Abstract

Both hard (mostly oak) and soft (pine and fir) wood sawdust were fermented by mixed cultures of anaerobic bacteria with concomitant methane production. A greater lag in methane production occurred with soft than with hard wood. Arabinose, rhamnose, and xylose stimulated mixed culture methanogenesis in the presence of added methane precursors (acetate, formate, CO2 and H2). Xylose retarded methane production in pure cultures of Methanobacterium formicicum. Alcoholic extracts of both woods inhibited methane production, and the greater amounts of these in coniferous wood may explain the lag.

Microbial production of methane from wood and inhibition by ethanol extracts of wood

Journal Article Mink, R; Dugan, P - Ohio J. Sci.; (United States)

Mixed cultures of anaerobic bacteria fermented both coniferous and deciduous wood sawdust concomitant CH4 production. A consistently greater lag in methanogenesis was observed on coniferous than on deciduous wood. Arabinose, glucose, galactose, mannose, rhamnose, and xylose when added to enrichment cultures had either no effect or a slight stimulation of CH4 production in the absence of added CH4 precursors (AcO-HCO2-, CO2, and H). In the presence of added precursors arabinose, rhamnose, and xylose stimulated mixed culture methanogenesis, but xylose retarded methanogenesis in pure cultures of Methanobacterium formicicum. Alcohol extracts of either deciduous or coniferous wood were inhibitory to methanogenesis frommore »« less
Kinetics of formate metabolism in Methanobacterium formicicum and Methanospirillum hungatei

Journal Article Schauer, N; Brown, D; Ferry, J - Appl. Environ. Microbiol.; (United States)

The kinetics of formate metabolism in Methanobacterium formicicum and Methanospirillum hungatei were studied with log-phase formate-grown cultures. The progress of formate degradation was followed by the formyltetrahydrofolate synthetase assay for formate and fitted to the integrated form of the Michaelis-Menten equation. The Km and Vmax values for Methanobacterium formicicum were 0.58 mM formate and 0.037 mol of formate/h/g (dry weight), respectively. The lowest concentration of formate metabolized by Methanobacterium formicicum was 26 muM. The Km and Vmax values for Methanospirillum hungatei were 0.22 mM and 0.044 mol of formate/h/g (dry weight), respectively. The lowest concentration of formate metabolized by Methanospirillummore »« less
Influence of corrinoid antagonists on methanogen metabolism

Journal Article Kenealy, W; Zeikus, J - J. Bacteriol.; (United States)

Iodopropane inhibited cell growth and methane production when Methanobacterium thermoautotrophicum, Methanobacterium formicicum, and Methanosarcina barkeri were cultured on H/sub 2/-CO/sub 2/. Iodopropane (40 ..mu..M) inhibited methanogenesis (30%) and growth (80%) when M. barkeri was cultured mixotrophically on H/sub 2/-CO/sub 2/-methanol. The addition of acetate to the medium prevented the observed iodopropane-dependent inhibition of growth. Cultivation of M. barkeri on H/sub 2/-CO/sub 2/-methanol in bright light also inhibited growth and methanogenesis to a greater extent in the absence than in the presence of acetate in the medium. Acetate was the only organic compound examined that prevented iodopropane-dependent inhibition of one-carbon metabolismmore »« less
Control of interspecies electron flow during anaerobic digestion: significance of formate transfer versus hydrogen transfer during syntrophic methanogenesis in flocs. [Methanobacterium formicicum; Desulfovibrio vulgaris]

Journal Article Thiele, J; Zeikus, J - Appl. Environ. Microbiol.; (United States)

Microbial formate production and consumption during syntrophic conversion of ethanol or lactate to methane was examined in purified flocs and digestor contents obtained from a whey-processing digestor. Formate production by digestor contents or purified digestor flocs was dependent on CO/sub 2/ and either ethanol or lactate but not H/sub 2/ gas as an electron donor. Floc preparations accumulated fourfold-higher levels of formate (40 ..mu..M) than digestor contents, and the free flora was the primary site for formate cleavage to CO/sub 2/ and H/sub 2/ (90 ..mu..M formate per h). Inhibition of methanogenesis by CHCl/sub 3/ resulted in formate accumulation andmore »« less
One carbon metabolism in anaerobic bacteria: Regulation of carbon and electron flow during organic acid production

Technical Report Zeikus, J; Jain, M

The project deals with understanding the fundamental biochemical mechanisms that physiologically control and regulate carbon and electron flow in anaerobic chemosynthetic bacteria that couple metabolism of single carbon compounds and hydrogen to the production of organic acids (formic, acetic, butyric, and succinic) or methane. The authors compare the regulation of carbon dioxide and hydrogen metabolism by fermentation, enzyme, and electron carrier analysis using Butyribacterium methylotrophicum, Anaeroblospirillum succiniciproducens, Methanosarcina barkeri, and a newly isolated tri-culture composed of a syntrophic butyrate degrader strain IB, Methanosarcina mazei and Methanobacterium formicicum as model systems. To understand the regulation of hydrogen metabolism during butyrate productionmore »« less
