It has become increasingly obvious that studies concerning the utility of anaerobic microorganism for biomass conversions are completely limited by our lack of specific basic biochemical, enzymological and genetic information concerning these microorganisms. The focus of this research is toward the cellulase from clostridia which has been shown to be of very high molecular weight and completely different from the well studied fungal systems; towards the enzyme involved in the net formation of acetate in anaerobic bacteria constituting new mechanism of autotrophic CO/sub 2/ fixation; toward the hydrogenase system which appears to involve at least five different types of hydrogenase and two important enzymes of one carbon metabolism, formate dehydrogenase and carbon monoxide dehydrogenase. 70 refs.
