title: Hydrogen utilization by clostridia in sewage sludge.
abstract: A sporeformer morphologically different but physiologically similar to Clostridium aceticum Wieringa was isolated from sewage sludge. It used large amounts of H2 and CO2, converting them chiefly to acetic acid. Growth occurs anaerobically on yeast extract alone, but after the nutrients in yeast extract are used, growth continues at a reduced rate, supported by the conversion of the gases to acetate.
