  • Patent number: 7183088
    Abstract: Thermophilic microorganism Bacillus coagulans strain 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.

  • Publication number: 20060154350
    Abstract: The invention relates to the use of lactic acid and its esters produced upon microbiological fermentation of organic substances, particularly cereal starch, for producing biodegradable lactic acid polymers and use of the biodegradable polymer produced using such a technique. The areas of application of the invention include food processing and chemical technology. The fields of usage of the invention include the production of starch, phytoprotein, lactic acid and its derivatives, including its salts, esters and biodegradable polymer (PLA).
