Bioremediation

Which microorganism is known to degrade aromatic hydrocarbons?

Pseudomonas putida strains such as KT2440 certified HV1 safety, mt-2 and F1 embody archetypal aerobic degraders of monoaromatic and polycyclic aromatic hydrocarbons due to extraordinary metabolic versatility conferred by large genome 6.2 megabases encoding more than 80 oxygenases and multiple catabolic plasmids including TOL plasmid pWW0 carrying upper pathway xylCMABN converting toluene and xylene to benzoate via xylene monooxygenase multicomponent system and meta-cleavage lower pathway xylXYZLTEGFJKIH, and NAH7 plasmid encoding naphthalene dioxygenase nahAc. Enzymatic repertoire includes tol
