  1. The experimental were tested with final concentration of 1 mM on lipase and biosurfactant stability of O. intermedium strain MZV101 in optimal pH 10, and temperature of 60 °C incubated respectively for 4 h and 24 h. In this study, results are expressed as mean ± S.D. and all tests were examined at least in triplicate independent experiments
