Abstract

Background: Microbial exopolysaccharides represent a significant source of polysaccharides, with their production unconstrained by temporal or spatial limitations. Penicillium, a filamentous fungus widely recognized for its medicinal food applications, is known to produce exopolysaccharides that exhibit cancer-inhibitory properties.

Results: In the present study, exopolysaccharides from Penicillium EF-2 (EPS) were extracted and structurally characterized using ion chromatograph, infrared spectroscopy and NMR. The in vitro antioxidant and immunomodulatory activities were also investigated. EPS has a molecular weight of 111.47 kDa, is primarily composed of mannose, glucose and galactose, possesses a crystalline region, and exhibits excellent thermal properties. In free radical scavenging assays, EPS demonstrated robust in vitro antioxidant activity. Furthermore, EPS activated the mitogen-activated protein kinase pathway, enhancing the immunomodulatory capacity of macrophages.

Conclusion: EPS has excellent antioxidant and biological activities. The present study provides a theoretical basis for the utilization of EPS and offers new ideas for active sources of Penicillium fermented foods. © 2025 Society of Chemical Industry.

期刊介绍： The Journal of the Science of Food and Agriculture publishes peer-reviewed original research, reviews, mini-reviews, perspectives and spotlights in these areas, with particular emphasis on interdisciplinary studies at the agriculture/ food interface. Published for SCI by John Wiley & Sons Ltd. SCI (Society of Chemical Industry) is a unique international forum where science meets business on independent, impartial ground. Anyone can join and current Members include consumers, business people, environmentalists, industrialists, farmers, and researchers. The Society offers a chance to share information between sectors as diverse as food and agriculture, pharmaceuticals, biotechnology, materials, chemicals, environmental science and safety. As well as organising educational events, SCI awards a number of prestigious honours and scholarships each year, publishes peer-reviewed journals, and provides Members with news from their sectors in the respected magazine, Chemistry & Industry . Originally established in London in 1881 and in New York in 1894, SCI is a registered charity with Members in over 70 countries.
