Novel intermediates of acenaphthylene degradation by Rhizobium sp. strain CU-A1: evidence for naphthalene-1,8-dicarboxylic acid metabolism.

The acenaphthylene-degrading bacterium Rhizobium sp. strain CU-A1 was isolated from petroleum-contaminated soil in Thailand. This strain was able to degrade 600 mg/liter acenaphthylene completely within three days.
