Pseudomonas maltophilia CSV89, a soil bacterium, produces an extracellular biosurfactant, “Biosur-Pm”. The partially purified product is nondialyzable and chemically composed of 50% protein and 12–15% sugar, which indicates the complex nature of Biosur-Pm. It reduces the surface tension of water from 73 to 53×10-3 N m-1 and has a critical micellar concentration of 80 mg/l. Compared to aliphatic hydrocarbons, Biosur-Pm shows good activity against aromatic hydrocarbons. The emulsion formed is… CONTINUE READING
