Protein Variants Comment Organism
additional information construction of an engineered Lactobacillus plantarum strain NCIMB 8826, which enables the production of optically pure L-lactate from raw starch for costeffective lactate production. Disruption of the operon encoding lactate racemase (larA-E), which catalyzes the interconversion between D- and L-lactate, completely abolishes D-lactate production. The DELTAldhD DELTAlarA-E mutant produces 87.0 g/l of L-lactate with an optical purity of 99.4%. A plasmid is introduced into the DELTAldhD DELTAlarA-E mutant for the secretion of alpha-amylase from Streptococcus bovis strain 148. The resulting strain produces 50.3 g/l of L-lactate from raw corn starch with a yield of 0.91 g per g of consumed sugar and an optical purity of 98.6% Lactiplantibacillus plantarum

General Information

General Information Comment Organism
malfunction disruption of the operon encoding lactate racemase (larA-E), which catalyzes the interconversion between D- and L-latate, completely abolishes D-lactate production. An engineered Lactobacillus plantarum strain lacking the enzyme is useful in the production of L-lactate from starchy materials Lactiplantibacillus plantarum
