Volatile Metabolome and Transcriptomic Analysis of Kosakonia cowanii Ch1 During Competitive Interaction with Sclerotium rolfsii Reveals New Biocontrol Insights

mycolabadmin

Researchers studied how a beneficial bacterium called K. cowanii fights against a harmful soil fungus (S. rolfsii) that damages crops like chili peppers. The bacterium produces special smelly compounds (VOCs) that kill the fungus. When these compounds are present, the bacterium activates specific genes that help it produce substances to protect itself and inhibit fungal growth. This research could help farmers use natural biocontrol instead of chemical fungicides.

Improvement of antioxidant capacity, aroma quality, and antifungal ability of cherry by phenyllactic acid treatment during low temperature storage

mycolabadmin

Researchers found that treating sweet cherries with phenyllactic acid (PLA), a natural organic acid, can significantly extend their shelf life while keeping them fresh and flavorful. A treatment with 8 mmol·L⁻¹ PLA concentration worked best, reducing decay, maintaining firmness and sweetness, and improving the fruit’s natural antioxidant properties during cold storage. This natural preservative approach offers a safe alternative to chemical fungicides while preserving the delicious taste and nutritional quality that consumers value in cherries.

Reduction of Beany Flavor and Improvement of Nutritional Quality in Fermented Pea Milk: Based on Novel Bifidobacterium animalis subsp. lactis 80

mycolabadmin

Researchers used a beneficial bacteria strain (Bifidobacterium animalis subsp. lactis 80) to ferment pea milk, reducing the unpleasant ‘beany’ taste that limits pea milk popularity. Fermentation broke down flavor compounds responsible for grassy and fatty odors while creating new fruity and floral aromas. The process also improved the milk’s texture and consistency while maintaining nutritional benefits, making pea-based beverages more appealing to consumers.
