| Abstract: | The effects of some nutritional conditions,such as yeast extract concentration,feeding glucose as well as ratio of C/N in batch culture,on the production of hyaluronic acid by Streptococcus zooepidemicus H23 were investigated In 5 L jar fermentor batch culture:(1)more than 20*#g/L of yeast extract inhibited the accumulation of HA;(2)production of HA was increased from 4 338*#g/L to 4 837g/L by simply feeding glucose;(3)increasing the concentration of glucose and yeast extract proportionally with constant C/N ratio(12∶1) improved the production of HA It was also found that,glucose consumption and HA production almost stopped under the condition of nitrogen difficiency |
| Keywords: | Streptococcus zooepidemicus hyaluronic acid ratio of C∶N nutritional conditions |
