We evaluated the biomass and ergosterol content of Hericium erinaceus mycelium, and extracellular enzyme activities in H. erinaceus liquid culture following salicylic acid (SA) and methyl jasmonic acid (MeJA) supplementation. The optimal SA concentration was 100 µmol·L−1, where the highest ergosterol content of 2.33 mg·g−1 was obtained following 6-day cultivation with 100 µmol·L−1 SA supplementation, and which was significantly higher than the unsupplemented control (p < 0.01). Following 4-day supplementation with 50 μmol·L−1 MeJA, the highest ergosterol content obtained was 1.988 mg·g−1, which was 25.8 % higher than the unsupplemented control. Our data indicate that SA and MeJA supplementation improves ergosterol content in H. erinaceus mycelium. © 2015, Northeast Forestry University and Springer-Verlag Berlin Heidelberg.
