A novel biosurfactant producing Kocuria rosea ABR6 as potential strain in oil sludge recovery and lubrication
Abstract Biosurfactants are amphiphilic molecules composed of a hydrophilic and hydrophobic moiety and had the ability to penetrate into different phases to reduce the surface tension. This features caused to oil recovery, lubrication and facilities of crude oil in pipeline. In current research Bios...
