Abstract excerpt
Vegetative cells and spores of the colonial morphological mutants of Bacillus subtilis A-50 were studied by electron microscopy. The ultrastructure of vegetative cells from both asporogenic colonial-morphological mutants and those which were capable of forming spores in the presence of high concentrations of nitrogen and carbon sources with a decreased activity and a modified spectrum of serine proteases differed...
