Acid adaptation of<i>Lactobacillus delbrueckii</i>subsp.<i>bulgaricus</i>induces physiological responses at membrane and cytosolic levels that improves cryotolerance

Abstract

This study increased knowledge concerning the physiological mechanisms that explained the cross-protection by acid adaptation. It may be useful for improving cryotolerance of lactic acid bacteria, either in cells banks or in an industrial context.
