Muralytic Activities of Ruminococcus albus 8.

Ruminococcus albus 8 was cultured with isolated alfalfa cell walls as the carbon source. The culture broth was assayed for muralytic enzyme activities. The effect, with respect to the production of such muralytic enzymes, of growing the microorganism on different carbon sources was also investigated. Also, the rates of solubilization and utilization by R. albus of individual alfalfa cell wall sugars during a 96-h growth period were examined.
