Rezumat

Coordination compounds of 3d metals revealexcellent catalytic activities and the past years investigations show that the complexes play an important role in the directed synthesis of biologically active substances, including enzymes of microorganism. Two new coordination compounds, namely pentanuclear [CoIICoIII4(is)2(H3tea)4(N3)4]*1.5(H2O) (I) and mononuclear [CoII(H3tea)2](is)2 (II), have been prepared by the reaction of cobalt(II) isobutyrate is with triethanolamine (H3tea) in the presence of sodium azide in MeCN, and characterized by IR spectroscopy and X-ray analysis (Figure). The biological properties of these complexes have been tested for their ability to increase the biosynthesis of enzymes. The addition of I and II to the nutrient medium of Rhizopusarrhizus CNMN FD 03 micromycete in concentration of 5 and 10 mg/L increases biosynthesis of lipases on 43.5…78.3% (I) and 15.5…43.5% (II), depending on the applied concentration and duration of cultivation of the microorganism (Table). Our present results show that the carboxylate-triethanolamine containing compounds I and II can been used as biostimulators of the microorganism enzyme synthesis in various biotechnological processes.Table. The influence of I and II on lipolytic activity (U/mL) of Rhizopus arrhizus CNMN 03 micromycete
