Fig. 3From: Construction of efficient Streptococcus zooepidemicus strains for hyaluoronic acid production based on identification of key genes involved in sucrose metabolismEffects of overexpression of scrA or scrB (scrA-OP or scrB-OP) on the growth and HA biosynthesis. a The indicated strains were grown in liquid THY (sucrose+) flasks for 24 h and cell density was determined by measuring the OD660. b HA produced by the indicated strains grown in liquid THY (sucrose+) flasks for 24 h was determined by the carbazole method. Data (a, b) represents the mean values from three independent experimentsBack to article page
