Stoichiometry of glucose and starch splitting by strains of amylolytic bacteria from the rumen and anaerobic digester

The stoichiometry of glucose and starch splitting by the amylolytic bacteria Streptococcus bovis, Selenomonas ruminantium, Butyrivibrio fibrisolvens, Eubacterium ruminantium and Clostridium sp. was followed. There were many differences in the ratios of metabolites and in growth yields, as well as in the cell composition, between the growth on glucose and starch. The bacteria employ different nutritional strategies with respect to both energy sources.
