Palm Oil Mill Effluent (POME) as a microalgae local mixed culture medium is useful for recycling waste water as well as a source of nutrients by utilizing inorganic materials to synthesize lipids, carbohydrates, and proteins for microalgae local mixed culture. POME has fundamental nutrients and organic materials COD and BOD. This research was conducted for 7 days of cultivation of local mixed culture grown in Bold's Basal Medium (BBM) as a control medium and medium contained POME with concentrations of 2.5%, 5%, 7.5%, 10%, 12.5%, and 15% as treatments. The parameters observed included cell count, dry weight, carbohydrates, proteins and microalgae lipids content and reduction of BOD and COD. The results showed that POME increased the growth of local mixed culture by 1.80 x 106 cells/ml and biomass by 0.33 mg/ml at 10% concentration respectively. Optimum lipid content was 99.27 mg/ml at 10% concentration, optimum carbohydrate was 30.32 mg/ml at 12.5% concentration, and optimum protein was 2906 μg/ml at 10% concentration. BOD and COD on POME medium decreased after cultivation with local mixed culture. |
