ABSTRACT:
Thermophilic microorganismBacillus coagulansstrain SIM-7 DSM 14043 for the production of L(+)-lactate from fermentable sugars, including dextrines and starch. The temperature of cultivation is 53–65° C. being the optimal. The final concentration of L(+)-lactate in fermentation is 12% with the yield of 95%. The cultivation of this strain of microorganism is possible without the high-temperature sterilization of equipment and media. Using cereal flour as the source of fermentable sugars, the need of the strain of the microorganism for mineral and nitrogen salts will be covered by the compounds present in the cereals.
