Cellulase and Xylanase Activities of Endophytic and Soil Penicillium funiculosum Strains.

Aim: To carry out a comparative study of cellulase and xylanase activities of 16 endophytic and soil Penicillium funiculosum strains.

Methods: The objects of the study were 16 endophytic and soil P. funiculosum strains from culture collection of microscopic fungi of Department of Physiology and Taxonomy of Micromycetes of D.

[Screening of Mannane-Degrading Enzymes Producers].

The aim of research was to investigate the prevalence of complex mannan-degrading enzymes among museum and freshly isolated cultures of micromycetes, actinobacteria and bacteria. It has been shown that the producers of β-mannanases mostly extracted from sources that are rich in plant residues. We detected strains of Penicillium aculeatum, P.

[THE SPECIES COMPOSITION OF MICROMYCETES ISOLATED FROM PLASTERBOARD].

Aim: To investigate the mycobiota of usual and water-resistant plasterboard of two types and to represent its ecological characteristic.

Methods: Microscopic fungi were iso- lated using the method of modeling effects of humid air and water on the plasterboard, and methods of serial dilutions and direct inoculation on agar nutrient media. Analysis of mycobiota of different types of plasterboard was conducted using the methods of quan- titative ecology.

[THE MYCOBIOTA IN STUDYING THE RESISTANCE OF GYPSUM PLASTERBOARD TO MICROSCOPIC FUNGI].

The resistance of two types of gypsum plasterboard: ordinary and water-resistant to microscopic fungi was studied. It was found that under conditions of high relative humidity and direct influence of water at constant temperature (29 ± 2) degrees C all samples of plasterboard were not resistant to fungi. Furthermore, the contaminating mycobiota of uninfected fragments of plasterboard was revealed under these conditions.

[Microscopic fungi in the air of film documents depositories].

Microscopic fungi of the studied 5 film documents depositories in Kyiv are presented by 14 species of 8 genera of the division Ascomycota (Chaetomium sp.) and the group Anamorphic fungi (13 species 7 genera). Among the isolated species there are generally accepted active destructors of various products and materials, in particular of a cine-film (A.

[Species specificity of fungi isolated from the affected rubber tires and their components].

The mycobiota of the rubber technical wares, containing different plasticizers (natural and synthetic) have been investigated. Violation of production technology and storage conditions of the staggered rubber tires, caused their deterioration by the microfungi. Twenty seven (27) species of micromycetes, related to 16 genera were isolated from the surface and internal layers of such objects and their components.

Endoglucanase-producing micromycetes capable of plant wastes degrading.

The screening study of endoglucanase producers among 58 strains 28 species 12 genera of mesophilous and thermotolerant micromycetes has been performed. Approximately 20% of investigated strains of micromycetes showed the highest endoglucanase activities (hydrolysis rates reached 0.40-0.

[Effect of heavy metal ions on the soil mycobiota in Kryvyĭ Rih region].

Ecological-taxonomic analysis of mycobiota from heavy metal polluted soils in Kryvyi Rig town and its residential suburbs are presented in this study The mycobiota consists of45 filamentous species (127 strains) belonging to 28 genera from 3 divisions. Among them Myrothecium leucotrichum was described as a new species for Ukrainian mycobiota while Absidia cylindrospora and Gongronella butleri as rare species. Paecilomyces lilacinus and P.
