13. Shelf-life increase of fresh mushrooms Pleurotus sajor-caju using gamma radiation. / Aumento da vida útil de cogumelos Pleurotus sajor-caju in natura com aplicação de radiação gama
The production and consumption of edible mushrooms has been increasing in the last years due to its nutritional composition and sensory quality. The irradiation of mushrooms has been used with the purpose of maintaining the fresh product characteristics during shelf-life. The present study evaluated the effect of different radiation doses on the conservation

14. Antimicrobial activity of extracts and fractions from culture in vitro of Lentinula edodes against Xanthomonas axonopodis pv passiflorae, Guignardia citricarpa, Colletotrichum sublineolum and Tobacco mosaic virus / Atividade antimicrobiana de extratos e frações do cultivo in vitro de Lentinula edodes contra Xanthomonas axonopodis pv passiflorae, Guignardia citricarpa, Colletotrichum sublineolum e Tobacco mo
Edible mushrooms contain functional compounds, such as proteins and glucans, which exhibit antimicrobial potential against bacteria, fungi and antiviral activity. The aim of this work was to identify extracts from submerged mycelium of Lentinula edodes with antimicrobial properties against phytopathogens. Two strains of L. edodes were grown in small scale in

15. Indução de resistência em plantas de berinjela e tomate por Lentinula edodes e Agaricus blazei contra bactérias causadoras de murcha (Ralstonia solanacearum) e cancro (Clavibacter michiganensis subsp. michiganensis) / Induced resistance by Lentinula edodes and Agaricus blazei in tomato plant and eggplant against bacterial wilt (Ralstonia solanacearum) solanacearum) and bacterial canker (Clavibacter michiganensis subsp. michiganensis)
Devido ao aumento da preocupação com o impacto dos agrotóxicos no meio ambiente e na saúde humana, busca-se uma agricultura sustentável. É no âmbito dessa questão que a resistência induzida torna-se uma ferramenta fundamental no manejo integrado de doenças e indispensável para uma nova agricultura, mais racional e sustentável. Dentre os diversos

16. 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

17. Produção de Pleurotus sajor-caju em bagaço de cana-de-açúcar lavado e o uso de aditivos visando sua conservação "in natura". / Production of Pleurotus sajor-caju in washed sugar cane bagasse and the fresh mushroomsshelf life evaluation by treatment with diferent solutions.
Traditionally, the cultivation of edible mushroom Pleurotus sajor-caju or hiratake has been carried out on different composted and pasteurized agricultural residues. They are usually sold in natura and according to the storage conditions the mushroomsshelf life varies from 3 to 7 days. The objectives of this study were to investigate the traditional pr

18. Avaliação da mutagenicidade e antimutagenicidade de extratos aquosos e orgânicos do Agaricus blazei Murill (Cogumelo do Sol ) linhagem AB97/11, in vitro
Existem várias espécies de cogumelos, sendo que muitas delas são utilizadas na medicina e na alimentação. O Agaricus blazei Murrill é uma espécie nativa do Brasil, muito consumida devido a suas propriedades medicinais. No presente trabalho a avaliação da atividade mutagênica e antimutagênica de extratos aquosos da linhagem AB97/11, na fase jovem e

19. Isolation of amoebae from edible mushrooms.
Isolation of amoebae from the surface and internal tissues of edible mushrooms was investigated. Samples tested over a 3-year period included mushrooms cultivated from six geographic localities. Of 168 mushroom surfaces tested, 161 (96%) yielded amoebae. Of 166 samples of internal stalk and cap tissues tested, only 1 yielded amoebae.

20. Growth potential of Clostridium botulinum in fresh mushrooms packaged in semipermeable plastic film.
Fresh mushrooms (Agaricus bisporus) were inoculated in the stem, gill, or cap with Clostridium botulinum spores. They were placed with uninoculated mushrooms in paper board trays, which were then covered and sealed in a polyvinyl chloride stretch film to simulate prepackaged mushrooms available at retail stores. When incubated at 20 C, botulinum toxin could

21. Pathogenicity of a fungus resembling Wangiella dermatitidis isolated from edible mushrooms.
A fungus resembling the human pathogen Wangiella dermatitidis (Kano) McGinnis, a dematiaceous hyphomycete, was recovered from imported desiccated "black fungus" mushrooms (Auricularia polytrichia (Mont.) Sacc.), a food item popular in Far Eastern cuisine. Except for its conidia, which are mostly reniform to allantoid rather than ovoid as is characteristic fo

22. Restriction Fragment Length Polymorphisms in the Mushrooms Agaricus brunnescens and Agaricus bitorquis
Two Agaricus species, A. brunnescens (a commercial mushroom) and A. bitorquis (a wild, edible species), were examined for restriction fragment length polymorphisms. EcoRI-digested nuclear DNA from isolates of both species were cloned in plasmid vector pUC18. Ten random recombinant clones were used in Southern DNA-DNA hybridizations to probe EcoRI-digested DN

23. Antigens in tea-beverage prime human Vγ2Vδ2 T cells in vitro and in vivo for memory and nonmemory antibacterial cytokine responses
Human γδ T cells mediate innate immunity to microbes via T cell receptor-dependent recognition of unprocessed antigens with conserved molecular patterns. These nonpeptide alkylamine antigens are shared by tumor cells, bacteria, parasites, and fungi but also by edible plant products such as tea, apples, mushrooms, and wine. Here we show that priming of γδ

24. Linkage of mating-type loci distinguishes bipolar from tetrapolar mating in basidiomycetous smut fungi.
Sexual compatibility requires self vs. non-self recognition. Genetically, two compatibility or mating-type systems govern recognition in heterothallic basidiomycete fungi such as the edible and woodrotting mushrooms and the economically important rust and smut phytopathogens. A bipolar system is defined by a single genetic locus (MAT) that can have two or mu
