Abstract
Domestic wastewater from local housing in Palembang was treated in laboratory scale bioreactors adopted a combination of anaerobic baffled reactor (ABR) which consisted of six compartments and constructed wetland (CW), effluent from CW was flown into a settling basin prior to be used further for macroalgae Oedogonium sp biomass cultivation. The wastewater was fed into the bioreactors continuously and achieved a 24 h retention time. Oedogonium sp was cultivated as an open pond, macroalgal biomass achieved logaritmic phases after 20-24 days. Harvested biomass was dried in an oven at 80oC for 12 h, grounded and subjected to a lipid extraction processes by using hexane as solvent for 6 h. Fat content per gram biomass has been extracted was ranged between 5,8 to 6,4 %. GCMS analisis shows the lipid was composed of several fatty acids which potential for biotechnologycal applications such as palmytic acid (13,32 - 16.05 %), hexadodechanoic acid (3,2 - 4,1 %), linolenyc acid (19,19 %), stearic acid (1,29 %), octadekanoic acid (1,82 %), adipic acid (14,97 %) and oleic acid (12,61%).
