The experiments were conducted in an Algal Microbial Fuel Cell (AMFC) photobioreactor (single-chamber). The pH, electrical conductivity (EC), chemical oxygen demand (COD) and total dissolved solids (TDS) decreased from 8.01 to 7.0, from 982 to 854 (mS/cm), from 255 to 112 (mg/L) and from 490-427 (mg/L), respectively, over course of 7days. Biomass production, biomass production rate, chlorophyll a, b and "total chlorophyll" increased with increasing time and were observed to be 3300 mg/L, 471.42 mg/L/day, 0.981 mg/L, 0.173 mg/L and 1.156 mg/L after 7 days. Lipid production and lipid production rate were 1068.383 mg/g dry wt. biomass and 152.62 mg/g dry biomass/day. FTIR spectra revealed the presence of protein, lipid, FAs, triglycerides and ester functional groups. Fatty acid methyl esters (FAME) profile revealed the presence of C16:0, C18:2n-6, C18:1 and C16:1. The generation of electric potential by Leptolyngbya sp. JPMTW1 increased significantly (p ≤ 0.05) from 0.0211 to 0.264 mV within 7 days. The maximum power density (0.008 mW/cm2) was obtained at cell potential at 12mV. This study shows that simultaneous production of biofuel, bioelectricity and wastewater treatment is possible by Leptolyngbya sp. JPMTW1.
