| Abstract: | Magnetotactic bacteria have become a hot spot of research in microbiology attracting inten-sive interest of researchers in multiple disciplinary fields. However, the studies were limited in few fas-tidious bacteria. The objective of this study aims at isolating new marine magnetic bacteria and better comprehension of magnetotactic bacteria. In this study, an aerobic magnetotactic bacterium YSC-1 was isolated from sediments in the Yellow Sea Cold Water Mass (YSCWM). In TEM, magnetic cells have one or several circular magnetosomes in diameter of 100nm, and consist of Fe and Co shown on energy dis-persive X-ray spectrum. The biological and physiological characteristics of this bacterium were also de-scribed. The colour of YSC-1 colony is white in small rod. The gram stain is negative. Results showed that Strain YSC-1 differs from microaerophile magnetotactic bacteria MS-1 and WD-1 in biology. |
