Description An integrated approach has been proposed to produce microalgal biodiesel using both raw wastewater (RW) and
anaerobically digested wastewater (ADW) of food processing industry without addition of extra nutrients or
carbon source for cultivation besides obtaining effluent discharge permissible limits of TN, TP, and COD. Three
microalgae species cultivated with following different combinations: RW, ADW, RW+ADW, and
glucose+ADW. Results indicated that the addition of RW as a carbon source in ADW significantly enhanced BP,
LP, and TN removal as compared to the ADW alone. The runs with RW+ADW removed COD, TN, and TP by
89%, 84%, and 70%, respectively. Sc. obliquus showed highest biomass and lipid productivities (211 and
27.5 mg Lāˆ’1 dāˆ’1) for RW+ADW. The addition of RW or glucose in ADW significantly lowered PUFA contents to
5ā€“15% CDW (as against 35ā€“50% with ADW) for Chl. sorokiniana and Sc. obliquus.
