Effects of deletion of hasE or scrK on cell growth and HA biosynthesis. a WT and the indicated mutants were grown on solid THY (sucrose+) plates for 24 h, and the colonies were photographed. b The indicated strains were grown in liquid THY (sucrose+) flasks for 24 h, and the cell density was determined by measuring the OD660. c HA produced by the indicated strains grown in liquid THY (sucrose+) flasks for 24 h was determined by the carbazole method. Data (b, c) represents the mean values from three independent experiments
