| مستخلص: | Postharvest loss is a major constraint in the production of grapes, both in terms of quality and quantity. In this study, 33 yeasts were isolated from the fructosphere of grapes and tested for their antifungal activity against Aspergillusspp., which infects grapes during the postharvest stage. The results revealed that the yeast isolate YBB3 exhibited maximum inhibitory effect against Aspergillusspp. in dual plate assay (57% over control). Molecular characterization of YBB3 showed 99.31% identity with Hanseniaspora guilliermondii. Wound site colonization of H. guilliermondiiin grape cv. Thompson Seedless showed 80% inhibition of Aspergillusspp. over the control in vitro. YBB3 produced volatile, non-volatile and thermostable compounds, which inhibited the mycelial growth of Aspergillusspp. In addition, YBB3 produced killer toxins, which were identified by the presence of blue colour-stained cells. Moreover, glycerol-based liquid bioformulations of H. guilliermondii(YBB3) showed maximum inhibitory effect against Aspergillusspp. (96%) over the control on inoculated wounded grapes berries. Thus, the yeast isolate H. guilliermondiiidentified and characterized in this study is worthy of further studies for the sustainable management of Aspergillus rot in grapes. |
