The study was aimed to evaluate the potential of some native algal species taking into account their growth rate and the lipid yield as measure of productivity. Following the sampling from some native habitats two algal species were chosen based on the presence of oil and identified as: Pithophora sp. (Chlorophyte) and Botrydiopsis arhiza Borzi (Xanthophyte). Subsequently maximum specific growth rate was estimated after optimization of some growth factors which came out to be 0.49±0.022 doubling/day of Pithophora sp. at light intensity; 25 :mole/m^2/s, temperature; 25±1°C, pH; 8 while 1.97±0.036 doubling/day of Botrydiopsis arhiza at light intensity; 200 :mole/m^2/s, temperature; 30±1°C, pH; 6. The total lipid content derived using Folch's method was found to be 27.99% ±1.09 in Pithophora sp. while 47.99 % ±0.722 in Botrydiopsis arhiza on the basis of dry mass.
