“…Annual production of these mushrooms is more than 900 000 tons. There are a lot of different species in the genus Pleurotus that have pharmacological properties, for example P. florida, P. tuber-regium, P. sajorcaju, P. pulmonarius, P. ostreatus, and P. eryngii (Ragunathan et al 1996). It has been reported earlier that the fruit bodies and sclerotia of these species contain specific glucans (Karácsonyi & Kuniak 1994;Cheung & Lee 1998;Chenghua et al 2000;Manzi & Pizzoferrato 2000;Rout et al 2005).…”

Synytsya A., Míčková K., Jablonský I., Sluková M., Čopíková J. (2008): Mushrooms of genus Pleurotus as a source of dietary fibres and glucans for food supplements. Czech J. Food Sci., 26: 441-446.Fruit bodies (separately pilei and stems) of mushrooms Pleurotus ostreatus (four strains) and Pleurotus eryngii were characterised as a source of polysaccharides. The contents of glucans and dietary fibres were determined with using the respective Megazyme enzymatic kits. Enzymatic analysis of the fruit bodies confirmed significant differences in the contents of these components among the species and strains. The stems contained more insoluble dietary fibres than the pilei in all the cases and more β-glucans in most cases. However, relatively high contents of β-glucan (20-50% of dry matter) could be a result of incomplete enzymatic hydrolysis of insoluble α-1,3-glucans. Nevertheless, low food quality stems of mushrooms Pleurotus sp. could be a valuable source of cell wall glucans for the preparation of food supplements.Keywords: mushrooms Pleurotus; glucans; dietary fibres; food supplements For millennia, humankind has been valued mushrooms as an important edible and medical resource (Chang 1980;Breene 1990;Wasser 2002). The dry matter of mushroom fruit bodies is about 5-15%, they have a very low fat content and contain 19-35% proteins. Mushroom fruit bodies are rich in vitamins, mainly B 1 , B 2 , C, and D 2 (Manzi et al. 1999;Mattila et al. 2000), and contain some important elements such as K and P (Vetter 2007). The content of carbohydrates, which are mainly present as polysaccharides or glycoproteins, ranges 50-90%; the most abundant polysaccharides are chitin, α-and β-glucans and other hemicelluloses (e.g. mannans, xylans and galactans). 442Vol. 26, No. 6: 441-446 Czech J. Food Sci. 1988). Their solubility in water strongly depends on the molecular structure and conformation. Glucans bound to proteins or to chitin are usually insoluble in water. Mushroom-derived substances with antitumour, immunomodulating, and antioxidative properties are currently used as dietary supplements. Mushroom polysaccharides with antitumour action differ greatly in their chemical compositions and configurations, as well as in their physical properties. Immunomodulatory and antitumour activities are exhibited by a wide range of glycans extending from homopolymers to highly complex heteropolymers; the differences in their activities can be correlated with the solubility in water,molecular size, branching rate and form (Augustín 1998; Ooi & Lui 1999;Wasser 2002;Novak & Vetvicka 2008). Besides the well-known antitumour β-(1→3),(1→6)-glucans (Kuniak et al. 1992(Kuniak et al. , 1998, a wide range of biologically active glucans of different structures have been described. Linear or branched polysaccharides chains occur with a backbone composed of α-or β-linked glucose units, and their various side chains can be attached in different ways. The main source of biologically active polysaccharides appears to be fungal cell walls consisti...

“…Finalmente, para a cultivar PrataAnã, o meio suplementado com farelo de arroz apresentou uma tendência de maiores valores de crescimento fúngico que as demais, ao longo do período de incubação. Maziero et al (1990) e Ragunathan et al (1996) também citaram que a velocidade de crescimento e o vigor são parâmetros que podem ser influenciados pela composição do substrato, pelos isolados testados e pela suplementação fornecida. Nyochembeng et al (2008), avaliando o crescimento micelial de L. edodes em resíduos da colheita de tomate, feijão-soja, feijão-caupi, manjericão, batata doce e palhas de arroz e de trigo, observaram que os substratos à base de palhas apresentaram médias significativamente maiores em relação as demais formulações utilizadas.…”
