Cultures of microorganisms have been isolated that convert CO, H/sub 2/ and CO/sub 2/ in coal synthesis gas into methane or ethanol. The reactions are severely mass transfer limited and bioreactor design will be a critical factor in the application of this technology. This paper presents results of culture isolation studies and development of continuous reactors for these cultures. The results of bubble columns and stirred tank reactors are presented and discussed. Methods for defining mass transfer coefficients and intrinsic kinetics are presented. Operation of these gaseous fermentations at high pressure has enabled complete conversion in reaction times of a few minutes.
