Microorganisms encounter acid stress during multiple bioprocesses. Microbial species have
therefore developed a variety of resistance mechanisms. The damage caused by acidic …

Lactic acid bacteria (LAB) are important starter, commensal, or pathogenic microorganisms.
The stress physiology of LAB has been studied in depth for over 2 decades, fueled mostly by …

This research effort aimed at isolating and phenotypically characterizing lactic acid bacteria
(LAB) isolates from a spontaneous rye sourdough manufactured following traditional …

Metabolites, substrates and substrate impurities may be toxic to cells by damaging biological
molecules, organelles, membranes or disrupting biological processes. Chemical stress is …

The ability of bacteria to sense and respond to both environmental and intracellular metal
concentrations plays an important role in pathogenesis. The acquisition of manganese is …

To be able to function as a probiotic, bacteria have to survive the passage through the
gastrointestinal tract. We have examined survival and gene expression of Lactobacillus …

Tolerance to acid is an important feature for probiotic bacteria during transition through the
gastrointestinal tract. Proteomics analysis of a new probiotic bacterium, Lactobacillus casei …

Lactic acid bacteria (LAB) have taken centre stage in perspectives of modern fermented food
industry and probiotic based therapeutics. These bacteria encounter various stress …

Group B streptococcus (GBS) is a leading cause of neonatal mortality and morbidity in the
United States and Europe. It is part of the vaginal microbiota in up to 30% of pregnant …
