Abstract
Lentinus tigrinus is an edible basidiomycetes fungus that is known to be nutritious and exhibit functional activities. With the intention of developing technique on the production of mycelial biomass, the effects of select cucurbit-based media on the mycelial performance and antioxidant properties of L. tigrinus were evaluated. Mycelial growth performance was evaluated in both solid and liquid culture conditions. The DPPH radical scavenging activity and the total phenolic content of the mycelia grown in the select cucurbit-based liquid media at the best concentration were analyzed. Mycelia on squash decoction gulaman recorded the widest mycelial diameter (71.99 mm) and shortest period of incubation (6.0 days), regardless of concentration. However, 500 g/L concentration of all cucurbit species registered the widest mycelial diameter with a mean of 73.35 mm. In liquid culture, the heaviest mycelial biomass was noted in both squash broth and luffa broth with a mean of 0.09 g, but the highest volume loss was recorded in squash broth (14.22 ml). Among concentrations, 500 g/L of all broth media had the highest mycelial biomass (0.14 g) and volume loss (13.42 ml). Mycelia grown in winter melon broth showed the highest radical-scavenging activity (51.56%) and total phenolic content (25.04 mg GAE/g sample).
