ABSTRACT:
Nitrogen-containing phenol compounds are biodegradable by a consortium of microorganisms. The consortium was isolated from waste sludge by successive subculturing into medium containing picric acid as the only carbon source. During the period of degradation, picric acid was seen to degrade to a colored intermediate which later disappeared. UV-Vis spectrometry, HPLC and GC-mass spectrophotometry showed that the entire ring structure was eventually destroyed. The consortium contains microorganisms from the genera Arthrobacter, Avrobacterium and Pseudomonas.
