The conversion of biomass of fuels and chemical feedstocks by microbial fermentation offers the potential of solving two of today's important problems: waste accumulation and exhaustion of fossil fuels. Microorganisms with the capabilities of converting biomass components such as cellulos and hemicellulose to chemicals and fuels in a single step are of particular interest. One such microorganism is Clostridium thermocellum, a thermophilic anaerobe which degrades cellulose to ethanol and organic acids. For efficient industrial use, the cellulolytic capacity of this strain must be improved by genetic means. Spontaneous and UV irradiation-induced auxotrophic mutants of Clostridium thermocellum, an anaerobic cellulolytic thermophile, were isolated after penicillin enrichment in a chemically defined medium.
