A method for stimulating enhanced lipid accumulation by algae includes growing algae in a bioreactor medium including nutrients. The algae have an average lipid content that averages a first % of total cell biomass. A stress inducing environmental condition is initiated that keeps the algae alive, stops cell reproduction, and induces the algae to accumulate additional lipids resulting in a second average lipid content that is at least 50% more than the first %. The method can include measuring a lipid concentration of the algae while under the stress inducing environmental condition, harvesting lipids from more than 50% but not all of the algae when the lipid concentration is above a predetermined lipid limit, adding fresh medium to the bioreactor medium having algae not involved in the harvesting therein, and repeating the method, wherein the algae not involved in harvesting serves as a source for new algae growth. |
