Contents of folates in edible mushrooms commercialised in the city of Campinas, São Paulo, Brazil Ciênc. Tecnol. Aliment.
Furlani,Regina Prado Zanes; Godoy,Helena Teixeira.
In this study, folates were evaluated in the main species of mushroom cultivated in Brazil. The species analysed were Agaricus bisporus (button mushroom), Lentinula edodes (shiitake) and Pleorotus ostreatus (shimeji). The five main forms of folate found in foods were determined: tetrahydrofolic acid (THFA), 10-methyl folic acid (10MFA), 5-methyl tetrahydrofolic acid (5MTHFA), 10-formyl folic acid (10FFA) and 5-formy tetrahydrofolic acid (5FTHFA). The methodology employed used extraction with phosphate buffer, clean up with trichloroacetic acid and separation of the vitamins by high-performance liquid chromatography, with simultaneous ultraviolet and fluorescence detection. The results obtained for total folate were 551 to 1404 µg.100 g -1 for the button...

Crescimento micelial in vitro de cinco linhagens de Agaricus bisporus submetidas a diferentes condições de temperatura - DOI: 10.4025/actasciagron.v32i1.333 Agronomy
Andrade, Meire Cristina Nogueira de; INPA; Chavari, João Lucas; UNESP; Minhoni, Marli Teixeira de Almeida; UNESP; Zied, Diego Cunha; UNESP.
Avaliou-se o crescimento micelial in vitro das linhagens ABI-05/03, ABI-06/04, ABI-04/02, ABI-06/05 e ABI-01/01 de Agaricus bisporus em meios de cultura sólidos à base de composto. As avaliações foram realizadas por meio de medições de quatro diâmetros das colônias, a cada 48h, durante 12 dias de incubação, no escuro, a 20 e 25ºC. O delineamento experimental foi o de blocos casualizados, com uso do teste de Tukey para a comparação das médias. Com base nos resultados obtidos, verificou-se que: o crescimento micelial de A. bisporus é influenciado pela temperatura de incubação; a temperatura de 25ºC foi mais favorável para o crescimento micelial de todas as linhagens de A. bisporus; na temperatura de 20ºC, o melhor crescimento foi...

CULTIVATION OF THE EDIBLE MUSHROOM OUDEMANSIELLA CANARII (JUNGH.) HÖHN. IN LIGNOCELLULOSIC SUBSTRATES BJM
Ruegger,Marcelo José Silveira; Tornisielo,Sâmia Maria Tauk; Bononi,Vera Lúcia Ramos; Capelari,Marina.
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...

EVALUATION OF THE VIABILITY OF PLEUROTUS SPP. STRAINS AFTER LIQUID NITROGEN CRYOPRESERVATION Rev. Microbiol.
Lara-Herrera,Isabel; Mata,Gerardo; Gaitán-Hernández,Rigoberto.
Viability of 6 mushroom strains of the Pleurotus genus (2 from P. djamor var. djamor, 1 from P. ostreatus var. ostreatus, 2 from P. ostreatus var. columbinus and 1 from P. pulmonarius) after liquid nitrogen cryopreservation (-196º) was evaluated. The contact time for the mycelia of these strains with the cryoprotectant (glycerol) was studied 1, 2 and 3 hours before freezing. We also tested the effect of different times (5, 10 and 15 minutes) and temperatures (30, 45 and 60ºC) of the thawing system for mycelial recovery. The results showed a marked tendency toward faster mycelial recovery when samples were thawed at 30ºC, while at 60ºC no recovery was observed. A change in thawing and contact times with the cryoprotectant did not affect the results...

Genetic characterization of isolates of the basidiomycete Agaricus blazei by RAPD BJM
Colauto,Nelson Barros; Dias,Eustáquio Souza; Gimenes,Marcos Aparecido; Eira,Augusto Ferreira da.
The genetic divergence of five isolates of Agaricus blazei was determined based on RAPD data. Results indicate that there is little genetic variability among the commercialized strains and that RAPD is a feasible and low cost technique that can be used to characterize this fungus.

Growth and antibacterial activity of Lentinula edodes in liquid media supplemented with agricultural wastes Electron. J. Biotechnol.
Hiroko Hassegawa,Regina; Megumi Kasuya,Maria Catarina; Dantas Vanetti,Maria Cristina.
Antibacterial activity of Lentinula edodes against Bacillus subtilis was evaluated in cell-free filtrates obtained after growth in 14 different culture media. The highest B. subtilis growth inhibition was promoted by filtrates of growth media supplemented with rice bran, vermiculite or molasses. L. edodes dry mycelial biomass in liquid culture with 0.5% added rice bran was 3.2 mg/ml, after growth for 30 days at 25ºC without shaking, and 4.3 mg/ml under orbital shaking (150 rpm). However, antibacterial activity, detected between 20 and 24 days of incubation of stationary cultures, was absent in filtrates of aerated cultures. Temperatures of 20-25ºC enhanced both growth and antibacterial activity. Optimum pH for L. edodes mycelial growth...

Taxonomic studies of Amanita muscaria (L.) Lam (Amanitaceae, Agaricomycetes) and its infraspecific taxa in Brazil Acta Botanica
Wartchow,Felipe; Maia,Leonor Costa; Cavalcanti,Maria Auxiliadora de Queiroz.
We analyzed specimens identified as Amanita muscaria, some recently collected and others already deposited in herbaria, in Brazil. We concluded that two subspecies of A. muscaria occur in Brazil: A. muscaria var. muscaria; and A.muscaria var. flavivolvata. The first taxon was found in association with Castanea sativa, and the second (one specimen only) was found in association with Pinus and Eucalyptus spp. Morphologically, A. muscaria var. flavivolvata is distinguished by a shallower subhymenium and by basidiospores that are more elongated than are those of A. muscaria var. muscaria, which is the more widely known subspecies. We present descriptions, discussions, illustrations and a dichotomous key for these two subspecies.

The effects of a combination of garlic, oyster mushroom and propolis extract in comparison to antibiotic on growth performance, some blood parameters and nutrients digestibility of male broilers Rev. Bras. Ciênc. Avic.
Daneshmand,A; Sadeghi,GH; Karimi,A.
A study was conducted to evaluate the combined effects of garlic, oyster mushroom and propolis extract on the growth performance, organ weights, antibody response to Newcastle Disease Virus (NDV), serum lipid concentrations and nutrient digestibility of male broilers. A total of 192 day old chicks (Ross 308) were randomly assigned to 3 treatments with 4 replications (16 birds per replication). Experimental treatments were a maize- soybean based diet as control, control diet supplemented with a combination of garlic (30 g/kg), oyster mushroom (2 g/kg) and propolis extract (0.2 g/kg) known as GMP, and control diet supplemented with Virginamycin (0.25 g/kg) as antibiotic. The inclusion of GMP decreased (p < 0.05) live body weight, average daily gain and...
