Antifungal activity of chitosan and its combination with the yeast Debaryomyces hansenii F9D for the control of Penicillium expansum in apples and pears stored at low temperatures

Bioprotective yeasts: Potential to limit postharvest spoilage and to extend shelf life or improve microbial safety of processed foods

“…Within these, certain strains are identified as “killer strains” due to their toxin-producing capacity. Debaryomyces has exhibited efficacy in mitigating postharvest diseases in horticultural crops, such as apple and pear [ 54 , 97 ], muskmelon [ 98 ], jujube [ 99 ], persian lime [ 52 ], kiwifruit [ 100 ], mango [ 53 ], etc. Among antagonistic yeasts, D. hansenii exhibits remarkable resilience in withstanding severe environmental stressors, encompassing low pH levels, suboptimal temperatures, and heightened osmotic pressures [ 101 ].…”
