Abstract

The invention provides systems and methods for the delivery of carbon to photoautotrophs. The invention utilizes low energy regeneration of adsorbent for CO2 capture and provides for effective CO2 loading into liquids useful for photoautotroph growth and/or production of photosynthetic products, such as biofuels, via photoautotrophic culture media. The inventive system comprises a fluid/membrane/fluid contactor that provides selective transfer of molecular CO2 via a dense (non-porous) membrane from a carbonate-based CO2 snipping solution to a culture medium where the CO2 is consumed by a photoautotroph for the production of biofuels, biofuel precursors or other commercial products.
