Biosensors for detection of biological and chemical contaminants in agriculture, food and environment
An immuno-electrochemical biosensor was developed using immuno-magnetic beads for separation of SalmonellaTyphimurium and E. coli O157:H7 in food samples and enzymatic reaction for generation of electrochemical signals measured through a bienzyme (tyrosinase–horseradish peroxidase) electrode in a flow-injection analysis system. Then, a capillary column-based bioseparator/bioreactor was investigated for an optical immunosensor. Both electrochemical and optical biosensors could quantitatively detect S. Typhimurium and E. coli O157:H7 in a range of 101-107 cfu/ml in 1.5 h. A microfluidics-based chemiluminescent fiber optical biosensor was developed for detection of S. Typhimurium and Listeria monocytogenes and the results showed the pathogens could be detected at 100 cfu/ml within 1 h. A PCR-based biosensing method was studied to detect S. Typhimurium, L. monocytogenes and Campylobacter jejuni in food samples, by which as low as 2 cells/ml of target bacteria could be detected within 3 h. Interdigitated array microelectrode and magnetic micro/nanobeads based impedance biosensor was developed for detection of foodborne pathogens, and this method could detect 101-108 cells/ml in less than 1.5 h. QCM, SPR and Quantum Dots based biosensors were also studied for comparison. The results indicated that these biosensors are rapid, specific and sensitive, simple, portable and inexpensive in detection of pathogens in food, environmental and clinical samples. Microelectrodes, microfluidics, magnetic nanoparticles and nanotubes/nanowires are currently being studied for their applications in biosensors. Immuno-capillary based optical biosensors are being developed for rapid screening of two proteins linked to feed efficiency of breeder chickens and pesticide residues in vegetables and fruits.
Very recently, a microfluidics-based impedance biosensor in couple with magnetic nanoparticle-antibody conjugates for immunoseparation has been developed for in-field screening of avian influenza H5N1 virus. This portable, inexpensive biosensor is able to detect as low as 102 EID50/ml in 30 min. This research is also one of the projects supported by the USDA-MOST International Collaboration Program.
The biosensor research was supported by USDA/NRI, USDA/FAS, USDA/ARS, NSF, NAFSS, ASTA, ABI and the Food Safety Consortium. The biosensor research has resulted in five US patents pending that are licensed by BioDetection Instruments, LLC for technology transfer with two NSF/SBIR NIH/SBIR phase II projects and one NSF/STTR phase I project.
Modeling and simulation for microbial prediction and quantitative risk assessment in food and agriculture
The predictive microbial models including the first and second generation models were developed for survival/growth/death and cross-contamination of S. Typhimurium, C. jejuni and L. monocytogenes during food processing based on the data of both laboratory-scale and pilot-plant-scale experiments conducted for hatchery, scalding, chilling, cooking and refrigerating. A quantitative risk assessment model was developed based on Monte Carlo simulation using @Risk software for S. Typhimurium, C. jejuni and L. monocytogenes in poultry production and processing systems. The microbial kinetic models were integrated with the risk assessment model to predict the performance of foodborne pathogens in poultry. The simulation results provided the probability and consequence of microbial hazards associated with poultry products, including possible contamination of S. Typhimurium and L. monocytogenes. Sensitivity analysis presented the relationship between the risk and operation parameters or critical control points.
The research on microbial risk assessment models was funded by USDA/CSREES, USDA/NRI, USDA/ARS, NAFSS and the Food Safety Consortium. A website was built and an invention disclosure is filed.
Antimicrobial technologies and equipment for food processing and food safety
An electrical pasteurization system was designed and constructed for treatment of chilling brine used in food processing. Pilot-plant-scale tests showed that the flow-through system could reduce L. monocytogenes in brine by 1 log cfu/ml within 5 s, and could eliminate L. monocytogenes in recirculated chilling brine after 30 min operation. At the same time, electrolyzed water was investigated for antimicrobial treatment of chicken carcasses and chilling water to reduce S. Typhimurium and C. jejuni. The electrolyzed water reduced pathogenic bacteria on broiler carcasses by 2-3 log after 30 s spraying or 45 min chilling. Antimicrobial spray, using cetylpyridinium chloride or electrolyzed water was investigated for inactivation of S. Typhimurium and C. jejuni attached to chicken carcasses in processing, and more than 2 log reduction could be achieved with optimized temperature, pressure and time.
The antimicrobial technology research was supported by USDA/CSREES, EPRI/FTC, Food Safety Consortium, USPEA and industries including ALKAR, Tyson Foods, Simmons Foods, Electrochemical Technologies, Monsanto, and Johnson Food Equipment. The research in antimicrobial technology resulted in 4 US patents issued and 1 pending, four of which are licensed by Safe Food Corp.
