Fungus for producing quorum effect inhibitor

The invention is applicable to the technical field of microorganism development and utilization, and provides a fungus for producing a population effect inhibitor and application thereof, the fungus is JW-13-1, and the preservation number of the fungus is CGMCC No.41110. The fungus is applied to production of penicillic acid. The yield of the penicillic acid produced by the provided fungus is that 0.1 g of penicillic acid is produced by fermentation per 1 L, the purity of the penicillic acid is 99.5% or above, the yield of the penicillic acid produced by the fungus is improved by 100-200% compared with the conventional microbial fungus for producing the penicillic acid, and when the fungus is applied to the production of the penicillic acid, the yield of the penicillic acid can be effectively improved, and the production efficiency of the penicillic acid can be improved. 本发明适用于微生物开发利用技术领域，提供了一种产群体效应抑制剂的真菌及其应用，所述真菌为JW-13-1，其保藏编号为CGMCC No.41110。并将所述真菌应用于生产青霉酸中。所提供的真菌产青霉酸的产量为每1 L发酵生产得到0.1 g青霉酸，并且青霉酸的纯度在99.5％以上，较
