Whey fermentation by Anaerobiospirillum succiniciproducens for production of a succinate-based animal feed additive

摘要: Anaerobic fermentation processes for the production of a succinate-rich animal feed supplement from raw whey were investigated with batch, continuous, and variable-volume fed-batch cultures Anaerobiospirillum succiniciproducens. The highest succinate yield, 90%, was obtained in process comparison to 80% yield batch cultivation mode. In continuous culture, productivity 3 g/liter/h, 60%. Under conditions excess CO2, more than 90% whey-lactose consumed, an end product ratio 4 1 acetate. limited lactose only partially consumed lactate major product, lower levels ethanol, succinate, When succinic acid this added rumen fluid, it completely by mixed population decarboxylated propionate on molar basis. formed under which contained mainly organic acids cells, could potentially be used as supplement.
