AI Technical Summary

Technical Problem

There is a lack of safe and efficient method for adsorbing and removing zearalenone (ZEN) in the prior art. There is a risk of secondary contamination by chemical methods, physical methods cannot be completely removed, and biological enzyme conversion has the limitations of being inresistant to acid and alkali and producing stronger toxic substances.

Method used

Bacillus licheniformis YJ25 and its bacterial agent are used to adsorb ZEN by adsorbing peptidoglycan and phosphoacid molecules on its cell walls, achieving rapid and efficient adsorption and removal.

Benefits of technology

The adsorption rate of Bacillus lichenid YJ25 to ZEN reaches 100% within 2 hours, which is safe and feasible, providing a solid foundation for detoxification in food and feed.
