| titleOfInvention | Production method of hyaluronic acid |
| abstract | The application discloses a production method of hyaluronic acid, which comprises the following steps: performing activation culture on streptococcus equi; inoculating the activated streptococcus equi into a seed culture medium, and culturing for 8-14h at 35-40 ℃ under the condition of 200-; inoculating Lactobacillus paracasei into a seed culture medium, and culturing at 36-38 deg.C for 12-24 hr; inoculating the streptococcus equi seed liquid and the lactobacillus paracasei seed liquid to a fermentation culture medium, fermenting and culturing for 8-10h under the conditions of 30-33 ℃ and 250r/min and 150-. The streptococcus equi and the lactobacillus paracasei are fermented together, the lactobacillus paracasei can inhibit the activity of hyaluronidase in a fermentation system, and the activity and the yield of hyaluronic acid in fermentation liquor are ensured. |
