Genetically engineered wine yeast produces a high concentration of L-lactic acid of extremely high optical purity.

چکیده
For mass production of lactic acid, we newly constructed a transgenic wine yeast strain that included six copies of the bovine L-lactate dehydrogenase gene on the genome. On fermentation in inexpensive cane juice-based medium, L-lactate production of this recombinant reached 122 g/liter and the optical purity was 99.9% or higher.

Comparison of Lactic Acid Isomers Produced by Fungal and Bacterial Strains
Many organisms produce lactic acid by fermentation, but most industrially important strains are from the genus Lactobacillus and Rhizopus oryzae. L(+)-Lactic acid is the only optical isomer for use in pharmaceutical and food industries because human body is only adapted to assimilate this form. In this research, six strains of Lactobacillus and four strains of R. oryzae (known as high producer)...
متن کاملIsolation of thermophilic L-lactic acid producing bacteria showing homo-fermentative manner under high aeration condition.
By applying non-sterile open fermentation of food waste, various thermotolerant l-lactic acid-producing bacteria were isolated and identified. The predominant bacterial isolates showing higher accumulation of l-lactic acid belong to 3 groups of Bacillus coagulans, according to their 16S rRNA gene sequence similarities. B. coagulans strains M21 and M36 produced high amounts of l-lactic acid of h...
متن کاملEfficient synthesis of L-lactic acid from glycerol by metabolically engineered Escherichia coli
BACKGROUND Due to its abundance and low-price, glycerol has become an attractive carbon source for the industrial production of value-added fuels and chemicals. This work reports the engineering of E. coli for the efficient conversion of glycerol into L-lactic acid (L-lactate). RESULTS Escherichia coli strains have previously been metabolically engineered for the microaerobic production of D-...
متن کاملGenetic engineering of Candida utilis yeast for efficient production of L-lactic acid.
Polylactic acid is receiving increasing attention as a renewable alternative for conventional petroleum-based plastics. In the present study, we constructed a metabolically-engineered Candida utilis strain that produces L-lactic acid with the highest efficiency yet reported in yeasts. Initially, the gene encoding pyruvate decarboxylase (CuPDC1) was identified, followed by four CuPDC1 disruption...
متن کاملMetabolic engineering of malolactic wine yeast.
Malolactic fermentation is essential for the deacidification of high acid grape must. We have constructed a genetically stable industrial strain of Saccharomyces cerevisiae by integrating a linear cassette containing the Schizosaccharomyces pombe malate permease gene (mae1) and the Oenococcus oeni malolactic gene (mleA) under control of the S. cerevisiae PGK1 promoter and terminator sequences i...
