摘要

在研究的3株乙酰丁酸梭菌NRRL 592、NCIB 619和ATCC 824中，只有后者具有NADH:红霉素氧化还原酶活性。我们报道该酶的生物合成率根据生长阶段和培养基组成在1 ~ 50的比例上下波动。这些变化反映了一种适应细菌代谢的调节模式。

[Effect of growth phase and composition of the medium on the rate of biosynthesis of NADH: rubredoxin oxidoreductase in Clostridium acetobutylicum].

Among the three strains of Clostridium acetobutylicum we investigated: NRRL 592, NCIB 619 and ATCC 824, only the last was shown to contain a NADH: rubredoxin oxidoreductase activity. We report that the biosynthesis rate of this enzyme fluctuated in the proportions of 1 to 50 according to the growth phase and medium composition. These variations reflect a mode of regulation adjusted to the metabolism of bacteria.
