  abstract   Mycoflora of three commercial vermiculture systems based on cattle manure derived sub­ strates and Eisenia andrei earthworms was studied using several isolation methods. A total of 172 taxa of saprotrophic micromycetes were isolated (19 taxa of Zygomycetes, 9 taxa of Ascomycetes and 144 taxa of mitosporic fungi). Aspergillus fumigatus was the most frequent microfungal species in the intestine of Eisenia andrei. In vermicuture substrates, Aspergillus flavus and Aspergillus fumigatus were among species isolated very frequently by the soil dilution method, while Rhizopus stolonifer was estimated as frequent species using the soil washing isolation technique.

HASAN H.A.H. (2000): Fungal association and deterioration of Oil-type Safflower (Carthamus tinctorius L.) seed during storage.   [safflower, mycoflora, mycotoxin, oil, protein, sugars, enzymes, germination]  Czech Mycology 52(2): 125-137   (published: 20th April, 2000)
  abstract   Different fungal species viz. Aspergillus Jiavus, A. Jumigalus, A. niger, A. sydowii, Emericella nidulans, Mucorcircinelloides and Pénicillium chrysogenum were isolated from commercial safflower seeds. The total number of fungi increased with raising the moisture content of the seeds from 15 to 25 % and reached a maximum level after 3 months of storage. Aspergillus was the dominant genus at 25°C. However, Pénicillium was dominant at 10°C. Germination of seeds significantly decreased with increasing moisture content and length of storage. Where no germination in seed at 25 % moisture content was observed after 5 months of storage at v-â 25°C, there was a perceptible increase in freefatty acidscontent, especially at high moisture and temperatures. This increase in free fatty acids positively correlated with the infestation of seeds by P. chrysogenum at 10°C, and A. flavus and A. niger at 25°C. In artificially inoculated seeds (25 % moisture content) by A. Jiavus, aflatoxin production reached their maximum level after I month and then decreased. Seed deterioration was accompanied by a corresponding rise in free fatty acids, free amino acids and soluble protein. The high levels of autolytic enzymes (amylase, cellulase, lipase and protease) detected in seed fungi clearly indicate the important role of these enzymes in seed deterioration. Also, the carcurnin and turmerol oils of safflower promoted the growth and lipase activity of A. Jiavus. Thus, the oils encourage seed infestation and did not make the safflower safe from deterioration.

GHERBAWY Y.A.M.H., ABDELZAHER H.M.A. (1999): Isolation of fungi from tomato rhizosphere and evaluation of the effect of some fungicides and biological agents on the production of cellulase enzymes by Nectria haematococca and Pythium ultimum var. ultimum.   [Biologicalcontrol, root-rot, fungicides Nectria haematococca, Pythium ultimum var. ultimum]  Czech Mycology 51(2-3): 157-170   (published: 25th May, 1999)
  abstract   Forty-five species and two species varieties belonging to twenty-six genera of fungi were isolated from 30 soil samples from the rhizosphere of tomato plants. The fungi most frequently isolated were Aspergillus flavus, A.fumigatus, A. niger, A. terreus, Gibberella fujikuroi, Nectria haematococca and Rhizopus stolonifer. Ridomil and Vitavax-captan (10, 50 and 100ppm) had no significant effects on the activity of Cl and Cₓ enzymes of Nectria haematococca. Cₓ enzyme activity was slightly increased at 10 and 50ppm, but slightly decreased at 100ppm. Vitavax-captan (10, 50 and 100ppm) significantly decreased Cl enzyme activities of N. haematococca. Cₓ enzyme activity was slightly increased at 10 and 50ppm, but at 100 ppm it showed a slightly inhibitory effect. Ridomil caused a slight increase in the activity of Cₓ and Cl enzymes by Pythium ultimum var. ultimum at low and moderate doses but the highest dose of Ridomil caused a slight reduction. Vitavax-captan slightly increased the activity of Cₓ and Cl enzymes in P. ultimum var. ultimum. Normal and sterilised filtrates of Myrothecium verrucaria, Penicillium oxalicum and Trichoderma harzianum induced a small decrease in Cl enzyme activity of Nectria haematococca. The sterilised filtrates of the three fungi tested caused greater inhibition compared to the normal filtrate. The production of Cₓ enzyme was slightly increased with normal and sterilised filtrates of Penicillium oxalicum and Trichoderma harzianum, but was significantly increased by both types of filtrates of Myrothecium verrucaria. The two types of filtrate of all fungi tested did not significantly affect the activity of Cl and Cₓ enzymes by lithium ultimum var. ultimum. Production of extracellular protein by Nectria haematococca was not significantly affected by any dose of the tested fungi cides. It was slightly increased by the two types of filtrate of the three tested fungi but significantly increased by the normal filtrate of Myrothecium verrucaria. The normal filtrate of all the fungi tested enhanced extracellular protein production to a greater extent than the sterilised filtrate. Extracellular proteins of Pythium ultimum var. ultimum were slightly increased by all doses of Vitavax-captan and low doses only of Ridomil, also two types of filtrate of all tested fungi caused a slightly increasing effect.

  abstract   The frequency of occurrence of fungi in 25 hair samples of nine kinds of sheep, collected from different localities in Saudi Arabia, was estimated using three isolation methods at 28°C. Fortyfive species and one variety representing 23 genera were isolated and the most common genera were Chrysosporium, Alternaria, Aspergillus and Penicillium. The most prevalent species of the above genera were C. indicum, C. tropicum, Alternaria alternata, Aspergillus flavus, A. fumigatus, Penicillium chrysogenum and P. oxalicum. Other fungi were also isolated with variable frequencies.

Part II: Concise information about species and varieties comprising remarks on occurrence and character of diseases in humans and animals, morphology of fungi in tissues and histopathological pictures.

BETINA V. (1986): Fungi in biotechnology-history, present times, perspectives.  Česká Mykologie 40(2): 65-73   (published: 10th May, 1986)
  abstract   A review of applications of fungi in biotechnology from the old ages to the present times is presented. Origins of vine and beer fermentation as well as leavened bread making are lost in the mist of antiquity and records of the production of Roquefort cheese go back about a thousand years. On the other hand, commercial production of yeast began in the last century and the production of single-cell proteins (SCP) was born in our century. Nowadays, fungi are further used in commercial production of enzymes, organic acids, vitamins, antibiotics and plant growth regulators, in biotransformations of steroids and antibiotics, in the ephedrin synthesis and in preparation of other pharmacologically useful substances. Great achievements were obtained by applying classical genetic methods. Possibilities of the use of protoplast fusion and recombination, gene amplification or recombinant DNA technology using restriction enzymes are discussed.

  abstract   An orientational survey of taxonomy of fungi which have been described as agents of human mycoses is given. An alphabetical list of 163 agents contains data on synonyms of the individual species and organs afflicted by them. The literature citation of the earliest paper calling attention to pathogenicity is provided. Current nomenclature of anamorph and teleomorph stages and their mutual relation is discussed.

HUBÁLEK Z. (1981): A systematic survey of dimorphic and polymorphic fungi.  Česká Mykologie 35(4): 209-226   (published: 1981)
  abstract   Various definitions of the term dimorphism in fungi are briefly discussed and a general concept is given with a suggested morphological classification of the dimorphism. Dimorphism (and polymorphism) is delimited as an environmentally controlled reversible phenotypic duality (or plurality in the case of polymorphism) in the morphogenesis of the vegetative fungal cells, which is not restricted to pathogenic species and to the mycelial-yeast transitions only. A systematic list and an alphabetical index of the fungi exhibiting the phenomena of cellular dimorphism or polymorphism are presented.
