Isolation of Endophytic Fungi from Erigeron Acer L.andAntimicrobial Activities
摘要
Abstract
Investigation on biodiversity of endophytic microbes associated with Erigeron acer L.is carried out in this work.Using the method of plate separation, a total of 34 fungal strains are isolated from the organs of E.acer L., which twelve endophytic strains are from root, six strains from stem, and sixteen strains from leaf.Aspergillus and Penicillium are the predominant fungi in Erigeron acer L., Erigeron acer L.roots, stems and leaves have common genera——Penicillium.Using Oxford cup method, its antibacterial activity is measured, and the inhibition of 34 strains of fungi on Staphylococcus aureus, Moniliaalbican, lternariaalternata, Pseudomonas putida and Escherichia coli is investigated.The results show that the G5, J2, J4 strains with the strongest inhibition are Penicillium purpurogenum, Coprinus radians, Nomuraea rileyi.This study shows that Erigeron acer L.endophytic fungi has abundant diversity, and has strong antibacterial activity against pathogenic bacteria.关键词
