This　study　aimed　to　compare　the　biomass　and　oil　productivity　from　three　selected　microalgae　strains　(Botryocococcus　braunii,　Scenedesmus　dimorphus,　and　Nannochlorpsis　sp)　using　livestock　wastewater　for　dual　purposes　of　biofuel　production　and　animal　waste　nutrient　removal.　The　selected　algal　strains　were　batch-wise　cultivated　in　the　laboratory　in　Basal　medium　and　livestock　wastewater　with　optimal　nutrient　concentration.　The　results　indicated　that　all　three　algae　strains　grew　better　in　50%　autoclaved　wastewater　than　in　Basal　medium.　The　maximum　lipid　yield　of　B.　braunii,　S.　dimorphus,　and　N.　sp　were　0.61　g/l　(38.88%　lipid　content),　0.69　g/l　(61.76%　lipid　content),　and　1.32　g/l　(37.47%　lipid　content)　all　in　50%　autoclaved　wastewater.　N　and　P　in　wastewater　were　completely　removed　by　the　three　selected　strains　at　day　21,　respectively.
