Abstract

The effects of the presence of commercial non-ionic surfactants on the cell growth and diesel degradation by Pseudomonas sp. OSD were studied. Most surfactants inhibited the diesel biodegradation at high concentration(1000mg/1). However, some surfactants showed no inhibition at lower concentrations. Tween 20, Brij 58, Brij 78 were not inhibitory to the diesel biodegradation even at high concentration. These chosen surfactants has relatively high HLB values. There exists complicated relationship for diesel bioremediation between cell hydrophobicity, surfactant HLB, contaminants, an soil.
