降解四氯乙烯厌氧菌的分离和特征

从降解四氯乙烯沼气污泥富集培养物中分离得到4株厌氧菌，其中2株为弧菌（Vibrio），其细胞弧状，分别端单生，丛生鞭毛；1株是杆菌（Bacillus），其细胞杆状，G－，无鞭毛和芽孢；1株为甲烷八叠球菌（Methanosarcina），其细胞球状，成堆排列．4株菌均可以甲醇为碳源，并具有不同强度降解四氯乙烯的活性．

ISOLATION AND CHARACTERIZATION OF ANAEROBICBACTERIA FOR TETRACHLOROETHYLENE DEGRADATION

: Four strains of strictly anaerobic bacteria were isolated from methanogenic sewage sludge enrichment culture of tetrachlomethylene degradation. Two strains are Vibrio, which are provided by a polar flagellum; one is Bacillus , the cells are rod shaped and gram-negative, non-spore-forming und flagellum; the otheris Methanosarcina , its cells are irregular cooci and to packform . The four isolated strains are able to take methanol as carbon sources and possess different activities of the tetrachloroethlene degradation .
