 This study discovered a new strain of bacteria, ketogelonisogenium vulgar, which can break down the mycotoxin deoxynivalenol, dawn. This strain is able to degrade dawn at low concentrations, even when grown under different environmental conditions. Furthermore, it produces a less toxic metabolite called 3-ketodon, which is more effective at killing plant cells than dawn itself. These findings suggest that this strain may be used to develop novel strategies for detoxification of dawn in food and animal feed.
