A zinc (Zn)-tolerant fungus, designated BC109-2, was isolated from rhizosphere soil and was identified as Penicillium janthinellum BC109-2 based on ITS sequence analysis. To understand its Zn tolerance mechanisms, a series of studies was carried out addressing the subcellular distribution of Zn, its chemical forms, and the antioxidant system (superoxide dismutase, catalase, peroxidase, glutathione reductase, glutathione S-transferase, reduced glutathione, oxidized glutathione and malondialdehyde) of the fungus. The maximum level of resistance to Zn for strain BC109-2 is 2100 mg L(-1). Read More
