Abstract The budding, prosthecate, gas vacuolate bacterium, Ancalomicrobium adetum, ferments sugars including glucose and lactose to produce acid and gas. Glucose is fermented by a mixed acid fermentation resulting in the formation of formic, acetic, lactic, and succinic acids, ethanol, carbon dioxide, and hydrogen. These are the same products produced by the enteric bacterium, Escherichia coli. Thus, these two bacteria which are currently classified in very different groups, may be evolutionarily related to one another. Alternatively it could be argued that the mixed acid fermentation arose more than once in evolution or that the genes of this major catabolic pathway can be transferred laterally among unrelated bacteria.
