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.
Abstract:
Methods and apparatus for culturing microorganisms are described, including culturing in mixotrophic culture conditions. A bioreactor array with multiple culture vessels with independently controllable inputs is used to culture similar cultures of microorganisms in which at least one parameter differs from other culture vessels in the bioreactor array.
Abstract:
Disclosed here are compositions rich in omega-7 fatty acids, including palmitoleic acid, and products rich in omega-7 fatty acids derived from algal biomass. The algae and/or compositions rich in omega-7 fatty acids may be used in products or as ingredients of products. Methods and systems for increasing the production or concentration of omega-7 fatty acids, and isolating omega-7 fatty acids from algal biomass are also disclosed herein.
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:
Methods of treating contamination, particularly bacterial contamination, in an open culture of microalgae with organic carbon are described herein. The methods comprise reducing the pH of a culture for a period of time and then raising the pH of the culture, wherein the culture comprises the presence of a first acid and the culture is contacted with a second acid to reduce the culture pH from a first pH value to a second pH value. The culture is maintained at the second pH value for at least 5 minutes before the culture pH is raised from the second pH value by contact with a base.
