Exploring yeast-based microbial interactions: The next frontier in postharvest biocontrol

Area of Science:

• Agricultural Science
• Microbiology
• Food Science

Background:

• Fresh produce faces significant postharvest losses due to microbial spoilage, primarily from fungi.
• Synthetic fungicides are widely used but raise concerns regarding resistance and consumer health.
• There is a growing demand for safer, environmentally friendly, and cost-effective biocontrol alternatives.

Purpose of the Study:

• To review the potential of antagonistic yeasts as biocontrol agents for postharvest fruit and vegetable spoilage.
• To explore yeast-based interactions (yeast-mold, yeast-bacteria, yeast-yeast) and their mechanisms of action.
• To discuss the advantages, efficiency improvements, commercialization, and future prospects of yeast biocontrol.

Main Methods:

• Literature review focusing on yeast-based biocontrol strategies for postharvest disease management.
• Analysis of yeast-mold, yeast-bacteria, and yeast-yeast interactions in the context of fruit and vegetable preservation.
• Examination of mechanisms underlying yeast antagonism and efficacy in biocontrol systems.

Main Results:

• Yeast-based biocontrol is a promising strategy, with several products already commercialized.
• Existing research predominantly focuses on yeast-mold interactions, neglecting other microbial dynamics.
• Understanding diverse yeast interactions is crucial for optimizing biocontrol efficacy and broadening applications.

Conclusions:

• Antagonistic yeasts provide a viable, sustainable alternative to synthetic fungicides for reducing postharvest losses.
• Further research into yeast-bacteria and yeast-yeast interactions is essential for enhancing biocontrol strategies.
• Optimizing antagonist efficiency and addressing commercialization challenges will facilitate wider adoption of yeast biocontrol.
