1. A method of increasing algae biomass productivity in an algae culture comprising Cyanidiophyceae, the method comprising:
introducing a feedstock comprising a mixotrophic substrate to an algae culture when the algae culture is exposed to light at an intensity sufficient to support photosynthesis;
not providing supplemental O2 to the algae culture; and
not providing supplemental CO2 to the algae culture,
wherein the algae culture is in a closed culture system.
