Abstract/ Executive Summary:

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 PMM_1.5 _g/l and RSM_1.2 _g/l respectively and the minimum hardness 22.8 were found in RSM_0.4 g/l, RSM_0.8 _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.

Program Area: Postharvest and Agro-processing

Commodity: Sugarcane

Objectives:

To determine some important physico-chemical characteristics of the media and chemical composition of these raw ingredients used for the media preparation.

Methodology:

Before inoculation of Chlorella vulgaris in different culture media made of sugarcane industry wastes in different concentrations sub samples were collected and chemical properties such as dissolved oxygen (DO), hardness, chemical oxygen demand (COD), total solids (TS), total suspended solids (TSS), total dissolved solids (TDS), were analyzed following standard methods [4]. Including some inorganic media 18 (eighteen) treatment were tested in different categories such as inorganic media enriched with sodium acetate, sugarmill effluent media (SMEM), press mud media (PMM), normal molasses media (NMM) and red sugar media (RSM) with a control medium Bold basal medium (BBM). Fresh press mud media (PMM) was first decomposed in three different concentrations (0.5 g/l, 1.0 g/l and 1.50 g/l) in room temperature. Then supernatant were taken and diluted with de- ionized water in different ratio to make different concentrations of the media. Proximate composition of raw ingredients such as press mud, molasses and red sugar were determined according to Horwitz method [10]. Means of the determinants were compared through statistical analysis one way ANOVA using Tukey Test.

Achievement/Findings:

At present algal culture for commercial live food development not yet developed in Bangladesh and the standard inorganic media like Bold basal medium (BBM) is expensive. So that it is not economic to produce microalgae using BBM for live food culture in aquaculture practice or other means. Sugar mill effluents, press mud and sugar mill by-product such as molasses are inexpensive and easily available ingredients in Bangladesh. These agroindustrial wastes and byproduct may be used as organic media for algal culture to fore commercial live food development and simultaneously the country will be free from aquatic pollution partially.
