Rezumat

Coordination compounds of 3d metals revealed excellent catalytic activities in the past years and these complexes play an important role in the directed synthesis of biologically active substances, including the production of enzymes by microorganisms. A new coordination compound, [Co(H3tea)2](NO3)2 (1), were prepared by the reaction of cobalt(II) isobutyrate with triethanolamine (H3tea) in the presence of Dy(NO3)3·6H2O in MeCN, and characterized by IR spectroscopy and a single-crystal X-ray diffraction studies. The biological properties of this complex have been tested for its ability to increase the biosynthesis of enzymes. The addition of 1 to the nutrient medium of Rhizopus arrhizus CNMN FD 03 micromycete in concentration of 5 and 10 mg L increases biosynthesis of lipases on 54…91.3% depending on the applied concentration and duration of cultivation of the microorganism (Table). Our present results show that the Co(II) triethanolamine containing compounds can been used as biostimulators of the microorganism enzyme synthesis in various biotechnological processes. Table.
