Abstract
Summary Twenty one strains of Tetragenococcus halophilus were investigated for their ecological properties, e.g. growth rate, salt tolerance, pH-dependence and influence of oxygen. All strains tolerated 26% NaCl. The growth rate was optimum at pH 7.5. Anaerobically grown cultures of the type strain achieved a higher growth rate than aerobic cultures. The addition of hematin to aerobic cultures resulted in a reduction in the lag phase and in generation time and a twofold increase in growth yield. Under these growth conditions 12 strains exhibited catalase activity. The composition of the metabolic end products was strongly affected by the growth conditions. Anaerobically grown cultures produced lactate, acetate and formate, whereas acetate was the main product of aerobic cultures.
