Fungal Pathogens and Toxins Related to Food Safety

Current research and/or projects

The current research is in the field of food safety and focuses on exploring and investigating cost-efficient green technologies to mitigate fungal hazards and mycotoxin contaminations in human food and animal feed. His research team has discovered beneficial bacterial strains that possess outstanding capabilities to detoxify mycotoxins, such as vomitoxin (DON) and patulin, and to diminish their bio-toxicity. State-of-the-art methods are being developed nowadays in his laboratory to pan out the mechanisms/bacterial enzymes responsible for mycotoxin detoxifications. Dr. Zhou keeps taking a leading role in mycotoxin research and his innovative biodetoxification technology has led to fruitful collaborations with food and feed processing industries and is being developed for commercial applications in deterring or eliminating risks associated with mold growth/mycotoxin presence in agricultural commodities.

Research and/or project statements

  • Mitigation of Fusarium mycotoxins in food production chain by biodetoxificati​on
  • Control of the mycotoxin patulin in food through biodetoxification
  • Toxicity assessments of novel bacterial metabolites of mycotoxin zearalenone and the bacteria presenting the metabolism
  • The application of the deoxynivalenol bioconversion system to detoxify the mycotoxin in grains and DDGs
  • Characterization and enhanced release of bioactives in pulse/grain processing by-products for novel functional food ingredients with greater bioavailability and health benefits

Professional activities / interests

  • Development of microbial and enzymatic detoxifications for mitigation of fungal toxins (mycotoxins) in food and feed
  • Detection and control of mycotoxins with biological, physical and chemical approaches during storage and processing
  • Occurrence and control of toxin producing fungi in fruit and grains with biological agents and natural antimicrobials
