Reduction in surface tension values and increase in the yield of biosurfactant during the late log phase of growth indicates that the biosurfactant is a secondary microbial metabolite. The biosurfactant formed stable emulsions with a wide variety of hydrocarbons. The isolated surface-active compound has a potential application in enhanced oil recovery and is stable over a wide range of temperatures (10-120?C) and pH (2-12). This is the first report of effective and stable emulsion formation by a strain ofSerratia marcescens. %N 1 %K Biosurfactant - emulsification - oil recovery - Serratia marcescens - surface-tension %P 133-135 %V 13 %D 1997 %I Springer Science %R doi:10.1007/BF02770821 %L open759
