Xylose-utilizing bacteria were numerically dominant in soils of most locations whereas xylose-and xylan-utilizing actinobacteria were minor components. Xylan-utilizing fungi constituted a major share of total microbial populations in soil samples collected at half of the sites, whereas xylan-utilizing bacteria were predominant at other sampling locations. Some of the isolates of fungi exhibited xylanase activity with a range of400–4000 U/ml, indicating great potential for their uses in paper, pulping and bioethanol industries for producing value-added products.展开更多

The experiment was conducted for three years （2012-2014）. Results showed that the application of all biopreparations and fungicide significantly reduced the number of diseased plants and the disease index. The effect of three biological products was similar. The mycological analysis of plants showed that among the fungi potentially pathogenic to strawberry, Fusarium spp., Cylindrocarpon spp., Botrytis cinerea and Alternaria were predominated. The fewest colonies of pathogenic fungi were isolated from plants treated with Trianum P.展开更多
