| ABSTRACT The demand for biodegradable composite has grown worldwide in recent years, mainly in order to reduce environmental contamination by structural materials produced from the oil industry. The objective of this study was to evaluate the growth of isolates from the edible mushroom “Shiitake” (Lentinula edodes) in substrate coconut powder-based supplemented with wheat bran, as well as to analyze the influence of fungi growing period and drying time of the colonized substrate on the mechanical properties of the composite, in order to produce a biodegradable composite. The mycelial density is not influenced by the type of hyphae of L. edodes. Drying of the composite does not influence the residual odor, depending on the isolate. The compressive strength... |

| ABSTRACT The production of plastic packing grows worldwide, resulting in the accumulation of these materials in the environment due to improper disposal and problems related to degradation. Alternatively, composites produced with agricultural residues and filamentous fungi may exhibit physical and mechanical properties similar to or greater than expanded polystyrene, depending on the fungal species and substrate of the cultivation. In the literature, no reports were found on the use of coconut powder and edible fungi of white rot in the mechanical properties of composites. Thus, the objective of this work was to select fungal isolates and to evaluate the period of cultivation in the mechanical resistance of composites produced in coconut powder... |

| ABSTRACT The evaluation of the bioremediation potential of microbial with dyes in solid and liquid culture media has been described, but prior studies have not mentioned which culture method is most appropriate for selection of microorganisms. Therefore, the aim of this work was to evaluate the bioremediation potential of filamentous fungi in liquid and solid culture media with methylene blue. The fungi isolates tested were Pleurotus ostreatoroseus (POR-SP1, POR-SP2), P. ostreatus (DF39, EF58 and EF60), Pycnoporus sanguineus (PS) and Fusidium sp. (FUS). The methylene blue concentrations tested were 0, 5, 10, and 50 mg L-1 in the solid medium and 0, 5, 25, 50, and 100 mg L-1 in the liquid medium. In the solid medium, the mycelial diameters of DF39, EF58,... |

| RESUMO Os micro-organismos endofíticos podem estimular o crescimento a depender da interação com a planta hospedeira e da disponibilidade de nutrientes no solo. O objetivo deste trabalho foi avaliar o crescimento de plantas de arroz BRS Tropical cultivadas com fungos endofíticos e níveis de adubo nitrogenado em estufa agrícola. O delineamento experimental utilizado foi inteiramente ao acaso no esquema fatorial de 4 x 4, correspondentes a quatro tratamentos (controle - sem inóculo fúngico e três isolados micorrízicos: UFLA351 - Rhizoglomus clarum, UFLA372 - Claroideoglomus etunicatum e UFLA401 - Acaulospora morrowiae) e quatro níveis de ureia (0, 100, 300 e 600 mg Kg-1 de N) com quatro repeticões. O arroz BRS Tropical foi colonizado por fungos micorrízicos... |

| Temperature is one of the main factors affecting mushrooms development and introduction in new areas. Effects of temperature (15ºC and 28ºC) and luminosity (120 and 900 lux) were evaluated for eight P. ostreatus strains in relation to precocity, yield, pileus area, stalk formation pattern, coloration and handling resistance. Genetic variability of strains was analysed by the Random Amplified Polymorphic DNA (RAPD) method. The Pos 98/37 strain was the only to yield white pileus at 28ºC - 900 lux, and grey ones at 15ºC and 120 lux. The Pos 96/05 strain, the latest, produced lead-coloured pileus at 15ºC, as did the remaining strains at this temperature. Strains cultivated at 15ºC did not differ in relation to handling resistance. At 28ºC mushrooms were less... |
