Biotechnological potential of xylotrophic macromycetes distributed in Azerbaijan as producers of polysaccharides

Abstract

The purpose of the presented work was to determine the species composition of the mycobiota of xylotropic macromycetes distributed on trees in the territory of the Republic of Azerbaijan, the creation of a collection consisting of cultures of the species participating in its formation, and the biotechnological potential of the species belonging to the genus Ganoderma included in the collection as producers of polysaccharides. It has become clear that 72 species belonging to 40 genera participate in the formation of the xylomicobiota of trees distributed in the conditions of Azerbaijan, 4 of which belong to the genus Ganoderma. Although species belonging to the genus Ganoderma differ from one another in terms of growth rates, the amount of polysaccharides they produce, as well as their quality indicators, strains belonging to G. applanatum and G. lucidum differed from the others in all indicators. This difference is reflected in both the quantitative and qualitative characteristics of the polysaccharides they produce. Thus, the total amount of polysaccharides they formed was 1.4-2.2 times higher than that of others, and the share of 1-3-β-glucosidic bonds in their composition was relatively high. This is a serious basis for their use for practical purposes in the future.
