Abstract

SUMMARY

Antagonism by an antibiotic-producing strain (S6) against other bacteria was studied semi-quantitatively on solid media and quantitatively in liquid batch culture. Parallel experiments were performed with a similar but non-antibiotic producing strain (S6). On solid media strain S6 in the logarithmic growth phase unilaterally inhibited members of all gram-positive species tested, whereas S6 had no effect. In liquid media, more complex interactions were observed, including mutual and reversed antagonisms. The relevance of these findings to the ecology of human skin is discussed.
