Biological decomposition techniques and isolation of environmental pollutions using biosurfactant bacteria
are one of the effective methods of environmental protection. Biosurfactants are amphilice compounds were
produced from several species of bacteria. They are environmentally friendly, biodegradable, less toxic and
This paper is designed to investigate experimentally removal of oil from oily sludge by biosurfactants. For
this purpose, Preparation of biosurfactant was done in glass flasks and laboratory conditions. The surface
tension of culture was measured by tensiometer. Finally, a study for the feasibility of removing oil from
sludge by biosurfactant sixteen of experiments were designed.
