16、ioaugmentation agents.Performance also dependson the availability of rate-limiting nutrients and the suscepti-bility of the target crude oil or refined product to microbialdegradation.As oil consists of hundreds or more compounds,many of which require different conditions or different micro-organisms to degrade,oil biodegradation should not be con-sidered a single process.Oil biodegradation should at leastconsider the aliphatics separate from the aromatic compounds.Other classes of compounds oft
