摘要: A thermophilic Bacillus coagulans WCP10-4 with tolerance to high concentration of glucose was isolated from soil and used produce optically pure l-lactic acid starch. In batch fermentation at pH 6.0, 240 g/L completely consumed giving 210 a yield 95 % productivity 3.5 g/L/h. simultaneous saccharification 50 °C without sterilizing the medium, 200 corn starch producing 202.0 acid. To best our knowledge, this strain shows highest osmotic among strains ever reported for lactic production. This is first report production under non-sterilized condition.
