摘要

Sequence and terminal restriction fragment length polymorphism (T-RFLP) analyses revealed multiple alkB gene copies/cell in soil bacterial isolates and an apparently high genetic mobility among various phylogenetic groups. Identifying alkane degraders by alkB terminal restriction fragments (T-RFs) and sequences is strongly biased, as the phylogenetic trees based on 16S rRNA and alkB gene sequences were highly inconsistent.
