Alkane production from CO2 and H2. Acetobacterium woodii was grown with CO2 and H2, and cell growth and acetate production were measured (a). After 6 days, the acetate-containing A. woodii medium was used as the feed for alkane-producing A. baylyi in fed-batch culture (b). The feed rate was manually controlled to keep the acetate concentration in the medium between 30 and 70 mM. A. baylyi utilized the feed for growth and alkane production (b). Due to the relatively dilute feed (containing approximately 190 mM acetate), the culture volume of the A. baylyi cultivation increased from 300 to 800 mL during the process
