Effects of ammonium nitrate (AN) on biomass, pH of fermentation broth (a) and extracellular polysaccharide production (b). Biomass was estimated by determining dry mycelium weight. The extracellular polysaccharide was measured by phenol–sulphuric acid assay. The data were represented as the mean ± SD (n = 3). *P < 0.05, **P < 0.01 was compared with control
