All strains grew facultatively anaerobically
and produced, under anaerobic growth conditions,
equal amounts of D- and L-lactate from
glucose. The pH of a peptone-yeast extractglucose
broth was lowered from 6.8 to 4.2 after 2
days of growth under anaerobic conditions.
All strains grew well at 15 and 45°C and at
NaCl concentrations up to 15%. All strains
reduced nitrate and produced acetoin. All failed
to produce coagulase and to exhibit hemolysin
activity. All‘ were negative for the oxidase test
and resistant to 50 kg of lysozyme per ml. Their
growth was inhibited by 200 pg of lysostaphin or
1.6 pg of novobiocin per ml.
