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. date: 1997 date_type: published publication: World Journal of Microbiology & Biotechnology volume: 13 number: 1 publisher: Springer Science pagerange: 133-135 id_number: doi:10.1007/BF02770821 refereed: TRUE issn: 0959-3993 official_url: http://dx.doi.org/10.1007/BF02770821 related_url_url: http://www.springerlink.com/content/g1569615310vm247/ related_url_type: pub citation: Pruthi, V. and Cameotra, Swaranjit Singh (1997) Production of a biosurfactant exhibiting excellent emulsification and surface active properties bySerratia marcescens.
