Abstract: | The impact of symbiotrophic basidiomycetes on the abundance and structure of the soil saprotrophic bacterial complex of the
mycorhizosphere and hyphosphere of 10 species of symbiotrophic basidiomycetes in natural conditions is studied. Compared to
the reference soil, one can observe a significant increase in bacterial abundance in the mycirhizosphere and hyphosphere of
basidiomycetes. The analysis of the taxonomical structure of bacterial complexes showed that Pseudomonas prevail in the mycorhyzosphere and Bacillus, in the rhizosphere and reference soil. Bacterial complexes of the hyphosphere and those in reference soil showed greater
similarity to each other than either of them does to the mycorhizosphere. This fact implies the selective impact of the mycorhizosphere
on soil bacteria. |
