EXTRACTION OF OIL AND BIODIESEL PRODUCTION FROM BIOMASS OF IRAQI STRAIN MICROALGAE –OSCILLATORIA SP.

Biodiesel is made from numerous renewable sources. The current study isolated and cultured a new strain of Oscillatoria sp. on a BG11 medium. The pure culture was identified based on morphological feature. Following the identification of the taxa, the impact of temperature, pH, and light levels on algal fresh and dry weight was investigated. The best development rate was found at 28°C, pH 8, and 1800 lux, according to the findings. The oil extracted using the soxhlet method and the findings of lipid concentration using HPLC revealed that Oscillatoria sp. contains seven different lipids, including (Triolein, Cholesteryl palmitate, Tripalmitin, Phytol, Dipalmitin, Triacylglycerol, and Moonolein. According to the American Society for Testing and Materials, biodiesel was tested using established procedures. For Oscillatoria sp., specific fuel parameters were: kinematic viscosity (3.45 mm2 sec-1), density (0.8897g cm-3), total sulfur content (0.0134%), and flash point (150°C).
