Methanogenesis from acetate: a nonmethanogenic bacterium from an anaerobic acetate enrichment.
A methanogenic acetate enrichment was initiated by inoculation of an acetate-mineral salts medium with domestic anaerobic digestor sludge and maintained by weekly transfer for 2 years. The enrichment culture contained a Methanosarcina and several obligately anaerobic nonmethanogenic bacteria. These latter organisms formed varying degrees of association with the Methanosarcina, ranging from the ...
متن کاملBioenergetics of methanogenesis from acetate by Methanosarcina barkeri.
Methane formation from acetate by resting cells of Methanosarcina barkeri was accompanied by an increase in the intracellular ATP content from 0.9 to 4.0 nmol/mg of protein. Correspondingly, the proton motive force increased to a steady-state level of -120 mV. The transmembrane pH gradient however, was reversed under these conditions and amounted to +20 mV. The addition of the protonophore 3,5,...

متن کاملSelective inhibition by 2-bromoethanesulfonate of methanogenesis from acetate in a thermophilic anaerobic digestor.
The effects of 2-bromoethanesulfonate, an inhibitor of methanogenesis, on metabolism in sludge from a thermophilic (58 degrees C) anaerobic digestor were studied. It was found from short-term experiments that 1 mumol of 2-bromoethanesulfonate per ml completely inhibited methanogenesis from CH(3)COO, whereas 50 mumol/ml was required for complete inhibition of CO(2) reduction. When 1 mumol of 2-b...
متن کاملSystematic enrichment analysis of microRNA expression profiling studies in endometriosis
Objective(s): The purpose of this study was to conduct a meta-analysis on human microRNAs (miRNAs) expression data of endometriosis tissue profiles versus those of normal controls and to identify novel putative diagnostic markers. Materials andMethods: PubMed, Embase, Web of Science, Ovid Medline were used to search for endometriosis miRNA expression profiling studies of endometriosis. The miRN...
