The Paulownia spp. is a fast growing variety of deciduous tree that belongs to the Paulowniaceae family. These trees are used
to produce biomass and reduce carbon dioxide concentrations in the atmosphere. Paulownia spp. leaves have a high content
of protein, fats, sugar and nitrogen, phosphorus, potassium (NPP). The purpose of this study was to determine the functional
and genetic diversity of the microbial of the Paulownia spp. Next Generation Sequencing (NGS) and Biolog EcoPlates were
used to evaluate microbial diversity. The research materials were leaves of trees Paulownia spp. Plant samples were taken from
Podkampinos (a plantation established on arable soil) and OtrÃ?Â?Ã?Â?Ã?Â?Ã?Â?busy (a plantation established on degraded soil). The samples
were the clones of the same hybrid Paulownia elongata and Paulownia fortunei. Additional hybrid of Paulownia tomentosa
and Paulownia fortunei was included. The functional analysis was carried out using statistical methods: cluster analysis by
Ward���¢��������s method, taking into account Euclidean square of distance. Moreover, the Shannon-Wiener (H') biodiversity index,
R Richness, E Evenness, and AWCD (average well color development) were calculated. The obtained sequences were subject
to bioinformatics analyses, such as clustering and separation of operational taxonomic units (OTU). The samples from the
plantation established on degraded soli revealed that the most dominant phylum was Bacteroidetes, whereas from the arable
soil, Proteobacteria. Comparisons of carbon source utilization and the diversity indices showed differences in the microbial
community of composition. Among the five carbon sources studied, carbohydrates were the most frequently used group of compounds.
