Abstract

Biosurfactants produced by Pseudomonas aeroginosa KK-7 were purified and their properties were studied. The bacterial surfactant was seperated into two sorts of biosufactants (Type I, 11) by silica gel column chromatograpgy. On the basis of physiochemical analysis, Type I was found to be mixture of two glycolipids with M.W. 800, and Type II was peptide with M.W. 1300. The Type 11 biosurfactant was compose of glutamic acid, proline, glycine, leucine, histidine. The crude extract was used to dertermine some properties as a surfactant. The biosurfactant had the properties as stronger emulsification agent and a stronger stabilizing agent emulsion than any other surfactants tested.
