Evaluation of Rhodosporidium fluviale as biocontrol agent against Botrytis cinerea on apple fruit

Abstract

Significance and Impact of the Study: Botrytis cinerea Pers: Fr, which causes gray mold of fruits and vegetables around the world, is difficult to control successfully because it is genetically variable and rapidly develops resistance to the chemicals commonly used for its control. This study is a contribution to the biocontrol of this phytopathogen fungus. The evaluation of the native yeast Rhodosporidium fluviale as biocontrol agent and the elucidation of possible mechanisms of action, including the participation of nonviable cells of this yeast, have not been reported up to date.

Fungal Endophytic Communities of Two Wild Rosa Varieties With Different Powdery Mildew Susceptibilities

“…were highly effective biological control agents of PM on flowering dogwoods ( Cornus florida L.). Sansone et al (2018) have demonstrated that Rhodosporidiobolus fluvialis could be used as a biocontrol agent against Botrytis cinerea . Therefore, higher endophytic colonization of Rhodosporidium spp.…”

Molecular Basis of Yeasts Antimicrobial Activity—Developing Innovative Strategies for Biomedicine and Biocontrol

“…Another red yeast, R. paludigenum, isolated from a marine environment, showed important antifungal activity based on nutrient competition against A. alternata tested both using in vitro and in vivo on cherry tomato, frequently affected by postharvest black rot disease [129]. In the case of R. fluviale, the main mechanism of antifungal activity against B. cinerea, which colonize apple fruit, is based both on the competition for the space and the induction of the β-1,3-glucanase production in apple tissue [130]. A study conducted by Huang et al [131] proved that N-acetylglucosamine exposure of R. paludigenum enhances its antifungal activity against P. expansum when tested directly on pears.…”

Recent Insights into the Use of Antagonistic Yeasts for Sustainable Biomanagement of Postharvest Pathogenic and Mycotoxigenic Fungi in Fruits with Their Prevention Strategies against Mycotoxins

“…In a recent study by Sansone et al, preventive and curative effects of yeast culture on apples were investigated. By the preventive effect, Rhodosporidium fluviale severity was reduced to 55% and 75% at the 5 th and 10 th days of storage with antagonistic yeasts, respectively.…”

“…111 The antifungal activity of the VOCs of W. anomalus, M. pulcherrima, and S. cerevisiae has been observed in in vitro and in vivo studies on grapes against B. cinerea. 112 In a recent study by Sansone et al, 113 preventive and curative effects of yeast culture on apples were investigated. By the preventive effect, Rhodosporidium f luviale severity was reduced to 55% and 75% at the 5 th and 10 th days of storage with antagonistic yeasts, respectively.…”
