Crystalline lysozyme prepns. in concns. greater than 1.6 [mu]g. per ml. inhibited almost completely O2-uptake by M. lysodeikticus in dilute suspensions. Smaller concns. of lysozyme (0.52 [mu]g./ml.) caused an increase in the rate of respiration of Na acetate and ethyl alcohol. Several mechanisms which may cause this stimulation are discussed. It is suggested that lysozyme may hydrolyze its specific substrate, a mucopolysaccharide, from the cell membranes thus rendering them more permeable to the substrate molecules. Exptl. evidence indicates that such may occur.
