Effect of pH on HA production by strain H15 in the modified medium. The production of HA was assessed at various pH values by adjusting the medium with 1 N HCl and 1 N NaOH. Values are shown ± SD of triplicate measurements from two independent experiments. Different letters on the bars of HA concentrations determined by HPLC method (free letters), turbidimetric method (in small squares) and carbazole method (in small circles) indicate significant differences (LSD, P ≤ 0.05) at different pH values
