"The Membrane-Biofilm Photobioreactor (MBPR) for Biofuel Production from Waste CO2"



Algae grow more quickly when supplied with gaseous CO2, yet an efficient and cost-effective means to supply CO2 to algae is lacking. We propose using gas-permeable hollow-fiber membranes to deliver waste CO2 to algal biofilms forming on the membrane surface. We call this the membrane-biofilm photobioreactor (MBPR), and it is ideal to convert waste CO2 to biofuels and other valuable products. In this presentation, I will describe membrane-based biofilms and our most recent research on the MBPR.
