abstract：:Growth inhibition by isoleucine hydroxamate in Serratia marcescens was significantly enhanced by adding valine plus leucine and by using glycerol as the carbon source. Isoleucine hydroxamate-resistant mutants were isolated under conditions in which growth inhibition was enhanced. One of the mutants, strain GIHVLr2179,...
