Abstract
The effect of pH on plant protease activity was investigated using buffered, gamma‐irradiated aqueous extract of ryegrass Lolium multiflorum. Rapid protein breakdown occurred in the first few days but was followed by a longer period of reduced activity. The overall pH optimum for ryegrass proteases was between 5·0 and 7·0 but there was still considerable activity at the acid pH levels found, eg in silage. Proteolysis did not proceed to completion even when the pH was not inhibiting.
