[Species composition of methane bacteria in fermented cattle manure]
Abstract
The species composition of methanogenic bacteria taking part in thermophilic and mesophilic methanogenesis of cattle manure was studied. In both cases methanogenic bacteria belonging to the genera Methanosarcina, Methanothrix, and Methanobacterium were identified. The description of Methanosarcina thermophila, Methanosarcina mazei, Methanothrix thermoacetophila and Methanobacterium thermoformicicum are given. The methanogenic bacteria are able to utilize all the methane procursors known to date. In methanetanks fermenting cattle manure acetate-utilizing methanogenic bacteria play the leading role in contrast to the rumen microflora.
