Dimethylformamide is a novel nitrilase inducer in Rhodococcus rhodochrous

Author: Chhiba, Varsha P ; Mathiba, Kgama ; Van der Westhuyzen, Christiaan W ; Steenkamp, Paul A ; Rashamuse, JK ; Stoychev, Stoyan H ; Bode, ML ; Brady, D Date: Dec 2018 Nitrilases are of commercial interest in the selective synthesis of carboxylic acids from nitriles. Nitrilase induction was achieved here in three bacterial strains through the incorporation of a previously unrecognised and inexpensive nitrilase ... Read more
Gas chromatographic profiling of the biocatalytic conversion of sclareol to ambradiol by Hyphozyma roseoniger

Author: Ncube, EN ; Mathiba, Kgama ; Steenkamp, Lucia H ; Dubery, IA Date: Oct 2021 Hyphozyma roseoniger is a filamentous yeast used for its biocatalytic ability to convert sclareol, a plant diterpenoid to ambradiol, an intermediate to ambrafuran, which is a sought-after fixative in the perfume industry. Metabolite profiling ... Read more
Hydrolysis of nitriles by soil bacteria: variation with soil origin

Author: Rapheeha, OKL ; Roux-van der Merwe, MP ; Badenhorst, J ; Chhiba, Varsha P ; Bode, ML ; Mathiba, Kgama ; Brady, D Date: Mar 2017 The aim of this study was to explore bacterial soil diversity for nitrile biocatalysts, in particular, those for hydrolysis of ß-substituted nitriles, to the corresponding carboxamides and acids that may be incorporated into peptidomimetics. ...
