Acetate was shown to improve glucose fermentation in Lactococcus lactis deficient in lactate dehydrogenase. 13C and 1H nuclear magnetic resonance studies using [2-13C]glucose and [2-(13)C]acetate as substrates demonstrated that acetate was exclusively converted to ethanol. This novel pathway provides an alternative route for NAD+ regeneration in the absence of lactate dehydrogenase.
已表明乙酸盐可改善乳酸脱氢酶缺陷的乳酸乳球菌中的葡萄糖发酵。使用[2-¹³C]葡萄糖和[2-(¹³)C]乙酸盐作为底物的¹³C和¹H核磁共振研究表明,乙酸盐仅转化为乙醇。在缺乏乳酸脱氢酶的情况下,这条新途径为NAD⁺再生提供了一条替代途径。
