Effect of pH on lipase and biosurfactant stability of O. intermedium strain MZV101.The test were studded in pH 5–13 in temperature 37 °C which incubated 4 h for lipase and 24 h for biosurfactant. Results were represented as mean ± S.D. and all tests are examined at least in triplicate independent experiments. Error bar has indicated standard deviations shown in all figures
