Resistance of Streptococcus lactis Mutants to β-Lactam Antibiotics
Minimal inhibitory concentration and minimal bactericidal concentrations of penicillin and other β-lactam antibiotics were determined for Streptococcus lactis in milk and trypteine soy broth. The values were always higher in milk than in broth. Minimal inhibitory concentration of penicillin was high...
