Biosurfactants are unique secondary metabolites, synthesised non-ribosomally by certain bacteria, fungi and yeast, with their most promising applications as antimicrobial agents and surfactants in the medical and food industries naturally produced glycolipids and lipopeptides are found as a mixture of. The selection of pseudomonas aeruginosa for the separation of biosurfactant was determined the crude biosurfactant was extracted from the supernatant and the yield of the crude biosurfactant was about 1 g/l some surface properties of rhamnolipids biosurfactant were evaluated it also showed antimicrobial activity. Furthermore, the antimicrobial activity of the resulting silver colloids has been analyzed against escherichia coli, pseudomonas aeruginosa and staphylococcus aureus the biosurfactant stabilized nps slightly increased the inhibition of e coli in comparison with citrate stabilized ag nps the use of this.

One of potential areas in which the usefulness of biosurfactants has been studied is its antimicrobial activity, which is catching good attention worldwide the biosurfactants acts as an effective antimicrobial agent against a number of pathogenic organisms in the present research work, a systematic isolation.
