A new mesophilic strain of Methanothrix, strain FE, was highly purified from the sludge of an anaerobic digester after enrichment on sodium acetate and is described. Strain FE was compared with other strains of Methanothrix, Methanothrix soehngenii strain Opfikon(T) (= DSM 2139(T) (T = type strain) and Methanothrix concilii strain GP6(T) (= DSM 367...

Studies on immunological relationships among Methanosarcina genus using immunofluorescence and immunoprecipitation showed that a common antigen can be extracted by shaking in aqueous phase. This antigen was purified from Methanosarcina mazei. The protein had a molecular weight of 283400 daltons with three subunits, =68000, =43200 and =30500. It con...

... 54 Cross-reactions of the probes within some genera are possible and represent one of the drawbacks for this technique. 55 Methanogenesis, a limiting step, directly connected to the amount of methane produced, is an industrially interesting phase in the biogas production process. Several studies based on molecular biology have been made upon the structure of methanogenic communities in the biogas process as bio-molecular approach introduces useful bioindicators for early diagnosis of any unbalance in the microbial community. ...
