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.
