Název v původním jazyce

Characterisation of beta-glucans isolated from Pleurotus sp.

Popis výsledku v původním jazyce

Pleurotus sp. is interesting as medicinal mushroom due to the significant content of beta-glucans. These polysaccharides are supposed to be responsible for some healthy properties of various mushrooms. There is evidence to study how beta-glucan distribution in fruit body depends on genetic differences between strains of Pleurotus sp., cultivation conditions and harvest term. The aim of this study was characterisation of beta-glucans and chitin-glucan complexes of four strains of Pleurotus sp. The contents of beta-glucans were determined separately in pilei and stems by Megazyme (Ireland) enzymatic kit contained exo-1,3-&#61538;-glucanase and &#61538;-glucosidase. Soluble and insoluble glucans were isolated according to the modified procedure of Chenghua et al. (2000). Lyophilised samples obtained from dialysed extracts, as well as insoluble residues, were analyzed by spectroscopic and separation methods. Enzymatic analysis confirms significant differences in beta-glucan contents among
