Abstract
Carbon balances have been obtained for the fermentation of glucose, xylose, pyruvic acid, and mannitol by Aerobacillus polymyxa. The chief products from glucose are 2,3-butanediol, ethanol, carbon dioxide, and hydrogen; in addition small amounts of acetic acid and acetoin are formed. In glucose fermentations under the conditions used the butanediol: ethanol ratio is about 1:1. The products of xylose fermentation are very similar, although the butanediol: ethanol ratio is shifted in favour of ethanol. From pyruvic acid the chief end-products are acetoin, acetic acid, carbon dioxide and hydrogen with almost no butanediol and ethanol production. In the fermentation of mannitol a large amount of lactic acid is produced, while butanediol production is markedly decreased, the butanediol: ethanol ratio being 1:7.
