Trehalose improves cold tolerance of Pediococcus pentosaceus OL77 and enhances low-temperature oat silage fermentation.

Key Points

• This research aims to determine how trehalose affects the cold tolerance and fermentation efficiency of Pediococcus pentosaceus OL77 in oat silage.
• Evaluated the impact of trehalose on OL77 strains during low-temperature fermentation.
• Conducted fermentation assays and measured silage quality indicators.
• Analyzed cold tolerance of OL77 in controlled environments.
• Trehalose-treated OL77 exhibited significantly improved fermentation rates at low temperatures.
• Silage quality indicators showed enhanced outcomes in trehalose-treated samples compared to controls.
• Cold tolerance metrics demonstrated that trehalose enhances resilience against suboptimal temperatures.
