Abstract

Studies on the biosurjactants produced by Pseudomonas aeruginosa CF TR- 6 revealed that they consisted of glycolipids R-1 and R-2. A time course study of fermentation indicated that the appearance of glycolipids in the jiv-mentation broth coincided with the exhaustion of nitrogen arid the commencement of the stationary phuse with respect to biomass. The efect of variation of the media components such us carbon, nitrogen, phosphute and metal ions has been investigated. The jbllowing values were .found to be optimum ,fbr biosurjactant production: glucose, 20 g dm - 3; carbon to nitrogen rutio, 38; phosphate, 30 mmol dm- 3; MgSO,. 7H20,10 0 mg dm- ’. Adtlitiori of’ iron to the medium signijicantly diminished the glycolipid yield.
