application of new technologies breeding high-yielding strains

Strain is the lifeblood fermentation industry, an excellent production strain is to improve product yield and quality And economic protection. Thus, on the one hand should be calcium lactate  acid-producing wild type strain Screening and development work; hand should the traditional mutation breeding techniques and molecular biology Breeding techniques combined with effective, targeted breeding to produce L-lactic acid producing strain excellent. With When vigorously and development of genetically engineered bacteria to build, and large-scale production applications. Excellent Of the fermentation process, reduce production costs: for medium optimization screening studies, the use of sugar Scrap cheap raw materials, the establishment of efficient, low-cost L-lactic fermentation and extraction methods And reduce production costs. Sodium lactate fermentation equipment and extraction process: the production of lactic acid fermentation, the next Tour extraction process accounts for a large percentage of the cost, so to strengthen downstream processes and equipment research Research development. Design new fermentation equipment, effective utilization of advanced in-situ separation technology,Integrated molecular distillation and membrane separation technology to improve the separation process, reduce product extraction costs, improve Benefits.
