โœฆ Synopsis

Assimilation of ammonium by the obligate anaerobic bacterium Closlridium acetobufylicirm was accomplished by the pathway: Glutamine synthetase/glutamate synthase. C. ace/ohutylicum also contained an asparagine synthetase, but no glutamate dehydrogenase activity was detected. The glutamine synthetase was partially repressed by addition of large amounts of ammonium chloride and/or casaminoacids to the medium, while the biosynthesis of the other enzymes was not regulated by the extracellular concentration of ammonium.

Addition of ammonium salts to N 2 fixing continuous cultures of Clostridium pasteurianum caused immediate stop of nitrogenase synthesis, while the levels of glutamine synthetase, glutamate dehydrogenase and asparagine synthetase remained constant. No evidence for an interconversion of the glutamine

Metabolic flux analysis was used to investigate the roles of the acid formation pathways in Clostridium acetobutylicum. The acid formation pathways were revealed to serve different roles in wildtype fermentations than previously expected. Specifically, enzymes known to catalyze butyrate formation we
