged at the floating device in plural. The culture container comprises: a frame(20) for supporting the culture container; a culture tank(30) filled with the culture material and pure seawater; a lid member(40) for preventing inflow of foreign materials or rain into the culture tank.
