The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

A series of alkylcyclohexyltetralins (ATEs) and an alkylcyclohexylnaphthalene were exposed to the common aerobic bacterium, Pseudomonas fluorescens and separately to a consortium of aerobic bacteria previously shown to rapidly and extensively degrade crude oil hydrocarbons. The ATEs and naphthalene were resistant to biodegradation in laboratory experiments at room temperature for up to 119 days under conditions that led to the rapid oxidation of n-alkanes and the other major resolved components of North Sea crude oil. The higher molecular-weight ATEs, particularly those with branched chain substituents, were resistant to aerobic degradation even under biodegradation conditions defined as 'heavy'.
