Fig. 7From: Bioflocculants’ production in a biomass-degrading bacterium using untreated corn stover as carbon source and use of bioflocculants for microalgae harvest A Effects of different volume ratios of GO2 fermentation broth/algal culture on the flocculating efficiencies of two green microalgae, Chlorella zofingiensis and Neochloris oleoabundans. Microscopic views of Neochloris oleoabundans cells before (B) and after (C) bioflocculation. Data are the means of four replicates ± SE, and bars with different letters are significantly different at p < 0.05 according to Duncan’s multiple range test. Bar = 50 μmBack to article page
