[The composition and distribution of some kinds of anaerobic microorganisms in Yinqion basin].
Under the strictly anaerobic conditions, the population of Sulfate-reducing bacteria, fermentative bacteria and methanogenic bacteria of serial samples got from erect sections of different Sedimentary of Yingqiong basin (a typical marine sedimentary environment) were measured by MPN method. The morphology of different kinds of bacteria and the metabolic types of methanogen and methanogenic activity were observed. The relation between population of bacteria and some indexes were compared. The results show that SRB present in all of the samples. The distribution of SRB and fermentative bacteria have no interrelation with the depth of samples but SRB has interrelation with the SO(4)2- concentration, and fermentative bacteria has negative interrelation with the contents of organic matter. Two kinds of methanogen present in all of the samples. They belong to Methanobacterium and Methanococcus, respectively. Their types of nutriment are H2/CO2.
