Abstract
Disclosed herein are methods and systems for membrane carbonation for cultivating microalgae and other microorganisms that utilize a gaseous substrate, as well as to upgrade the quality of mixed-gas streams.
Claims14
A method of cultivating a photoautotrophic organism in a photoautotrophic culture, the method comprising:
- providing a membrane carbonation system comprising a plurality of non-porous hollow-fiber membranes, wherein each of the non-porous hollow-fiber membranes comprises a lumen;
- at least partially submerging the plurality of non-porous hollow-fiber membranes into the photoautotrophic culture;
- delivering a mixture of gases comprising CO2 to the lumen of each of the non-porous hollow-fiber membranes;
- diffusing the CO2 through the non-porous hollow-fiber membranes into the photoautotrophic culture;
- gathering pH data regarding a pH of the photoautotrophic culture;
- and
- controlling delivery of the mixture of gases comprising CO2 based on the pH data.
