Rhamnolipid as a potent natural biosurfactant has a wide range of potential applications, including enhanced oil recovery, biodegradation, and bioremediation. Observation of tensio-active indicated that biosurfactants were produced by the newly isolated and promising strain Pseudomonas putida. The biosurfactants were identified as rhamnolipids, the amphiphilic surface-active glycolipids usually secreted by Pseudomonas sp. In addition, the ability to generate rhamnolipids by placement of the right microbes might help overcome rhamnolipid adsorption during flow through reservoir rocks and the resultant degradation that would decrease the rhamnolipid concentrations. Their production was observed when the strain was grown on soluble substrates, such as glucose or on poorly soluble substrates. Maximum value 1.13 mg/ ml was occurred on the second day. Production of biosurfactants depends on the nutrient media. The surface tension was decreased with increasing time and growth.
