Cultivation of Microalgae Spirulina platensis Biomass Using Palm Oil Mill Effluent for Phycocyanin Productivity and Future Biomass Refinery Attributes

Palm oil mill effluent is a type of wastewater which contains high concentration organic nitrogen, phosphorus, and different supplement substances. These substances support enhance the growth microalgae. Cyanobacteria Spirulina platensis blue-green microalga with two phycobiliproteins as its primary constituents. Phycocyanin natural blue colourant used in biomedicines, cosmetics, diagnostics, treatments, environmental protection. Chlorophyll pigment plays significant role photosynthesis where photosynthetic process uses atmospheric carbon to produce starch lipid can eventually be converted into desirable products such biodiesel. Therefore, this study, was cultivated concentrations diluted POME (10-50%, v / ) at id="M2"> 26 ± 1 °C room temperature, 90 μmol photon m-2 s-1, aerated for 24 h continuously. The monitored through optical density 680 nm 15 days. highest biomass yield obtained control medium 30% were id="M3"> 1.27 0.02 id="M4"> 1.16 0.01 g/L, respectively. phycocyanin from harvested nutrient media id="M5"> 175.12 22.32 mg followed by id="M6"> 163.55 20.15 purified id="M7"> 87.11 5.20 id="M8"> 85.31 4.33 mg, peak properties amide group 1655.17 cm-1 (C=O stretching), FT-IR analysis revealed well-formed all characteristic peaks distinct fingerprints phycocyanin. ultrasound method produces ( id="M9"> 28.6 0.7 %) consists stearic (38.45%), palmitoleic id="M10"> 25.72 ), palmitic id="M11"> 17.71 0.04 fatty acid methyl esters. FAME produced extracted has potential biodiesel applications. Since essential nutrients optimum environment productivity, it production.
