Fig. 3From: Valorization of untreated rice bran towards bioflocculant using a lignocellulose-degrading strain and its use in microalgal biomass harvestEffects of Na2CO3 concentrations on the flocculating activity and yield of RBBF-C9. The 24-h fermentation broth was collected for analysis. The medium contained 20 g/L of untreated rice bran and 3 g/L of yeast extract.
