Chemical characteristics of different concentrations of sugarcane industry wastes for algal culture
ANMAI Khan, MAB Habib, MS Hossain
Sugarcane industry wastes media made of press mud, sugar mill effluent and by-products before inoculation of Chlorella vulgaris, the chemical properties were analyzed such as dissolved oxygen (DO), hardness, chemical oxygen demand (COD), total solids (TS), total suspended solids (TSS), total dissolved solids (TDS). Different categories including some inorganic media 18 (eighteen) treatments were tested such as inorganic media enriched with sodium acetate, sugarmill effluent medium (SMEM), press mud medium (PMM), normal molasses medium (NMM) and red sugar medium (RSM) with a control Bold basal medium (BBM). Hardness and COD were determined maximum 85.5 mg/l & 2724.21 mg/l in PMM1.5 g/l and RSM1.2 g/l respectively and the minimum hardness 22.8 were found in RSM0.4 g/l, RSM0.8 g/l,RSM12 g/l. Similarly the COD was found minimum 826.96 in 25% SMEM. Proximate composition shows that maximum protein 10.35% were determined in press mud followed by 4.17% in molasses and 0.27% in red sugar. Similarly significantly (P<0.05) higher lipid was determined in press mud than those in molasses and red sugar.
