Enhancing microalgal lipid production is the recent attraction because of its application in bio-fuel production, there are various methods developed on targeting the improvement of lipid yield in microalgae. In this study two different nutrient feeding methods was used to modulate the algal nutrients. Supplying all of the nutrients required for the entire growth phase in one initial feeding; feeding the optimal quantity of nutrients at a regular interval as it was consumed by the algae. The results revealed; method -B found suitable for biomass production, whereas method -A found ideal for activating the lipid accumulating system with less biomass yield.
