摘要
对黄海冷水团附近海域的沉积物进行了富集、荧光显微镜观察、电镜观察,并对其中大小均匀、形状规则的高密度颗粒进行了能谱分析。结果显示,在黄海冷水团附近有趋磁细菌和磁小体的存在。
Because of the unique characteristics of magnctotactic bacteria and bacterial magnetosomes, they have great application future in materials, biomedical and so on. Isolation and cultivation of these bacteria are very difficult due to their life styles such as microaerophilic or anaerobic. Studies on ecological distribution of magnetotactic bacteria are helpful for their isolations. In this rescarch, sediment collected from site near cold water mass of the Yellow Sea was enriched, and rust-like particles were observed in the enrichmental solutions. Fluorescence microscopic examination and transmission electron microscopic observation on the en.richmental solutions were investigated. The energy dispersive X-ray spectra of the narrow-in-size and uniform-shaped high dense particles appeared in enrichmental solutions were also done. Results indicated that magnetotactic bacteria and magnetosomes existed in sediments from the Yellow Sea cold water mass.
