Thermoanaerobacter species degrade branched-chain amino acids to a mixture of their corresponding branched-chain fatty acids and alcohols in the presence of thiosulfate; only acid formation occurred when Thermoanaerobacter strains were cultivated in co-culture with a hydrogenotrophic methanogen. Increased pH<SUB>2</SUB> at high liquid-gas phase ratios increases the relative concentration of branched-chain alcohol.
