The fructose diphosphate/phosphate regulation of carbohydrate metabolism in low G+C Gram-positive anaerobes

related to the 'traditional' spore-forming, solvent-producing clostridia (e.g.C. butyricum, C. acetobutylicure), but over 20 other clusters of 'clostridial" organisms have been identified.These clusters include such diverse bacteria as the peptostreptococci, ruminococci, butyrivibrios and eubacteria. FDP/phosphate-dependent lactic acid productionMany species of lactic acid bacteria produce Llactate, but Wolin (1964) noted that the NADHdependent L-lactate dehydrogenase (L-LDH) of the
