✦ Synopsis
Certain Bacillus brevis strains produce gramicidin S (GS) during sporulation, and germination of such spores is delayed at the stage of outgrowth by endogenous or exogenous GS. Claims have been made that the transition from germinating spores into vegetative cells is dependent on GS destruction. We observed no such destruction of either exogenous or endogenous GS. Thus, in our hands, the "recovery" of the inhibited germinating spores must be dependent on something other than GS elimination.
