Abstract

A thermotolerant l-lactic-acid-producing bacterium was isolated and identified as Bacillus licheniformis TY7. TY7 shows optimum growth at pH 6.5 at 30°C and normal growth up to 65°C. Using nonsterile kitchen refuse at 50°C, the strain produced 40 g/l l-lactic acid with 97% optical activity and 2.5 g/l·h productivity.
