Comparative secretome analysis of the A. niger O1 in shake-flask fermentation. a SDS-PAGE analysis of secreted proteins in 2 days, 4 days, 6 days supernatants of O1 fermentation cultures. b Category of identified proteins in 2 days, 4 days, 6 days supernatants of O1 fermentation cultures. GH glycoside hydrolase; PL polysaccharide lyase. c Venn diagram of the comparison of identified proteins in 2 days, 4 days, 6 days supernatants of O1 fermentation cultures. d A schematic diagram that roughly displayed the detailed varieties and relative amount of secreted protein by A. niger O1 after 2 days, 4 days, 6 days cultivation
