In
this study, the usage possibilities of some agro-industrial wastes such as;
peanut wastes, potatoes farm wastes, walnut and orange tree sawdust in Pleurotus ostreatus cultivation were
investigated and total phenolic, flavonoid, condensed tannin content and antioxidant properties of
these methanolic mushroom extracts were examined. For the determination of the
total phenolic contents, the Folin-Ciocalteau procedure was used. The content
of total flavonoid present in the methanolic extracts was measured using a
spectrophotometric assay. Condensed tannins were determined according to the
method by Julkunen-Tıtto. The antioxidant capacity was determined using ferric
reducing antioxidant power (FRAP) and free radical scavenging activity of DPPH.
The highest total phenolic content (2.672 ± 0.003 mg GAE/g) was found in
mushroom cultivated on walnut sawdust. The highest condensed tannin (1.011 ±
0.088 CE mg/g) and ferric reducing antioxidant power (FRAP) (12.332 ± 0.017
μmol FeSO4.7H2O/g) were observed in the same mushroom extract. The
highest total flavonoid and free radical scavenging activity of DPPH were found
in extract of mushroom cultivated on potatoes handle. Bioactive properties of P. ostreatus cultivated on walnut tree
sawdust were generally exhibited remarkable results.
