Microbial production of methane from wood and inhibition by ethanol extracts of wood
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 from either mixed cultures or from M. formicicum.
