Nitrite stress acclimation of Pediococcus pentosaceus improves nitrite degradation in fermented sausages: from phenotype to transcriptomic mechanism.

Abstract excerpt

Nitrite is a widely used additive in processed meat products, but its excessive accumulation raises serious safety concerns due to the formation of carcinogenic N-nitrosamines. Lactic acid bacteria as starter cultures have been explored for nitrite removal, but their efficiency is often limited under nitrite stress. In this study, to improve nitrite degradation performance, stepwise adaptive evolution of...
