摘要: 从微生物学角度‚采用细胞形态学和生理生化分类法‚结合部分细菌16S☞rDNA序列测定结果‚分析了近海养虾场底泥中代谢有机硫和无机硫产H 2 S 细菌的数量、种群结构及其分布特征.发现芽孢杆菌属、盐芽孢杆菌属和微杆菌属的菌株是产H 2 S 的优势菌群‚其它种群细菌产 H 2 S 的作用较小‚硫酸盐还原菌的数量最少.

Abstract: By means of the cellular morphology and the physiologica- l biochemical features‚and combining with partial16S rDNA gene sequencing results of the bacterium‚the amount‚community structure and their distributions of H 2 S-producing bacterium in the sediment of the near -shore shrimp-cultural pond were analyzed.The results indicate that the most of the bacteria population includes the genus of Bacillus‚Halobacillus and Microbium‚while other genus can produce few H 2 S.It is also indicated that sulfate-reducing bacteria is the smallest po-pulation in the sediment.

Key words: near -shore shrimp-cultural pond, sediment, H 2 S pollution, Bacillus, Halobacillus, Microbium, ecological renovation
