Effect of nitrogen source on bacterial growth and zeamine production by D. zeae EC1.

Note: Each inorganic nitrogen source was tested at 15 mM/L (Concentration of nitrogen molecules) and amino acid was tested at 1 g·L−1 in MM containing (per liter): 10.5 g K2HPO4, 4.5 g KH2PO4, 2 g mannitol, 2 g glycerol, 5 mg FeSO4, 10 mg of CaCl2, 2 mg MnCl2, 0.2 g MgSO4·7H2O, pH 7.0. Data are the means ± standard errors from three replicates per treatment at 36 h after inoculation. The multiple comparisons of means were obtained using Duncan's multiple-range test with an overall of 0.01. The means differing from each other were indicated with different capital letter (PEffect of nitrogen source on bacterial growth and zeamine production by D. zeae EC1.
