Abstract:
Ningxia is the main planting area of Lycium barbarum. Due to improper storage conditions, L. barbarum is very prone to mildew. It has caused significant economic losses. This study mainly analyzed the main fungal species causing mold and mildew of L. barbarum in Ningxia, and discussed the relevant consequences. The fungal strains were isolated from the mildewed fruits of L. barbarum collected from five villages in Ningxia. The strains were identified based on biobarcode technology and phylogenetic analysis was performed. The 45 isolated strains were identified as 10 genus, including: Alternaria spp.、Fusarium spp.、Rhizoctonia solani、Trichoderma longibrachiatum、Filobasidium magnum、Penicillium chrysogenum、Curvularia spicifera、Mucor fragilis、Aspergillus niger、Rhodotorula mucilaginosa. At least four fungi might produce mycotoxins, causing food safety problems. Therefore, the relevant laws and regulations should be revised to manage the quality of L. barbarum.
