Antarctic environments can sustain a great diversity of well-adapted microorganisms known as psychrophiles or psychrotrophs. The potential of these microorganisms as a resource of enzymes able to maintain their activity and stability at low temperature for technological applications has stimulated interest in exploration and isolation of microbes from this(More)
Isolates with conidial morphologies corresponding to botryosphaeriaceous species were obtained from adult grapevines (Vitis vinifera) showing symptoms of die-back and esca in vineyards from all grape-growing regions of Uruguay and also from canes of asymptomatic mother plants in a commercial nursery. The morphological description of some of the anamorphs(More)
The main goal of this work was to detect whether Cytospora chrysosperma and Fusicoccum eucalypti are present as endophytes of symptomless hypocotyls, cotyledons, flowers, capsules, peduncles of flowers in order to interpret an earlier finding of their presence in seeds, seedling stems and twigs of E. globulus. Segments from these organs as well as from bark(More)
The surface coverage of certain dry fermented sausages such as Italian salami by some species of Penicillium provides their characteristic flavor and other beneficial properties. One of them is the protective effect by means of a uniform film of white mold against undesirable microorganisms. The aim of this work was to identify and to isolate the fungal(More)
Forty three thermophilic, thermotolerant and mesophilic fungal species and nematodes from five trophic groups were found in four compost types. Aspergillus fumigatus and A. niger were the most frequent species. Plant pathogenic fungi viz. Fusarium oxysporum, F. acuminatum, F. nygamai and F. solani were found in some of the composts in low frequency. The(More)
Apple, pear and peach orchards are usually planted in close proximity, and they might share pathogenic fungal species affecting different plant organs. In particular, species of Botryosphaeriaceae have been indicated as responsible for wood diseases in these fruit species. Symptoms frequently observed in Uruguay include papyraceous cankers in apple trunks,(More)
