Resumen de: WO2019113116A1

At least one elongated photobioreactor, at a small angle relative to horizontal and mixed substantially or entirely by large bubble flow, is used for contained cell culture, e.g., microalgae cultivation. Elongated, flexible, transparent, polymeric photobioreactor tubes, in near-grade and near-horizontal (e.g. sloped 1 degree to 3 degrees) orientation, and use of low-pressure air mixing, allow very inexpensive construction and operation. Multiple elongated tubes may be used for an independent operation of the multiple photobioreactor tubes for the same or different cells, e.g., microalgae and different applications. Low-pressure air is delivered near the low end of the bioreactor at less than 10 psig and without sparging, to produce large air bubbles that travel from the low end to the high end of the bioreactor, for turbulent mixing and gas exchange. Each inexpensive, flexible bioreactor tube is easily modified to improve internal flow characteristics and suspension of cells, and/or to include sensor and/or sampling collars and ports.

Methods of culturing microorganisms in non-axenic mixotrophic conditions are disclosed. A method of culturing microalgae mixotrophically and controlling bacterial contamination with an acetic acid/pH auxostat system is specifically described. The pH auxostat system is activated with an initial concentration of sodium acetate to start supplying acetic acid at a concentration of 15-50% (v/v) to the culture wherein the pH auxostat system operates within 6-9 and the temperature ranges from 10 ºC-30 ºC. Methods of culturing microalgae mixotrophically with an increased productivity through an increase in oxygen transfer to the culture, and controlling bacterial contamination with an oxidative agent are also described.
