| Como parte do levantamento dos fungos xilófagos poliporóides da mata de Araucária do Parque Nacional de Aparados da Serra - RS, apresenta-se neste trabalho o estudo dos representantes de dois gêneros estreitamente relacionados, Rigidoporus e Flaviporus. Do gênero Rigidoporus foram identificados três espécies: R. lineatus (Pers.) Ryv, R. ulmarius (Sow. ex Fr.) Imazeki, R. umbonatipes Rajch., esta última constitui citação nova para o Brasil. O gênero Flaviporus também está representado por três espécies: F. subhydrophilus (Speg.) Rajch & Wright, F. venustus David & Rajch e Flaviporus sp. São apresentadas chaves para a identificação, descrições, comentários e ilustrações das espécies estudadas. |

| Os sistemas florestais de Santa Catarina são poucos estudados em relação à diversidade de Agaricales. O objetivo deste trabalho foi determinar e comparar a diversidade de Agaricales em dois sistemas florestais, no município de Joinville, SC. Parcelas de 20×20 m foram estabelecidas: três em Floresta Ombrófila Densa e três em plantações de Pinus. Basidiomas de fungos agaricóides foram coletados em janeiro, março, maio, julho, setembro e novembro/2004. Foram identificadas 40 espécies, 31 na Floresta e 10 nas plantações. A família mais representada foi Tricholomataceae, com 48% das espécies registradas na Floresta. As espécies com maior abundância relativa foram Camarophyllus buccinulus (41%) na Floresta e Lactarius cf. fragilis (53%) nas plantações. As mesmas... |

| The aim of this work was to study the production of compounds with antioxidant activity by Pycnoporus sanguineus when cultivated in submerged fermentation using a potato dextrose broth plus peptone medium. The study evaluated the biomass production, glucose consumption, variation of medium pH and antioxidant activity. The antioxidant potential was tested through the DPPH method and β-carotene / linoleic acid system with extracts obtained from the mycelium at different times of cultivation (5, 10, 15, 20, 25 and 30 days). Maximum kinetic values of specific growth rate (0.289 day-1), biomass productivity (0.698 g.L-1.day-1) and the yield of glucose conversion into biomass (26.24 g.g-1) were obtained during the exponential growth phase. The highest... |

| The aim of this work was the use of Pleurotus ostreatus and Pleurotus sajor-caju for the previous lignocellulolytic decomposition of banana tree leaf straw and the further use of the degraded straw as substrate for the culture of Agaricus blazei. For optimising the production of A. blazei in terms of yield (Y%) and biological efficiency (BE%), adjustments to the composition of the substrate were evaluated in a 2(5) experimental design. The following components were tested in relation to % of substrate dry mass: urea (1 and 10%), rice bran (10 or 20%) or ammonium sulphate (0 or 10%), inoculum (10 or 20%) and the casing material (subsoil or burned rice husks). The best results (79.71 Y% and 6.73 BE%) were found when the substrate containing 10% of rice bran,... |

| The edible mushroom Oudemansiella canarii (Jungh.) Höhn is common in the Brazilian territory, being found in different biomas, where they colonize several plant species. In this study, the O. canarii cultivation was evaluated in polypropilene bags containing sugar-cane bagasse (200 g) or eucalyptus sawdust (200 g) supplemented with wheat bran (50 g). The composts were sterilized at 121ºC for 1 hour, after cooling they were inoculated with 3 g of spawn and then remained incubated at 25ºC until the basidiomata primordia formation. The mushrooms, harvested after the pilei opening, presented varied sizes reaching 9 cm of diameter and 10 cm of height. The fresh mushrooms presented mild taste and soft consistency. When kept at 4ºC, they maintained good... |

| This study presents new and alternative fungal strains for the production of ligninolytic enzymes which have great potential to use in industrial and biotechnological processes. Thirty autochthonous fungal strains were harvested from Bornova-Izmir in Turkiye. In the fresh fruitbody extracts laccase, manganese peroxidase and lignin peroxidase activities, which are the principal enzymes responsible for ligninocellulose degradation by Basidiomycetes, were screened. Spores of some of the basidiomycetes species such as Cortinarius sp., Trametes versicolor, Pleurotus ostreatus, Abortiporus biennis, Lyophyllum subglobisporium, Ramaria stricta, Ganoderma carnosum, Lactarius delicious ve Lepista nuda were isolated and investigated optimum cultivation conditions in... |

| Wood rotting Basidiomycetes collected in the "Estação Ecológica do Noroeste Paulista", São José do Rio Preto, São Paulo State, Brazil, concerning Aphyllophorales order and identified as Coriolopsis byrsina SXS16, Lentinus strigellus SXS355, Lentinus sp SXS48, Picnoporus sanguineus SXS 43 and Phellinus rimosus SXS47 were tested for ligninases production by solid state fermentation (SSF) using wheat bran or rice straw as culture media. C. byrsina produced the highest laccase (200 U mL-1) and Lentinus sp produced the highest activities of manganese peroxidase (MnP) and lignin peroxidase (LiP) (7 and 8 U mL-1, respectively), when cultivated on wheat bran. The effect of N addition on enzyme production was studied in medium containing rice straw and the data... |

| Studies have indicated the capacity of basidiomycetes to degrade recalcitrant organopollutants. However, the age of the fungal inoculum to obtain a more effective degradation has not been defined. The criterion used is total colonization of the substrate. Psilocybe castanella CCB444 and Lentinus crinitus CCB274 have been evaluated in soils containing hexachlorobenzene. In the present study, the physiological conditions of the fungal inocula were characterized on solid substrate (sugarcane bagasse, starch and soy flour). Colonization of the substrate, loss of organic matter, pH variation, organic carbon, total nitrogen, fungal biomass and enzymatic activity were evaluated over 30 days of incubation. Colonization of the substrate was almost complete after 20... |
