Presence of an unusual methanogenic bacterium in coal gasification waste.

摘要: Methanogenic bacteria growing on a pilot-scale, anaerobic filter processing coal gasification waste were enriched in mineral salts medium containing hydrogen and acetate as potential energy sources. Transfer of the enrichments to methanol resulted initial growth strain Methanosarcina barkeri, but eventually small cocci became dominant. The produced methane exhibited typical fluorescence methanogenic bacteria. They grew presence cell wall synthesis-inhibiting antibiotics d-cycloserine, fosfomycin, penicillin G, vancomycin well kanamycin, an inhibitor protein synthesis eubacteria. optimal temperature was 37°C, doubling time 7.5 h. lysed after reaching stationary phase. bacterium poorly with source failed grow acetate. Morphologically, coccus shared similarities sp. Cells 1 μm wide, thick cross-wall formation, formed tetrads. Packets cysts not formed. Images
