Nisin-controlled expression of Norwalk virus VP60 protein in Lactobacillus casei.
A food-grade strain with nisRK stably integrated into the genome, was constructed in order to implement the nisin-controlled expression system (NICE) in Lactobacillus casei ATCC393. Expression of beta-glucuronidase (gus) reporter gene was employed to optimize the system, which has been successfully used to produce the main antigenic protein from Norwalk virus, opening new perspectives for producing edible vaccines.
