Abstract

BIOSIS COPYRIGHT: BIOL ABS. The oleophilic fertilizer Inipol EAP 22 and a microbial biosurfactant (rhamnolipid) were investigated for their ability to increase the rate of biodegradation of aliphatic and aromatic hydrocarbons by pure bacterial cultures. Both Inipol EAP 22 and rhamnolipid were found to lower the surface tension of a phosphate buffered solution to 32 mN m-1. Each surfactant dramatically increased the apparent aqueous solubility of solid 2-methylnaphthalene, and were capable of emulsifying liquid hydrocarbons. Biodegradation experiments were carried out with the TOL plasmid-containing strain, Pseudomonas putida (ATCC30015); the OCT plasmid-containing strain, P. oleovorans (ATCC29347); and an unknown naphthalene-degrading strain (ATCC15075). Cells were grown under conditions where biodegradative enzymes were induced before their utilization. Model studies were conducted to investigate the ability of Inipol EAP 22 and rhamnolipid to enhance the rate of transport and uptake of hydrocar
