A stepwise screening of bacterial producers of xylanases isolated from the forest soil in Moscow oblast, and also the taxonomic identification of the microorganisms based on the analysis of the 16S RNA gene sequences have been performed. An approach to the selection of the most active producers was suggested, and this selection was carried out resulting in 4 producing strains. Interestingly, the species to which 2 of the selected strains (Paenibacillus jamilae and P. brasilensis) belong were described as producers of xylanolytic enzymes for the first time, and the characteristics of those xylanases have not yet been studied. The new strains can serve as a source of genes for the construction of high-efficient xylanase producers.
