EVALUATION OF BIOACTIVE COMPOSITION FOR SPIRULINA PLATENSIS BM GROWN UNDER AQUEOUS CONDITION USING EFFLUENT FROM ANAEROBICALLY TREATED PIG WASTEWATER

Abstract

The study evaluated chlorophyll, carotene and cacbonhydrate content from Spirulina platensis BM grown under aqueous conditions using effluent from anaerobically treated pig wastewater at different wastewater concentrations. The results showed that anaerobically treated pig wastewater was a suitable source of N for the growth and development of Spirulina platensis BM. N composition of wastewater: 1.51mg/l N_NO₃^- 157mg/l N_NH₄⁺; 192mg/l total Nitơ. The results of evaluation of carotene, chlorophyll and cacbonhydrate content in algae showed that at 60% wastewater rate, the highest carotene, chlorophyll and cacbohydrate content was 3.98mg/g; 8.34mg/g and 35.43 % respectively.
