• DPPH free-radical scavenging
• ferrous ion chelating ability
• reducing power
• total antioxidant activity
• total phenols
• Penicillium

The aim of this study was to investigate the biological and chemical activity of the two fungi species, genus Penicillium, isolated from wastewater. For the selected species of fungi, different antioxidant activity assays were used: DPPH free-radical scavenging activity, total antioxidant activity, Fe2+-chelating ability and Fe3+-reducing power. Total phenolic content was also determined for ethanolic extract of mycelia. Penicillium chrysogenum ethanolic extract contained higher total phenolic content and better total antioxidant capacity as well as ferrous ion chelating ability. Penicillium fumiculosum ethanolic extract showed higher DPPH free-radical scavenging activity, as well as reducing power. Based on the obtained results it can be concluded that two types of fungi are potential new sources of natural antioxidants.
