With increasing demand of biosurfactants for environmental and industrial application, there is increased interest in prospecting of microorganisms and substrates for production of substantial quantities of biosurfactants. A study was carried out to investigate the ability of Bacillus sphaericus EN3 and Bacillus azotoformans EN16 to produce large quantities of biosurfactants and determine a suitable substrate for its production. The organisms were previously screened for biosurfactant… Expand
