    摘要: 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.

    摘要: 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.

    摘要: Disclosed herein are aquafeed, animal feed and fertilizer compositions comprising microalgae clinched with minerals and a method of enriching microalgae with minerals in non-metabolized form. Specifically, the method includes the creation of an enriched microalgae product through the assimilation, reversible chelation, and absorption of supplemental minerals required in the diet of adult fish and other aquatic animals which minimizes leaching of the supplemental minerals before ingestion by the fish. Additionally, the enriched microalgae product can be used as both a direct feed or fertilizer, or as part of an aquafeed, non-aquatic animal feed, or plant fertilizer mixture. The combination and proportion of the minerals can be adjusted to the animal or plant receiving the mineral enriched algae composition.

    摘要: 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.
