TLDR
The present research work was undertaken with a mandate to study carbon spectrum utilization and structural characterization of biosurfactant produced by indigenous Pseudomonas aeruginosa NCIM 5514, which showed unique properties to utilize a large number of carbon sources effectively for production of biosURfactant, although glucose was the best carbon substrate.About:

Microbial production of surfactants and their commercial potential.
JD Desai,Ibrahim M. Banat +1 more
TL;DR: Biosurfactants are more effective, selective, environmentally friendly, and stable than many synthetic surfactants, and the most promising applications are cleaning of oil-contaminated tankers, oil spill management, transportation of heavy crude oil, enhanced oil recovery, recovery of crude oil from sludge, and bioremediation of sites contaminated with hydrocarbons, heavy metals, and other pollutants.

Surface-Active Agents from Two Bacillus Species
TL;DR: It is suggested that earlier reports of biopolymers which both stabilized emulsions and lowered surface tension were actually similar aggregates of lipid and bioemulsifier.

TL;DR: Investigation of possible methods to enhance the rate of biodegradation of oil sludge from crude oil tank bottom, thus reducing the time usually required for bioremediation found that the level of amendments, incubation time and combination of amendments significantly influenced bacterial growth, protein concentration and surface tension at a 1% probability level.
