Abstract
Free amino acids, dipicolinic acid, and unidentified small molecules were released early in Bacillus spore germination before hydrolysis of the peptidoglycan cortex, but adenine nucleotides and 3-phosphoglycerate were not. These results indicate that early in germination there is a major selective change in the permeability of the spore's inner membrane.
摘要
在芽孢杆菌孢子萌发过程中，游离氨基酸、吡啶二羧酸和未鉴定的小分子在肽聚糖皮层水解之前就已释放，但腺嘌呤核苷酸和3-磷酸甘油酸则没有。这些结果表明，在萌发早期，孢子内膜的通透性发生了重大的选择性变化。
