[Xylanase activity of phytopathogenic and endophytic strains of Ceratocystis sp].

A comparative analysis of xylanase activity of 36 phytopathogenic and endophytic Ceratocystis sp. strains was conducted. The rate of their linear growth on the medium with xylan was studied.

[Mycobiota of Quercus robur L. from the oak forest in the Zhytomyr region].

Different organs of 155 samples of conditionally healthy and sick oaks were examined for mycological contamination. The isolated microscopic fungi belonged to 129 species of different taxonomic groups. The pathogenic complex was represented by 30 fungi species, however most of these species were isolated in single cases.

[Cellulase activity of Ceratocystis sp. of different trophic groups].

A comparative analysis of cellulase activity of 36 fungal strains of phytopathogenic and endophytic Ceratocystis sp. was conducted. The rate of their linear growth on the media with carboxymethylcellulose was studied.
