ARTIFICIAL CULTIVATION OF Pycnoporus sanguineus ON ACACIA SAWDUST

Abstract

Forestry waste is a readily available and low - cost source of raw material for mushroom cultivation. Using Acacia sawdust as a substrate for medicinal mushrooms represents an important circular economy solution that enhances economic efficiency, reduces environmental pollution, creates employment, and supports sustainable forestry development. The Pycnoporus sanguineus showed good growth on PDA medium at 20 - 30 °C, with optimal development at 30 °C. Among the tested formulas, Formula 2 (89% acacia sawdust, 5% rice bran, 5% corn powder, and 1% CaCO₃) achieved the fastest mycelial colonization (25.7 days) and the highest yield, producing 120.16 g fresh weight, equivalent to 30.58 g dry weight after two harvests.
