Abstract
Cells of S. aureus, strain S-6, can grow in the presence of 100 .mu.g of cerulenin/ml if the basal medium is supplemented with certain saturated or unsaturated fatty acids. The production of enterotoxin B (SEB) is markedly influenced by the ratio of saturated to unsaturated fatty acid and by the melting point of the unsaturated fatty acid supplement. Possibly, a certain degree of membrane fluidity promotes maximum SEB production and greater or lesser degrees of membrane fluidity prohibit substantial SEB formation but fail to affect final growth density.This publication has 0 references indexed in Scilit:
