Microalgae based biofertilizers: A biorefinery approach to phycoremediate wastewater and harvest biodiesel and manure

摘要: Abstract The most important requirement of the agrarian advancement is resilient nutrient source for agriculture without jeopardizing environmental assets and economy country. An algal biorefinery approach prime sustainable production biodiesel biofertilizers after remediation wastewater. In present study, microalgae Chlorella minutissima, Scendesmus spp Nostoc muscorum their consortium were used approach. C. minutissima has shown maximum phycoremediation potential when compared to other possible microalga consortium. Experimental results showed that removal NH4+-N, NO3−-N, PO4−3-P, TDS, BOD5 COD found be 92, 87, 85, 96, 90 81% respectively. dry biomass was observed in followed by spp, N. muscorum, i.e., 0.45 ± 0.01 g L−1, 0.44 ± 0.02 g L−1, 0.14 ± 0.03 g L−1 fraction nitrogen phosphorus C. minutissima, 5.46 ± 0.27 0.85 ± 0.03 lipid productivity recorded (81.23 ± 4.5 mg L−1) N. muscorum (14.29 ± 8.7 mg L−1) (11.33 ± 5.6 mg L−1). Using this as manure one can save chemical fertilizer worth about 5584 $ (US Dollar) ha−1 yr−1. study not only supports phytoremediation, production, organic utilization directly but indirectly combat climate change scenario through minimizing greenhouse gases production.
