Culture conditions: starch-yeast extract medium; pH: 6.5 and incubated at 20°C; carbon source: 2% starch, 0.5% yeast extract; 1% KNO3; 0.1% KH2PO4 and MgSO4·7H2O 0.05%; 230 rpm; cultivation period: 7-day values of means ± SD, n-3. Values in the same column that do not share the same alphabetic superscripts are significantly different at levels according to Duncan’s multiple range test.
