Abstract: Systems for culturing mixotrophic microorganisms on a large scale in thermally stable open systems are disclosed. Embodiments of the system include features such as lit portions, dark portions, organic carbon delivery systems, gas delivery systems, submersible thrusters for mixing, and turning vanes for guiding fluid flow. Multi-functional embodiments of the turning vane provide guidance for fluid flow and other functions such as heat exchange, nutrient delivery, gas delivery, organic carbon delivery, delivery of light, and parameter measurement by sensors.

Abstract: Bioreactor systems for culturing mixotrophic microorganisms in open cultures on a large scale are disclosed herein. Embodiments of the system comprise organic carbon delivery systems and submersible thrusters suspended on adjustable support structures.

Abstract: Methods of culturing mixotrophic microorganisms in a state of balanced gas composition are disclosed. Parameters of a culture of mixotrophic microorganisms may be controlled to reduce the requirements of externally supplied gases and optimize the production and consumption of gases within the culture by the phototrophic and heterotrophic metabolisms of the mixotrophic microorganisms.
