Cultivation of green alga Botryococcus braunii in raceway, circular ponds under outdoor conditions and its growth, hydrocarbon production

► B. braunii (LB-572 and N-836) strains were used for the current study. ► Cultivated LB-572 and N-836 in both raceway & circular ponds. ► Evaluated biomass yield, hydrocarbon content and fatty acid profile. ► Biomass and hydrocarbon content were observed in various seasons. ► Effect of NaHCO3 on biomass and hydrocarbon production in N-836 were evaluated.
