The identification of the diversity of microscopic fungi of lithobiont communities of the Argentine Islands in specimens collected during the 22nd Ukrainian Antarctic Expedition was the purpose of this work. Samples of rock, soil, mosses and lichens of rock micro-habitats of “Crustose lichen sub-formation and fruticose lichen and moss cushion sub-formation” were used in the work. These samples were used for extracting and cultivation of filamentous fungi on dense nutrient media. Determination of physiological and biochemical characteristics and identification of yeast-like fungi were performed using a microbiological analyser ‘Vitek-2’ (‘Bio Merieux’, France). Cultivation of microorganisms was carried out at temperatures from +2 to +37 °C. In results cultures of microscopic fungi of Zygomycota (Mucor circinelloides), Ascomycota (species of the genera cf. Tlielebolus, Talaromyces), representatives of the Anamorphic fungi group (Geomyces pannorum, species of the genera Alternaria, Acremonium, Aspergillus, Penicillium, and Cladosporium) were isolated from Antarctic samples. Microscopic fungi Penicillium spp. were dominated after the frequency in the studied samples (54.5%). Rhodotorula rubra and Candida sp. among isolated yeast fungi, and dark pigmented fungi represented by Aureobasidium pulhdans and Exophiala spp. were identified. The biological properties of a number of isolated fungi (the potential ability to synthesise important biologically active substances: melanins, carotenoids, lipids) are characterised. Mycobiota of rock communities of Argentine Islands is rich on filamentous and yeast fungi similarly to other regions of Antarctica. A number of fungi investigated are potentially able to synthesise biologically active substances. The dark pigmented species of the genera Cladosporium, Exophiala, Aureobasidium pulhdans, capable of melanin synthesis; ‘red’ yeast Rhodotorula rubra (carotenoid producers and resistant to toxic metals); Mucor circinelloides and Geomyces pannorum, lipid producers, are among these fungi. Yeast-like fungi assimilated a wide range of carbohydrates, which will allow them to be further used for cultivation in laboratory and process conditions. The collection of technologically promising strains of microorganisms, part of the Culture Collection of Fungi at Taras Shevchenko National University of Kyiv (Ukraine), is updated with isolated species (strains) of filamentous fungi and yeast – potential producers of biologically active substances, obtained within this study.

Ascomycota is a microscopic fungi and a fraction of macroscopic, unicellular and multicellular fungi. The research of Ascomycota phylum macroscopic fungi inventory research aims to determine the type macroscopic fungi of Ascomycota phylum members in Tanjungpura University Area, Pontianak, West Borneo. The sample was taken by using Cruise Method and identified by matching morphological characteristics of the specimens with the identification book. Ascomycota  identification of macroscopic fungi samples of Ascomycota phylum based on morphological characteristics with the identification books. The results study found have 3 macroscopic fungi species consisting of 2 classes, 2 orders, 2 families, and 2 genera. In addition, Ascomycota found in Tanjungpura University Area, Pontianak, West Borneo, grow mostly on the substrate originated from dead trees.

Abstract Localities in Castanea sativa Mill. plantations were visited in a study aimed at identifying the mycoflora of C. sativa in Slovakia [excluding Cryphonectria parasitica (Murr.), Barr for which much data is available]. Samples from chestnut tree branches and stems were examined visually and microscopically. Seven species of microfungi were recorded, three with their anamorphs. Coryneum modonium (Sacc.) Griffon & Maubl. and Phomopsis castaneae Woron. were the most common. Libertella quercina Tul. & C. Tul. was identified in both states (anamorph and teleomorph) at two new localities. The records of Gloniopsis praelonga (Schwein.) Underw. & Earle and Dothidotthia celtidis (Ellis & Everh.) M. E. Barr are the first for Slovakia. These species were rare, found only in one locality. Two microscopic fungi were detected: Valsa ambiens (Pers.) Fr. [Cytospora ambiens (Nitschke) Sacc.] and Diplodina castaneae Prill. & Delacr.

The article presents the results of complex study of cotton-seed cake from the Republic of Tajikistan, including the determination of content of mycotoxins, the analysis of exposure to microscopic fungi and the assessment of the potential of their toxin formation. The ability to produce mycotoxins was established for 11 species of micromycetes belonging to the genus Aspergillus, Penicillium, Fusarium, Scop-ulariopsis, and Trichothecium. Alternariol, zearalenone, fu-monisins, aflatoxin B1, sterigmatocystin, ochratoxin A, citrinin and emodin were found in the composition of the cotton-seed cake. Prospects for further research and the practical significance of the results are discussed.

In this work we studied the effect of microscopic soil fungi on some lather samples. The species composition of micromycetes inhabiting the samples under study was revealed, and an assessment of the fungal resistance of the materials under study was given. In the process of work, species of microscopic soil fungi were isolated and identified from the soil. In order to determine the degree of resistance to fungi for the infection of samples, a water-spore suspension was obtained. The leather materials were partially destroyed by microscopic fungi, and mold resistance ranged from 2 to 3 on a 5-point scale.
