Effect of three factors on lignin degradation rate of E. billingiae QL-Z3. Medium Number: 0, 2.0 g/L lignin, pH = 7, tryptone (initial medium); 1, 1.0 g/L lignin, pH = 7, (NH4)2SO4; 2, 1.0 g/L lignin, PH = 5, NaNO3; 3, 1.0 g/L lignin, pH = 9, tryptone; 4, 1.5 g/L lignin, pH = 9, NaNO3;5, 1.5 g/L lignin, pH = 5, (NH4)2SO4; 6, 1.5 g/L lignin, pH = 7, tryptone; 7, 2.0 g/L lignin, pH = 5, tryptone; 8, 2.0 g/L lignin, pH = 7, NaNO3; 9, 2.0 g/L lignin, pH = 9, (NH4)2SO4. Average values of three replicates are shown with the standard errors of the mean shown as error bars. Each experimental group was conducted in triplicate
