چکیده :

The culture medium is one of the most important effective parameters in the biosynthesis and production of nutrient and bioactive compounds of mushrooms. Accordingly, by optimization the culture media, it is possible to production of mushrooms with higher contents of nutrient and bioactive compounds. In this study, the effect of optimizing the culture medium of edible-medicinal mushroom Pleurotus ostreatus on the contents of production of dry fruiting body biomass, dietary fibers, chitin, and polysaccharides (as the important bioactive compounds of edible-medicinal mushrooms) was evaluated. The results showed that by optimizing the edible mushroom culture medium with wheat bran and malt extract, the contents of biosynthesis and production of soluble (from 2.94 ± 020 to 4.08 ± 0.24 g/100g DW), insoluble (from 5.77 ± 0.19 to 7.61 ± 0.16 g/100g DW), and total (from 8.71 ± 0.40 to 11.70 ± 0.38 g/100g DW) dietary fibers, chitin (from 0.856 ± 0.09 to 1.276 ± 0.14 g/100g DW), and polysaccharides (from 19.30 ± 0.79 to 39.55 ± 1.35 g/100g DW) significantly increased. These findings show that it is possible to increase the amount of biosynthesis and production of bioactive compounds of the edible-medicinal mushroom P. ostreatus. Furthermore, it can be used as a valuable functional food ingredient or dietary supplement in the diets of patients.
