Abstract

It was previously reported that rhamnolipid bisurfactant from Pseudomonas aeruginosa ATCC 9027 can be used to remediate contaminated sites. Since the effective use of rhamnolipid require an understanding of its morphology as well as the effects of pH and organic and inorganic contaminants on that morphology, cryo-transmission electron microscopy was used to examine the morphology of vitrified, frozen hydrated suspensions of rhamnolipid over a pH range of 5.5 to 8.0. The effect of a model alkane, octadecane and a model heavy metal cadmium on the morphology of the rhamnolipid was also determined. Results obtained are found to be satisfactory.
