Abstract
Keynan, A. (University of Wisconsin, Madison), W. G. Murrell, and H. O. Halvorson. Germination properties of spores with low dipicolinic acid content. J. Bacteriol. 83:395-399. 1962.-When the dipicolinic acid content of spores of Bacillus cereus strain T is reduced from 7.5 to 2 or 3%, the spores germinate spontaneously after heat activation and are sluggish in their response to l-alanine and other germination agents. Only germination initiated by calcium dipicolinic acid is unaffected. l-Alanine-induced germination is stimulated by exogenous dipicolinic acid. These results support the hypothesis that endogenous dipicolinic acid regulates the l-alanine-triggered germination.

凯南，A.（威斯康星大学麦迪逊分校），W.G. 默雷尔，以及H.O. 哈尔沃森。低吡啶二羧酸含量芽孢的萌发特性。《细菌学杂志》83:395 - 399。1962年。——当蜡样芽孢杆菌T菌株芽孢的吡啶二羧酸含量从7.5%降至2%或3%时，芽孢在热激活后会自发萌发，并且对L - 丙氨酸和其他萌发剂的反应迟缓。只有由吡啶二羧酸钙引发的萌发不受影响。外源吡啶二羧酸会刺激L - 丙氨酸诱导的萌发。这些结果支持了内源性吡啶二羧酸调节L - 丙氨酸引发的萌发这一假说。
