TL;DR: The major S layer protein, SlpA, of L. acidophilus NCFM is the first probiotic bacterial DC-SIGN ligand identified that is functionally involved in the modulation of DCs and T cells functions.
Journal ArticleDOI

TL;DR: In this article, P freudenreichii subsp shermanii CIRM-BIA1 (CIP 103027T) was sequenced with an 11-fold coverage.
The complete genome of Propionibacterium freudenreichii CIRM 1 a hardy actinobacteria with food and probiotic applications
Hélène Falentin,Stéphanie-Marie Deutsch,Sandrine Parayre-Breton,Julien Dherbécourt,Gwénaël Jan,Anne Thierry,Marie-Bernadette Maillard,Fabien J. Cousin,Valentin Loux,Julien Jardin,Patricia Siguier,Arnaud Couloux,Valérie Barbe,Patrick Wincker,Sylvie Lortal +14 more
TL;DR: The annotation revealed the genetic basis for the hardiness of P. freudenreichii, as the bacterium possesses a complete enzymatic arsenal for de novo biosynthesis of aminoacids and vitamins as well as sequences involved in metabolism of various carbon sources, immunity against phages, duplicated chaperone genes and, interestingly, genes involved in the management of polyphosphate, glycogen and trehalose storage.
Journal ArticleDOI
S-layer of Lactobacillus helveticus ATCC 12046: isolation, chemical characterization and re-formation after extraction with lithium chloride
TL;DR: Freeze-etched preparations of intact cells have demonstrated that this protein layer is an oblique surface layer (S-layer) lattice which completely covers the cell surface.
Journal ArticleDOI
Role, mechanisms and control of lactic acid bacteria lysis in cheese
TL;DR: The different methods used to detect starter lysis in situ and current knowledge concerning the impact of lysis on cheese ripening are described, particularly the increase of free amino acids due to early lysis and the reduction of bitterness by hydrolysis of large hydrophobic peptides.
