Production of MBF-L804 using different lignocellulosic biomasses as carbon source. Strain L804 was cultured in the mediums (added with 3 g/L yeast extract as nitrogen source and with different biomasses as carbon sources) and the control medium (added with 3 g/L yeast extract, but without added biomasses). 100 μL of fermentation broth of 48 h was taken for flocculating activity assay
