| description | <abstract language="eng">1 - Anaerobic bacteria of the Clostridium genus acidify mineral media without when agar is added. 2 - Acidulation results from the attack on the agar as a source of carbon. 3 - The quantity of CO² produced by the decomposition of the agar is approximately that obtained with soil bacteria as shown by Waksmann and Diehm working with hemicelluloses. Although galactone is less atacked than the other hemicelluloses the acidity produced is sufficient to disturb the fermentation tests in semi-solid media with agar. 4 - The acidulation of Spray's sugar-free control medium is probably due to the decomposition of the agar by anaerobes. The acidity produced may interfere with the acidity of the fermentation of the sugar in Spray's test or may be added to it, thus giving a false indication of the real acidity. |
