ABDEL-MALLEK A.Y., MAZEN M.B., ALLAM A.D., HASHEM M. (1997): Specific responses of some phytopathogenic fungi to fungicides. [fungicides, phytopathogenic species, Egypt] Czech Mycology 50(1): 35-44 (published: 29th September, 1997)
abstract
Laboratory experiments were carried out to examine the effect of four fungicides on spore germinating potentialities, radial growth and survival of viable propagules in soil of five phytopathogenic fungal species. The test organisms were achieved from infected roots of wheat plants cultivated in the Assiut area, Egypt. These were: Altemaria alternata, Cochliobolus sativus, Drechslera halodes, Fusarium moniliforme and F. oxysporum. The fungicides reduced germ tube production and radial growth of all fungi, and the reduction increased with increase in concentration. The maximal reduction was recorded at 50 μg/ml. At this concentration, Homai prevented spore germination of all test species. Neither F. moniliforme nor F. oxysporum can grow on agar medium supplemented with 50 μg/ml of either Benlate or Homai. The suppressive effect of fungicides on spore survival in soil cultures was also noticed but seemed to be lower than in agar application. In certain treatments, the numbers of viable propagules of tested fungi were not significantly affected in autoclaved nor non-autoclaved soil.
MOLITORIS H.P. (1995): Fungi in biotechnology. Past, present, future. [Fungi, biotechnology, past, present, future] Czech Mycology 48(1): 53-65 (published: 16th May, 1995)
abstract
From multiple uses of fungi in early historic times, “early biotechnological processes” developed. Fungi were used here already e.g. for production of cheese, bread, wine, beer and other foodstuff. Based on these processes, fungi today have become one of the most important group of organisms in modern technology, where food, fodder and various metabolites such as antibiotics, enzymes, steroids etc. are produced on an industrial scale. An equally important role of fungi in biotechnology is also to be expected for the future where - in addition to existing uses - fungi will be increasingly used employing modern methods such as genetic engineering and will also new applications as in pollution control, biological control of pests, microbial leaching and even biotechnology.

abstract
On five localities in vallies Krížna, Koprová and Furkotská (High Tatra Mts.) we investigated the species structure of soil microscopic fungi and the similarity of mycocenosis. The arenic podzol and podzolic ranker soils were studied. The soils had low to very low acid reaction and very low content of organic matter. In the global number of isolated soil microscopic fungi species (48), the cosmopolitan genus Penicillium of the family Moniliaceae was dominantly represented. The species of the family Mucoraceae were suppressed as the result of the soil quality decreasing, which reflects the degradation of the quality of the whole environment in High Tatra Mts. The highest index of similarity – S = 0.6 – was proved between the localities in the neighboring vallies.
ŠIMONOVIČOVÁ A. (1992): Microfungal community structure in forest soil of North Slovakia. I. Similarity of mykocenosis (The Valley Tichá). Česká Mykologie 46(1-2): 99-105 (published: 1st April, 1993)
abstract
Microfungal community structure in four forest localities in the Valley Tichá in the High Tatra Mountains was studied. Podzolic and ranker soils are poor in organic matter, physically and chemically unfavourable. The pH values are lower – by 1.0 to 1.5 – than values in 1962, which means that the quality of the soils has degraded. These differences correspond with the quality of mycocenosis, which has also worsened. 41 species of soil micromycetes were isolated. The occurrence of the representatives of the genus Penicillium (fam. Moniliaceae) was the highest. The occurrence of the representatives of the family Mucoraceae was suppressed. The similarity of the neighbouring mycocenoses was higher than that of those more distant from each other.

abstract
A new record of dry rot fungus Serpula lacrimans (Wulf. ex Fr.) Schroet. on the trunk bases of two living trees of Norway Spruce Picea abies (L.) Karst. in the Botanical Garden in Průhonice near Prague is described. Differences between Serpula lacrimans and Serpula himantioides (Fr. ex Fr.) Karst. and the phytopathological significance of the new record are discussed.
FASSATIOVÁ O. (1978): Soil micromycetes in abandoned fields in Bohemian Karst. Česká Mykologie 32(4): 226-234 (published: 1978)
abstract
An analysis of soil micromycetes in two abandoned fields in the Bohemian Karst during 1976–1977 revealed 64 species in the younger field (7 years) and 50 in the older (50 years). Dominant species in both were: Penicillium albidum, Fusarium solani, Humicola grisea, Absidia cylindrospora, and Mortierella sp. (section Polycephala). The best isolation method used nylon gauze buried in soil.
JANEČKOVÁ V., FASSATIOVÁ O., DANIEL M., KŘIVANEC K. (1977): Findings of soil microscopic fungi in the Himalaya Mountains (Nepal). Česká Mykologie 31(4): 206-213 (published: 1977)
abstract
Within the framework of the 1973 Czechoslovak expedition in the Makalu Mountain region in the Himalayas (East Nepal) a total of 43 soil samples were collected for mycologic examination. Fourteen genera with 37 species of soil fungi were isolated from the samples. Though the spectrum of the isolated microscopic fungi was not wide, it contained 2 genera (Acremonium and Tolypocladium) and 15 species described for the first time amongst the Himalayan mycoflora. Some of the species were collected in the area for the second time. Among the keratinophilic microscopic fungi, Chrysosporium lucknowense was isolated. The investigation and the collection of soil samples took place at the altitudes of 1000–4900 m in the sites where the presence of terrestrial mammals was established, or direct from lair openings. The aim was to detect potentially pathogenic or keratinophilic microscopic fungi. Various species of microscopic fungi were isolated for the first time from the extreme climatic conditions of the high mountains characterized by an increased occurrence of UV radiation, great temperature fluctuations, strong air flow, a decrease in the air pressure and oxygen content and extreme abiotic and biotic factors influencing the specific existence of the organisms.
BEDNÁŘOVÁ M., FASSATIOVÁ O. (1976): Fungus contamination of algal cultures. Česká Mykologie 30(1): 33-37 (published: 1976)
abstract
Contamination in 24 algal cultures from the collection of the Department of Botany, Charles University of Prague, was determined. All cultures were contaminated. They contained fungi, bacteria, actinomycetes, in some cases fungi along with bacteria. There were isolated 10 species of fungi: Verticillium lecanii (Zimm.) Viégas, Acremonium kiliense Grütz, Penicillium notatum Westl., Penicillium sp., Aspergillus nidulans (Eidam) Wint., Aspergillus versicolor (Vuill.) Tiraboschi, Tritirachium album Limber, Cladosporium sp., Paecilomyces sp., Acremonium sp. Contaminants were able to grow even in algal cultures cultivated on mineral media. Analysis of contamination indicated that some contaminants were brought into cultures from the original environment of algae, some of them by following manipulation with cultures.
