-The objective of this work was to evaluate yield and chemical composition of oyster mushroom strains newly introduced in Bangladesh. Strains of Pleurotus high-king (strain PHK), P. ostreatus (strain PO2), and P. geesteranus (strains PG1 and PG3) were evaluated as to yield components and proximate composition. Pleurotus ostreatus was used as control. Pleurotus high-king showed fastest growth of primordia, but moderate flush of effective fruiting bodies. Pleurotus geesteranus (PG1) showed higher economic yield and biological performance, and better chemical composition, especially in terms of protein and mineral contents. Pleurotus geesteranus (PG1) shows better performance than P. ostreatus (PO2), the most commercially cultivated edible species in Bangladesh, and, therefore, it should be recommended for commercial cultivation.Index terms: Pleurotus, fruiting body, mushroom cultivation, proximate composition, yield components. Produtividade e composição nutricional de linhagens de cogumelo-ostra recentemente lançadas em BangladeshResumo -O objetivo deste trabalho foi avaliar a produtividade e a composição química de linhagens de cogumelo-ostra introduzidas recentemente em Bangladesh. Linhagens de Pleurotus high-king (linhagem PHK), P. ostreatus (linhagem PO2) e P. geesteranus (linhagens PG1 e PG3) foram avaliadas quanto aos componentes da produção e à composição proximal. Pleurotus ostreatus foi utilizado como controle. Pleurotus high-king apresentou rápido crescimento de primórdios, mas fluxo moderado de corpos de frutificação efetivos. Pleurotus geesteranus (PG1) apresentou maior produtividade econômica e desempenho biológico, além de melhor composição química, especialmente em termos de conteúdos de proteína e minerais. Pleurotus geesteranus (PG1) apresenta melhor desempenho que P. ostreatus (linhagem PO2), a espécie comestível mais cultivada comercialmente em Bangladesh, e, portanto, deve ser recomendado para plantio comercial.Termos para indexação: Pleurotus, corpo de frutificação, cultivo de cogumelos, composição proximal, componentes de produção.

“…This activity is related to their capacity to act as reducing agents, scavenge free radicals, quench singlet oxygen, or chelate metal ions (Balasundram et al, 2006;Ferreira et al, 2009). Furthermore, several studies have shown that the presence of phenolic compounds in mushroom extracts correlated with antioxidant activity, which depended on the type of mushroom, stage of development, age of the fresh mushroom, storage conditions (Guillamón et al, 2010), or preparation procedures. For example, the methanolic extract and crude polysaccharides of log black fungi (L. polychrous) found in northern and northeastern Thailand exhibited antioxidant activity and an inhibitory effect on breast cancer cells (Armassa et al, 2009;Thetsrimuang et al, 2011a;2011b).…”

Several kinds of cultivated or local edible mushrooms exist in northern Thailand. While their nutritional features have been extensively analyzed, the presence of phytochemicals and glycosaminoglycans has yet to be investigated. Thus, in this study, we examined the presence of phytochemicals and glycosaminoglycans from 10 cultivated or local mushrooms: milk white russula, hygroscopic earthstar, log white fungi, log black fungi, shitake mushroom, rosy russula, sajor-caju mushroom, Jew's ear, bolete, and straw mushroom. Phytochemical analysis revealed the presence of carbohydrates, amino acids, and flavonoids in the extracts from most of the mushrooms. We detected glycosaminoglycans in all of the extracts using dimethylmethylene blue (DMMB) dye-binding assay and UVVis spectrophotometry. Hygroscopic earthstar contained the most glycosaminoglycans and sajor-caju mushroom the least. However, we were unable to distinguish the types of glycosaminoglycans, which should be considered for future study. In summary, the phytochemicals found here are crucial non-animal dietary sources of carbohydrates, amino acids, and antioxidants. In addition, the glycosaminoglycans detected in the mushroom extracts in this study potentially offer a non-animal source of glycosaminoglycans that may have clinical applications, apart from their nutritive value.

“…Thus the role of fruit body age and size is of less importance owing to the limited proportion of contaminants originating from atmospheric depositions. However, this role may increase in some wood-growing species that have a longer lifespan than is usual in aboveground species [16][17][18][23][24][25]28,29]. Mushrooms not only accumulate elements from underlying substrate but also from host trees depending on the specificity of species.…”

“…Elements detrimental to humans originate from both natural sources and anthropogenic activities. Motor transport delivers significant amounts of both gaseous pollutants and selected elements, which generally negatively influence human health and contribute to changes in climate (EPA) [23][24][25]32]. In Bulgaria, apart from the sale of cultivated mushrooms in shops, wild growing mushroom species are frequently sold along roadsides and in street markets.…”
