dc.description.abstractThe optimum conditions for biosurfactant production by Iran's isolates were examined. The Taguchi method was used to identify nutritional requirements in the medium using four parameters; that is, carbon source, nitrogen, phosphorous, and salt concentrations. The use of whey, oil, and sucrose as carbon sources; NaCl as salt source; (Na2HPO4, NaH2PO 4) as phosphorous source; and (NH4)2SO 4 as nitrogen source was examined to determine bacteria optimum conditions. According to the Taguchi method using the sucrose source, the optimal conditions for Bacillus subtilis were 50 g/L NaCl, 13.53 g/L (Na 2HPO4, NaH2PO4), and 1 g/L (NH 4)2SO4; for Bacillus cereus they were 25 g/L NaCl, 13.53 g/L (Na2HPO4, NaH2PO4), and 1 g/L (NH4)2SO4; and for Pseudomonas putida they were 25 g/L NaCl, 13.53 g/L (Na2HPO4, NaH 2PO4), and 1 g/L (NH4)2SO 4. Oil displacement experiments in the micromodel at optimum conditions showed around 25% recovery of residual oil with added supernatant of Bacillus subtilis. Copyright © Taylor & Francis Group, LLC.-
