Effects of medium and culture conditions on folate production by Streptococcus thermophilus BAA-250.

The present study was conducted to investigate the effects of culture conditions on folate production by Streptococcus thermophilus BAA-250. Lactose (3g/L) and yeast extract (20g/L) were found to be the more suitable carbon and nitrogen sources for folate production by S. thermophilus BAA-250....
