The effect of Tween 80, a nonionic surfactant, on the extent of biodegradation of phenanthrene by Sphingomonas sp. 2MPII and n-eicosane by Corynebacterium sp. 8 was investigated. This surfactant was beneficial only for phenanthrene biodegradation, where it increased the extent of degradation from 54 to 74%. It appears to be used as carbon source by Corynebacterium sp. 8 but the extent of biodegradation decreases from 43 to 20%. In sand-containing cultures, the phenanthrene sorption observed only in the presence of Tween reduced the biodegradation extent to 35%. On the other hand, for n-eicosane, which remains in the aqueous phase, the biodegradation extent was markedly enhanced to 74%. [ABSTRACT FROM AUTHOR]
