Microbial resolution of dl-glyceric acid for l-glyceric acid production with newly isolated bacterial strains

To produce l-glyceric acid (l-GA) from dl-GA, microbial resolution was investigated using newly isolated bacterial strains capable of enantiospecific degradation of d-GA. Strains GA3R and GA72P, identified as Serratia and Pseudomonas species, respectively, exhausted d-GA within 72 h, resulting in production of l-GA with enantiomeric purity ≥89%.
