Effects of Rice-Washing Water on the Hyaluronic Acid Production of StreptococcusThermophilus
Hyaluronic acid (HA), one of the most potential biological materials, is increasingly widely used in pharmaceutical and cosmetics nowadays. Hyaluronic acid was produced commercially from rooster combs and the fermentation of Streptococci groups A and C. In order to contribute to the safety and cheap hyaluronic acid for human, we used rice-washing water as medium to culture Streptococcus thermophilus MR10 which was detected as hyaluronic acid production source isolated in fermented foods in Vietnam. This is the first report pointing the the effects of cheap rice-washing water on the HA production of Streptococcus thermophilus. In the medium containing ricewashing water, Streptococcus thermophilus produced HA better than the usual MRS medium for Streptococcus thermophilus growth.
