In this study, we have investigated the antibacterial, antioxidant, and antitumor activities on mycelium cultural extract from mushroom. Mushroom mycelium was grown in a synthetic liquidmedia as well citrus extracts. In antibacterial activity, the best result was achieved when mycelium cultural extract mixed the Phellinus linteus and Coriolus versicolorwas incubated on YM broth. Then again, mushroom mycelium on citrus extracts showed better activity than that
on PD broth. We have tested the antioxidant activity at concentration up to 10 mg/ml of mycelium cultural extract. The higher antioxidant activity was observed on PD broth containing the Phellinus linteus and Coriolus versicolor mycelium as well citrus extract containing Phellinus linteus and Coriolus versicolor mycelium. The complex culture extracts obtained from the synthetic medium and citrus extract medium showed 10～89% of the1,1-diphenyl-2-picrylhydrazyl radical scavenger activity. The antitumor activity of mycelium cultural extract was examined by using MTT assay on A549 cells. Mushroom mycelium on citrus extract showed interestingly higher antitumor activity than mushroom mycelium on synthetic liquid medium.
