Application of biosurfactant produced by an adaptive strain of C.tropicalis MTCC230 in microbial enhanced oil recovery (MEOR) and removal of motor oil from contaminated sand and water
Review articleOpen access
Abstract:

Highlights•Biosurfactant produced from an adaptive strain C. tropicalis MTCC230 was functionally characterized as surfactin.•It can significantly reduce the surface tension of water from 72 mN/m to 32 mN/m, with the critical micelle concentration (CMC) of 32.5 mg/l.•It was stable over wide range of pH(2–12), temperature (30ºC-90 °C) and salinity(2%–10%).•In sand-pack column experiment ∼39.80% additional oil was recovered (AOR) this shows its direct approach for MEOR in oil reservoirs.
