[ Method] Some low toxic and pollution- free chemical reagents were first selected to carry out indoor toxicity test, and their inhibition effects against myxomyeetes were measured. Then the reagents with small effect on the growth of Pleurotu.s ostreatua were selected according to the indoor bioassay results, and carried out control test against myxomyeetes disease in mushroom house. [ Results] The results showed that the combination of Ludanlan sephora flavescens 1 000 times liquid ＋ salicylic acid 300 times liquid, Clolrim- azole suppositories 1 000 times liquid, Ludanlan sophora flavescens 1 000 times liquid and salicylic acid 300 times liquid had the best control efficacy against the disease. They were the preferred reagents for the prevention of myxomycetes disease in production practice. [ Conclusion] The results provided basis for the effec- tive control d myxomycetes disease in edible fungi.展开更多

However, there are relatively few reports with insufficient data regarding the protein quality of these foods, especially of edible seeds and nuts from Brazil. The aim of this study was to investigate the chemical composition and in vivo protein quality of two edible seeds (baru almond and peanut) and two nuts (Brazil nut and cashew nut) grown in Brazil. The proximate composition and the amino acid profile were analyzed. The true protein digestibility and the protein quality of these foods were evaluated by bioassay with male weanling Wistar rats over a period of 14 days, and the Protein Digestibility Corrected Amino Acid Score (PDCAAS) was estimated. Edible seeds and nuts presented high contents of proteins (16.3 to 32.3 g/100g), lipids (42.7 to 57.9 g/100g) and dietary fibers (6.5 to 14.3 g/100g). Lysine was found to be the limiting amino acid in baru almond, peanut and Brazil nut, which had amino acid scores ranging from 71% to 76%. Cashew nut had no limiting amino acid. These foods showed high protein digestibility (around 90%) except for baru almond (75%), and their PDCAAS values varied significantly (57%, for baru almond, and 90%, for cashew nut). The edible seeds and nuts grown in Brazil provide a high density of energy and nutrients and they can be used as complementary sources of proteins.展开更多
