A thermotolerant bacterium, identified as Bacillus licheniformis, completely utilized 0.1% (w/v) NH4NO3at 30 and 50°C under aerobic condition. The addition of 0.5 mM Fe2+to the NH4NO3medium markedly promoted the utilization of NH4+and NO3-. At 50°C, of total nitrogen originally provided, 24% was tak...
