Isolation and antifungal screening of endophytic fungi from Erigeron canadensis

Abstract

<p class="Abstract">Sixteen fungal strains isolated from the Erigeron canadensis, one of traditional Chinese medicines used to treat the pathogenic infection and dysentery, were evaluated for their antifungal activities against one human pathogen Candida albicans, and two phytopathogens, Colletotrichum fructicola and Rhizoctonia cerealis. The bioassay results indicated that the ethyl acetate extract of the fermentation broth of these fungal endophytes had stronger antimicrobial activities. Among these endophytic strains, the ethyl acetate extracts of strains NPR003 and NPR005 showed the strongest inhibitory effects and has potential application in the discovery of new antifungal agents. This was the first report on the isolation of endophytic fungi from E. canadensis and evaluation of their antifungal activities.</p><p class="Abstract"><strong>Video Clip of Methodology</strong>:</p><p class="Abstract">1 min 4 sec <a href="https://www.youtube.com/v/EdohQU3anR4">Full Screen</a> <a href="https://www.youtube.com/watch?v=EdohQU3anR4">Alternate</a></p>

Antimicrobial activity of secondary metabolites produced by Aspergillus neobridgeri isolated from Pistacia lentiscus against multi-drug resistant bacteria

“…Among 16 fungal strains isolated from the Erigeron canadensis, the ethyl acetate extract of strains NPR003 and NPR005 showed the strongest antifungal inhibitory effects (Bai et al, 2017). Bai et al (2019) isolated six endophytic fungal strains from Rumexmadaio, strains L1 and R1 belonged to the Colletotrichum and Fusarium genera respectively had stronger inhibitory effects on Staphylococcus aureus, and the R1 isolate was the source of two known antimicrobial agents dibutylphthalate and beauvericin.…”
