Abstract

The influence of coordination compounds of cobalt, copper and zinc with oxime ligands on the biosynthesis of exocellular hydrolases of fungal strains Aspergillus niger CNMN FD 10 – producer of cellulases and xylanases, Trichoderma koningii Oudemans CNMN FD 15 and Fusarium gibbosum CNMN 12 – producers of proteases was studied. The differential effect of tested compounds on the biosynthesis of hydrolases, depending on the origin of micromycetes and the synthesized enzymatic systems was established. Keywords: cellulases, xylanases, proteases, coordination compounds, micromycetes, directed synthesis.
