  3. Abstract:
  4. Effect of several auxiliary carbon sources such as crude oil, different precultures, and quality of adding crude oil in treatment of petroleum wax deposits by an isolated bacterial strain, BBRC9012, was investigated. First and second experiments which compered effect of molasses, glucose and crude oil, indicated that glucose and molasses causes more microbial growth, biosurfactant production and bioemolsification than crude oil. Both optometry and Surface tension measurements showed that using molasses-BHB preculture for wax treatment is not suitable and when crude oil is used as auxiliary carbon source a one day lag phase is unavoidable. It was also shown that when crude oil is added to aqueous phase, microbial growth and biosurfactant production are more but emulsification is less according to observations. Direct addition of crude oil to wax deposits causes to separate all of the wax deposits together
