Elucidation of control mechanism of spore germination in microorganisms by self-germination inhibitors of actinomycetes.

从天蓝色链霉菌中分离得到4种杀菌素。它们的萌发抑制活性和孢子中的含量表明，细菌杀菌素具有自萌发抑制作用。对病毒链霉菌的复检表明，主要的自萌发抑制物是一种乙酸乙酯溶解的中性物质。灰色链霉菌也产生了类似的抑制剂。

Four germicidins were isolated from Streptomyces coelicolor. Their germination inhibitory activity and contents in spores revealed that germicidins function as self-germination inhibitors. Reexamination in S. viridochromogenes indicated that the major self-germination inhibitor was found to be an EtOAc-soluble neutral substance. The similar inhibitor was also produced by S.griseus.
