Characterization of lactic acid and acetic acid mutants in batch fermentation

ABSTRACT: Four C. thermocellum DSM-1313 derived strains were assessed using metabolite and DNA microarray tools in order to better understand carbon and electron flow within this organism. C. thermocellum is able to ferment cellulose into its fermentation end products L-lactate, acetate, formate, hydrogen gas, and ethanol, with the latter being the desired end product to be used as biorenewable fuel. In addition to the parent strain (genotype: hpt spo0A), strains with either or both of the genes encoding lactate dehydrogenase (ldh) and phosphate acetyltransferase (pta) deleted were studied. The strains used are a parent strain (M1726: genotype: hpt spo0A), and strains with either the gene encoding lactate dehydrogenase (M1629: hpt spo0A ldh) or phosphate acetyltransferase (M1630: hpt spo0A pta) dele
