Abstract
A stage 4 sporulation mutant of a strain of Bacillus cereus var. alesti fails to synthesize a cortex although all other structural components appear normal. With terminal lysis the spore core as well as the sporangium is lysed. Both the uptake of (45)Ca and the synthesis of dipicolinic acid (DPA) are similar to these activities in the parent strain, but these components (DPA and Ca) are lost to the medium with the drastic lysis. The first stage of diaminopimelic acid incorporation, that into germ cell wall mucopeptide, is intact in the mutant; the second stage, that into cortical mucopeptide, is absent. These biochemical studies as well as phospholipid metabolism and freeze-etch analysis suggest the lesion lies in the outer forespore membrane.
