<i>Hericium erinaceus</i> Basidiomas Chemical Composition and Antioxidant Properties Depending on the Pretreatment of Pine and Beech Sawdust
The effect of pretreatment of lignocellulosic substrates on the fruit bodies forming of a xylotrophic basidiomycete Hericium erinaceus (Bull.) Persoon was studied, as well as the antioxidant properties of fruit body extracts. Pretreatment of beech and pine sawdust with mineral acids increased the bioavailability of the substrate for H. erinaceus and led to a significant reduction in the time required to form fruit bodies from 63 to 35 days as compared to untreated sawdust. All variants of substrates with pine sawdust ensured the production of fruit bodies with an increased content of phenolic compounds in comparison with substrates containing beech sawdust. Pretreatment with sulfuric acid led to an increase in the antiradical activity and chelating ability of fruit body extracts.
