Abstract

The concentration of carbon sources has a significant influence on the growth, carbohydrate uptake and metabolite distribution in Clostridium thermohydrosulfuricum. The growing concentrations of glucose or starch increase the production of ethanol and lactate, the intracellular fructose-1,6-diphosphate (FDP) and the specific activity of lactate dehydrogenase (LDH), but decrease the ethanol/lactate ratio.

摘要

碳源浓度对嗜热栖热梭菌的生长、碳水化合物摄取及代谢物分布有显著影响。葡萄糖或淀粉浓度的增加会提高乙醇和乳酸的产量、细胞内果糖-1,6-二磷酸（FDP）的含量以及乳酸脱氢酶（LDH）的比活性，但会降低乙醇/乳酸的比率。
