英文摘要	In this study, a rapid and efficient method for screening biopolymer producers was established using 96-well plates. An indigenous biopolymer producer Pseudomonas stutzeri XP1 was isolated from Xinjiang oil reservoirs, China. Strain XP1 can grow and produce 16 g/l biopolymer using corn starch and nitrate. Produced biopolymer increased culture viscosity up to 2384 mPa s. Biopolymer showed rheological properties and pseudo-plastic behavior. The viscosity of 8 g/l biopolymer solution kept higher than 25 mPa s at 20-50 degrees C and pH values (5-9) and increased to 7600 mPa s with NaCl concentrations increasing to 2%. Gel permeation chromatography data showed that the biopolymer average molecular mass was 1.65 x 10(6) Da. Gas chromatography revealed that the monosaccharide composition in biopolymer was glucose. Core flooding experiments revealed that extra 13.56% of oil was recovered by in situ biopolymer production of strain XP1. Properties of strain XP1 and the biopolymer produced make them promising for enhanced oil recovery.
