Abstract

Biosurfactant production was studied by Bacillus licheniformis K51, B. subtilis 20B, B. subtilis R1 and Bacillus strain HS3 using molasses or cheese whey as a sole source of nutrition at 45 °C. The isolates were able to grow and produce biosurfactant under shaking as well as static conditions. Maximum biosurfactant production was achieved with molasses at 5.0-7.0% (w/v). The biosurfactant retained its surface-active properties after incubation at 80 °C at a wide range of pH values and salt concentrations for nine days. Oil displacement experiments in sand pack columns with crude oil showed 25-33% recovery of residual oil.
