Popis: Lyophilized cells of Rhodococcus R 312 (CBS 717.73) can be employed as an easy-to-use biocatalyst for the biocatalytic hydrolysis of nitriles to furnish the corresponding carboxamides or acids on a preparative scale. The following practical aspects are advantageous: (i) Fermentation yields a high biomass (∼10 g dry cell weight l−1), (ii) enzyme induction is not required, (iii) a maximum of activity is obtained at the late exponential growth phase (25.7 μmol min−1 mg−1), which can be monitored by a simple photometic assay and (iv) the cells can be stored at +4°C for several months without significant loss of activity.
