Abstract:This study aimed to synthesize hyaluronic acid (HA) using a non-pathogenic, recombinant bacterial host, specifically Bacillus subtilis 1A752. The hyaluronic acid synthase (HAS) gene, hasA, originally isolated from Streptococcus equi subsp. zooepidemicus, was introduced into B. subtilis 1A752. This host strain already harbors tuaD, gtaB, and gcaD genes, which are functional analogues to the Streptococcus genes hasB, hasC, and hasD, respectively. The hasA operon was amplified from genomic DNA of S. zooepidemicus… Show more
