The latest deal, which includes a DuPont Ventures equity investment, will give DuPont exclusive, worldwide rights to the technologies for food and food protection applications.

AvidBiotics antibacterial technology is based on R-type bacteriocins i.e. proteins with bactericidal activity, according to Ingredients Network.

The R-type bacteriocins may be developed against any spoilage organism of interest or pathogenic bacteria.

AvidBiotics president and director said the R-type bacteriocin technology’s specificity is the big advantage for food applications.

"Compared to antibiotics, which often kill beneficial and harmful bacteria alike, these proteins can be engineered to attack with precision," Knighton added.

"Ensuring the safety, freshness and quality of products throughout shelf life is at the top of the food industry agenda, and we are excited by the prospect of broadening our food protection offering to help meet these challenges," said

Fabienne Saadane-Oaks, leader of the Health & Protection division at DuPont Nutrition & Health said, "Investing in unique and novel technologies such as these is a great fit with the Food Security Goals recently announced by DuPont to improve the safety and quality of the global food supply."
