Title: Water/carbonate stripping for CO.sub.2 capture adsorber regeneration and CO.sub.2 delivery to photoautotrophs

The invention provides systems and methods for the delivery of carbon to photoautotrophs. The invention utilizes low energy regeneration of adsorbent for CO.sub.2 capture and provides for effective CO.sub.2 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 CO.sub.2 via a dense (non-porous) membrane from a carbonate-based CO.sub.2 snipping solution to a culture medium where the CO.sub.2 is consumed by a photoautotroph for the production of biofuels, biofuel precursors or other commercial products.
