Functional analysis of putative adhesion factors in Lactobacillus acidophilus NCFM.
Lactobacilli are major inhabitants of the normal microflora of the gastrointestinal tract, and some select species have been used extensively as probiotic cultures. One potentially important property of these organisms is their ability to interact with epithelial cells in the intestinal tract, which may promote retention and host-bacterial communication. However, the mechanisms by which they at...
متن کاملCharacterization of the tre locus and analysis of trehalose cryoprotection in Lactobacillus acidophilus NCFM.
Freezing and lyophilization are common methods used for preservation and storage of microorganisms during the production of concentrated starter cultures destined for industrial fermentations or product formulations. The compatible solute trehalose has been widely reported to protect bacterial, yeast and animal cells against a variety of environmental stresses, particularly freezing and dehydra...
متن کاملInfluence of the Probiotic Lactobacillus acidophilus NCFM and Lactobacillus rhamnosus HN001 on Proteolysis Patterns of Edam Cheese.
The objective of this study is to determine the viability of Lactobacillus acidophilus NCFM and Lactobacillus rhamnosus HN001 in Edam cheese as well as the effect of probiotic bacteria on paracasein proteolysis and changes in the water activity during ripening. The use of probiotics L. rhamnosus HN001 and L. acidophilus NCFM in Edam cheese slightly changed its chemical composition, but the chan...
متن کاملEffects of Lactobacillus acidophilus NCFM on insulin sensitivity and the systemic inflammatory response in human subjects.
According to animal studies, intake of probiotic bacteria may improve glucose homeostasis. We hypothesised that probiotic bacteria improve insulin sensitivity by attenuating systemic inflammation. Therefore, the effects of oral supplementation with the probiotic bacterium Lactobacillus acidophilus NCFM on insulin sensitivity and the inflammatory response were investigated in subjects with norma...
متن کاملTranscriptional Analysis of Prebiotic Uptake and Catabolism by Lactobacillus acidophilus NCFM
The human gastrointestinal tract can be positively modulated by dietary supplementation of probiotic bacteria in combination with prebiotic carbohydrates. Here differential transcriptomics and functional genomics were used to identify genes in Lactobacillus acidophilus NCFM involved in the uptake and catabolism of 11 potential prebiotic compounds consisting of α- and β-linked galactosides and g...
