TRANSFORMATION OF FERULIC ACID BY SOIL BACTERIA NOCARDIA PROVIDES VARIOUS VALUABLE PHENOLIC-COMPOUNDS

Nocardia autotrophica was grown in a medium containing ferulic acid an d C-14-ferulic acid, labelled in various parts of a particle as a main carbon source. After incubation, the products were analyzed by thin l ayer, high performance liquid and gas chromatography and by IR and NMR spectra methods. The products detected were caffeic acid, catechol, c oniferyl alcohol, eugenol, guaiacol, hydrocaffeic acid, isoeugenol, is oferulic acid, isovanillic acid, p-hydroxybenzoic acid, protocatechuic acid and aldehyde, vanillic acid, and vinylguaiacol. A liberation of (CO2)-C-14 during cultivation was noticed.
