Inhibition of the development of the spore septum and membranes in Bacillus cereus by beta-phenethyl alcohol.
Remsen, C. C. (Syracuse University, Syracuse, N.Y.), D. G. Lundgren, and R. A. Slepecky. Inhibition of the development of the spore septum and membranes in Bacillus cereus by beta-phenethyl alcohol. J. Bacteriol. 91:324-331. 1966.-The effect of phenethyl alcohol (PEA) upon the initial stages of sporulation in Bacillus cereus was studied with an electron microscope. PEA (0.35%) completely inhibited the development of the spore septum and forespore membranes. Some of the treated cells did form the axial filament of chromatin material regarded as the first stage in sporulation, but this was delayed by 4 to 5 hr compared with untreated cells. The definite effect upon these membrane systems lends support to the belief that the primary site of PEA inhibition may be upon the bacterial membrane. The fine-structure details observed during the initial stages of sporulation in untreated cells were in agreement with the structure published for other Bacillus species.
