Growth of Botryococcus braunii (race ‘A’) and production of its constituents viz, hydrocarbon, carbohydrate, fatty acid, and carotenoids were inXuenced by diVerent levels of salinity. Under salinity at 34 mM and 85 mM, 1.7–2.25-fold increase in the relative proportion of palmitic acid and two fold increase in oleic acid were observed. A twofold increase in carotenoid content was noticed at 85 mM
salinity with lutein (75% of total carotenoid) as the major carotenoid followed by -carotene. The increase in biomass yields and
changes in other constituents indicated the inXuence of salinity and the organism’s adaptability to the tested levels of salinity (17 mM to
85 mM).
