Initial rates of hydrolysis of lysozyme against several lyophilized bacteria. Substrate suspensions (10⁷ cells/ml) were incubated with 2.5 mg/ml of lysozyme. One enzyme unit was defined as the amount causing decrease of 0.1 absorbance units at 540 nm in the reaction for 1 min at 25°C. The essay was performed in triplicate per sample.
