Effects of different medium compositions on HA production. The wild type strain ZJU23 was grown in a modified medium based on KB by using different nitrogen sources at a final concentration of 10 g/L (a), carbon sources at a final concentration of 15 g/L (b), metal ions at a final concentration of 1 mM (c), or amino acids at a final concentration of 10 mM (d). The concentration of HA in the individual medium was quantified by HPLC analysis after 72 h of incubation from n = 3 biologically independent samples (mean ± s.e.m.). Different letters indicate significantly different groups (P < 0.05, ANOVA and Fisher's LSD test). Nd not detectable
