additional information in microemulsion medium (water/2-ethylhexylsulfosuccinate/decane) turnover-number values exhibit a deformed W-shaped profile with omega (the water/surfactant mol ratio). At pH 7, a maximum value of turnover-number is observed at omega = 10.6. The turnover numbers are higher in microemulsion medium than in aqueous medium at both pH‘s 7 and 8 Aspergillus niger
