Long-range (1)H-(15)N heteronuclear shift correlation at natural abundance: a tool to study benzothiazole biodegradation by two rhodococcus strains.
The biodegradation of benzothiazole and 2-hydroxybenzothiazole by two strains of Rhodococcus was monitored by reversed phase high-pressure liquid chromatography and by (1)H nuclear magnetic resonance (NMR). Both xenobiotics were biotransformed into a hydroxylated derivative of 2-hydroxybenzothiazole by these two strains. The chemical structure of this metabolite was determined by a new NMR methodology: long-range (1)H-(15)N heteronuclear shift correlation without any previous (15)N enrichment of the compound. This powerful NMR tool allowed us to assign the metabolite structure to 2,6-dihydroxybenzothiazole.
