Abstract From sludge obtained from the sewage digester plant in Marburg-Cappel a strictly anaerobic bacterium was enriched and isolated with carbon monoxide as the sole energy source. Based on morphological and physiological characteristics the isolate was identified as a strain of Peptostreptococcus productus, which was called strain Marburg. The organism was able to grow on CO (50% at 200 kPa) as the sole energy source at a doubling time of 3 h and converted this substrate to acetate and CO2. The type strain of P. productus was not able to grow at the expense of CO. Electron microscopic investigations of strain Marburg cells revealed a cell wall which was different from that of other Gram-positive prokaryotes. DNA:DNA hybridization studies of the DNA isolated from strain Marburg and the type strain as well as some morphological and physiological properties of both strains confirmed the low degree or relatedness between the two strains.
