胶州湾潮间带和沿岸区硫酸盐还原菌含量分布

Distribution of sulphate reducing bacteria in the intertidal and coastal zones of Jiaozhou Bay

用 Ｍ Ｐ Ｎ 法对胶州湾潮间带和沿岸区的硫酸盐还原菌（ 缩写为 Ｓ Ｒ Ｂ） 含量作了研究，结果表明表层沉积物的 Ｓ Ｒ Ｂ 含量大约是４１ ×１０７ 个细胞／ｇ ，波动范围较大。水中的 Ｓ Ｒ Ｂ 含量约２５ ×１０２／ｍｌ。分析了 Ｓ Ｒ Ｂ 含量的分布状况，发现调查区内的 Ｓ Ｒ Ｂ 含量基本上呈现出北高南低、西高东低之势，即工业区、港口区的高于海水浴场、海滨旅游区的。证实了生活废弃物的排放致其环境 Ｓ Ｒ Ｂ 含量特高。 Ｓ Ｒ Ｂ 含量分布状况大体上与以往所测环境污染状况一致。对虾养殖池的 Ｓ Ｒ Ｂ

The content of sulphate reducing bacterial (SRB) in the intertidal and coastal zones of Jiaozhou Bay was researched by MPN method. The results shown that content of SRB in the surface layer sediments averaged about 4 1×10 7 cells/g, and its fluctuation was rather big. The concentration of SRB in the water about 2 5×10 2 cells/ml. The distribution of SRB was analysed and found out that the tendacy of the contents of SRB was high in the north and west areas, and low in the south and east areas, i.e. concentration in the industrial or harbour areas were higher than in the bathering beaches and tourist areas. The specially high content of SRB in the environment was induced by the discharge of domestic waste. The distribution of the SRB content was roughly consistent with that of the environmental pollution confirmed early. The SRB contents in the ponds for culturing shrimp were similar to those reported previouly.
