25. Valor nutricional de cogumelos cultivados no Brasil. / Nutritional value of mushrooms cultivated in Brazil.
Very little is known regarding the quality of the edible mushrooms cultivated in Brazil, especially with respect to their nutritional value. Considering this and the constant interest of the consumer in natural vitamin sources, the present work evaluated methodologies for the determination of vitamins B1, B2, B6, B12, H and PP and developed and validated ana

26. Cloning of a chitinase gene from Ewingella americana, a pathogen of the cultivated mushroom, Agaricus bisporus
O gene que codifica uma quitinase (EC 3.2.1.14) foi isolado de Ewingella americana, recentemente descrita como patógeno do cogumelo Agaricus bisporus. Este gene, denominado chiA (EMBL/Genebank/DDBJ número de acesso X9061), foi clonado e selecionado a partir de livraria genômica construída por digestão do DNA de E. americana com HindIII e ligação em pl

27. Secagem de cogumelo (Agaricus bisporus)
Desenvolveu-se um estudo experimental de secagem do cogumelo, tipo champignon (Agaricus bisporus). As corridas experimentais foram conduzidas em secador hermético com corrente de ar a temperatura de 35°C, com umidade relativa média de 9,8% e velocidade de l,05m/s. Na faixa de umidade de 95-12% (em base seca), a curva de secagem não apresentou a fase de t

28. Basidiospore Numbers in Agaricus bisporus (Lange) Imbach
The number of spores per basidium in the cultivated mushroom Agaricus bisporus can be readily determined using the light microscope.

29. Ethylene Production by Axenic Fruiting Cultures of Agaricus bisporus
Axenic cultures of Agaricus bisporus were used to show that the rise in ethylene production during fruiting derives from its own metabolism.

30. Double-stranded ribonucleic acid in Agaricus bisporus.
Double-stranded ribonucleic acid present in virus-infected mushrooms of Agaricus bisporus has been resolved through polyacrylamide gel electrophoresis into six molecular-weight forms. Identification of these six double-stranded ribonucleic acids in mushrooms by this procedure has proven to be a useful and diagnostic method for viral infection in the cultivat

31. A Selective Medium for Quantitative Reisolation of Trichoderma harzianum from Agaricus bisporus Compost
We adapted a selective medium, previously developed for reisolation of Trichoderma spp. from soil, for quantitative determination of growth of T. harzianum from commercial Agaricus bisporus composts. This medium enables comparisons of aggressive (sensu inhibition of A. bisporus yield) with nonaggressive T. harzianum groups. The resulting medium contains the

32. A Fruiting Body Tissue Method for Efficient Agrobacterium-Mediated Transformation of Agaricus bisporus
We describe a modified Agrobacterium-mediated method for the efficient transformation of Agaricus bisporus. Salient features of this procedure include cocultivation of Agrobacterium and fruiting body gill tissue and use of a vector with a homologous promoter. This method offers new prospects for the genetic manipulation of this commercially important mushroo

33. Investigation of Mitochondrial Transmission in Selected Matings between Homokaryons from Commercial and Wild-Collected Isolates of Agaricus bisporus (= Agaricus brunnescens)
Ten heterokaryons of Agaricus bisporus (= Agaricus brunnescens) were shown to carry four different mitochondrial (mt) genotypes by analysis of mt restriction fragment length polymorphisms (RFLPs). Fifteen homokaryons derived from these strains were used to investigate mt inheritance in A. bisporus. One hundred eighty-nine pairings were performed in 25 differ

34. Effect of Metabolites Produced by Trichoderma harzianum Biotypes and Agaricus bisporus on Their Respective Growth Radii in Culture
Trichoderma harzianum biotypes Th1, Th2, and Th3 produced volatile metabolites in vitro which had similar fungistatic effects on the growth of Agaricus bisporus. Metabolites present in agar colonized by these strains also inhibited mycelial growth of A. bisporus, although the reduction in growth was less in the presence of metabolites produced by biotype Th2

35. Study on development of Agaricus bisporus by fluorescent microscopy and scanning electron microscopy.
Two strains of Agaricus bisporus have been investigated by fluorescent microscopy and scanning electron microscopy. Somatic nuclei, stained with auramin O and examined by fluorescent microscopy, appear to be randomly distributed, divide asynchronously, and assume a nonclassical or "two-track" configuration during mitotic metaphase. A similar configuration ha

36. Scanning Electron Microscope Studies of Interactions between Agaricus bisporus (Lang) Sing Hyphae and Bacteria in Casing Soil
Relationships between the hyphae of Agaricus bisporus (Lang) Sing and bacteria from the mushroom bed casing layer were examined with a scanning electron microscope. Hyphae growing in the casing layer differed morphologically from compost-grown hyphae. Whereas the compost contained thin single hyphae surrounded by calcium oxalate crystals, the casing layer co
