Abstract

Summary: Growth of the acetogenic anaerobe on methanol/CO mixtures is limited by the rate at which CO can be assimilated. This limitation can be offset by the consumption of acetate as an additional co-substrate. Growth on methanol/CO/acetate mixtures improves growth rates but stimulates production of an unidentified polymer leading to cell aggregation and wall growth under chemostat conditions. Production of butyrate as major fermentation end-product leads to growth inhibition visualized by an increased maintenance requirement as demonstrated by estimations.
