Induction and Quantification of Patulin Production in Penicillium Species
Authors:  Yong Chen, Boqiang Li, Zhanquan Zhang and Shiping Tian, date: 06/05/2017, view: 7822, Q&A: 0
Patulin, a worldwide regulated mycotoxin, is primarily produced by Penicillium and Aspergillus species during fruit spoilage. Patulin contamination is a great concern with regard to human health because exposure of the mycotoxin can result in severe acute and chronic toxicity, including neurotoxic, mutagenic, and immunotoxic effects. Penicillium expansum is known as the main producer of patulin. This protocol addresses the cultivation procedure of P. expansum under patulin permissive conditions and describes the method of collection and detection of patulin.
Pathogenicity Assay of Penicillium expansum on Apple Fruits
Authors:  Yong Chen, Boqiang Li, Zhanquan Zhang and Shiping Tian, date: 05/05/2017, view: 9747, Q&A: 0
Penicillium expansum, a widespread filamentous fungus, is a major causative agent of fruit decay and leads to huge economic losses during postharvest storage and shipping. Furthermore, it produces mycotoxin on the infected fruits that may cause harmful effects to human health. This pathogenicity assay involves a stab inoculation procedure of P. expansum on apple fruit, an important experimental technique to study fungal pathogenesis. This assay can be applied to analyze the virulence of postharvest pathogen on other fruits such as orange, pear and kiwifruit.
