Effect of pH on activity of the purified protease. Results are presented as mean ± SD ( 𝑛 = 3 ). Different letters (e.g., a, b, c, and d) next to the data points indicate statistically significant difference ( 𝑃 < 0 . 0 5 ) when the data are analyzed by analysis of variance followed by Duncan’s multiple range test.
