Biodegradation | SpotlightMicrobial Degradation of Pyridine: a Complete Pathway in Arthrobacter sp. Strain 68b DecipheredThe biodegradation pathway of pyridine, a notorious toxicant, is relatively unexplored, as no genetic data related to this process have ever been presented. In this paper, we describe the plasmid-borne pyr gene cluster, which includes the complete set of genes responsible for the degradation of pyridine. A key enzyme, the monooxygenase PyrA, which is responsible for the first step of the catabolic pathway, performs an oxidative...
BiodegradationBiodegradation of Ephedrine Isomers by Arthrobacter sp. Strain TS-15: Discovery of Novel Ephedrine and Pseudoephedrine DehydrogenasesArthrobacter sp. TS-15 is a newly isolated bacterium with the unique ability to degrade ephedrine isomers. The initiating steps of the novel metabolic pathway are described. Arthrobacter sp. TS-15 and its isolated ephedrine-oxidizing enzymes have potential for use in decontamination and synthetic applications.
