During an investigation of the parameters controlling mutations in Bacillus subtilis we observed that this bacterium exhibits a transient growth requirement for two nonessential amino acids (glutamic acid and isoleucine) during a type of postexponential growth on a minimal medium.
在对控制枯草芽孢杆菌突变的参数进行研究期间,我们观察到,在基本培养基上进行一种指数后期生长时,这种细菌对两种非必需氨基酸(谷氨酸和异亮氨酸)表现出短暂的生长需求。
