Abstract

Summary: The function(s) of the peptide antibiotic, gramicidin S, in its producer, Nagano, was investigated. Particular attention was paid to the possible role of gramicidin S in sporulation and spore properties. Sporulation was similar in both the gramicidin S-producing parental strain and a gramicidin S-negative mutant of this strain. Mature parental and mutant spores were equally resistant to UV irradiation, solvents (reported previously) and heat. Thus, the lack of gramicidin S synthesis impairs none of these properties. Contrary to results reported by others, we also found no difference in heat resistance between spores of ATCC 8185 and its linear gramicidin-negative mutant, Ml.
