Isoeugenol is a starting material for both the synthetic and biotechnological production of vanillin and vanillic acid. Nocardia iowensis DSM 45197 (formerly Nocardia species NRRL 5646) resting cells catalyze the conversion of isoeugenol to vanillic

Vanillic acid is an abundant renewable chemical useful for the biocatalytic synthesis of aromatics. The bacterium, Nocardia sp. NRRL 5646 efficiently catalyzes the decarboxylation of vanillic acid to the phenolic product, guaiacol. For purification a

The phytoestrogen daidzein was metabolized by Nocardia species NRRL 5646 to give two metabolites obtained by hydroxylation and methylation. These metabolites were spectrally characterized as 7-methoxy-4'-hydroxyisoflavone (isoformononetin) and 7,8-di

A tetrahydrobiopterin (BH4)-dependent bacterial nitric oxide synthase (NOS), designated NOSNoc, was first purified and characterized in Nocardia sp. strain NRRL 5646 in our laboratory (7). Continued pursuit of the possible roles of NOS resulted in th
