Summary A bacterium utilizing the alkaloid (−)-ephedrine as its sole source of carbon was isolated by an enrichment-culture technique from soil supplemented with (−)-ephedrine hydrochloride. The bacterium was identified asArthrobacter globiformis by morphological and physiological studies. The following metabolites of (−)-ephedrine degradation were isolated from the culture fluid: methylamine, phenylacetylcarbinol (1-hydroxy-2-oxo-1-phenyl-propane), methylbenzoylcarbinol (2-hydroxy-1-oxo-1-phenyl-propane), acetaldehyde, benzoic acid, pyrocatechol, and cis,cis-muconic acid. A pathway for the bacterial degradation of (−)-ephedrine has been proposed.
