AI Technical Summary
The presence of coumarin in sweet clover can cause poisoning in ruminants, and current technologies are unable to effectively degrade it, affecting its application as a high-quality forage.
Osmanthus fragrans was pretreated with fermentation broth of *Eriocaulon buergerianum* LGM-ZA13 to degrade coumarin using its secreted acetylylanase. The fermentation conditions were anaerobic fermentation for 72-196 h at 39℃. The fermentation broth contained basal culture medium, trace element buffer, cell-free rumen fluid, and redox agents.
It significantly improved the degradation rate of coumarin in sweet clover, from 47.2% to 80.7%, providing a safety guarantee for the application of sweet clover as forage and alleviating the current shortage of high-quality forage resources.
