Abstract
Mutants deficient in different enzymes of the citric acid cycle can be subdivided into two groups according to the frequency at which they produce heat-resistant spores in nutrient sporulation medium. However, the majority of cells can develop in this medium only to the axial filament stage I of sporulation; aconitase and isocitrate dehydrogenase mutants need the addition of glutamate to reach this stage.
摘要
柠檬酸循环中不同酶缺乏的突变体，根据它们在营养芽孢形成培养基中产生耐热孢子的频率可分为两组。然而，大多数细胞在这种培养基中只能发育到芽孢形成的轴向丝阶段I；乌头酸酶和异柠檬酸脱氢酶突变体需要添加谷氨酸才能达到这个阶段。
