Abstract
The invention relates to Arthrobacter bacterial isolates capable of degrading picric acid and related compounds to the point where no aromatic ring-containing degradation products can be detected, as determined by HPLC profiles, UV-V spectrometry, analysis of total organic carbon and mineralization of .sup.14 C-picric acid. The isolates were derived from enrichments of bacterial cultures from waste sludge by successive subculturing into medium containing picric acid as the only carbon source.
