Lactobacillus acidophilus is a commercially significant bacterial probiotic, originally isolated from the human gastrointestinal tract and designated Bacillus acidophilus in 1900. Throughout the development of methods to identify and characterise bacteria, L. acidophilus has undergone multiple taxonomic revisions and is now the type species of a phylogenetic subgroup in the highly diverse and h...

At the 1920 meeting of the Society of American Bacteriologists a paper, published only in abstract form (Sherman, 1921), presented some characteristics of Lactobacillus bulgaricus, differentiating this organism from certain other lactobacilli. Eighteen cultures of Lactobacillus bulgaricus were then studied; a number of Lactobacillus casei; a few cultures from feces, assumed to belong to the Lac...

this study investigated the survival of a probiotic strain of lactobacillus acidophilus (la-5) in jug cheese during storage (120 days at 6-8 °c). the jug cheese treatments were: c (control), containing commercial starter frc-65; la, containing lactobacillus acidophilus; and las, containing commercial starter and lactobacillus acidophilus. the results showed that the amount of lactobacillus acid...

Probiotics are bacteria that are commercially available as dietary supplements. One of the important properties of probiotics is their ability to survive in the intestine. Recent evidence has identified kynurenic acid (KYNA) as a bactericidal constituent of intestinal fluid. These data led us to study the influence of KYNA on the viability of selected probiotics. We found that KYNA supported th...

AIMS This study was undertaken to evaluate the oxalate-degrading activity in several Lactobacillus species widely used in probiotic dairy and pharmaceutical preparations. Functional characterization of oxalyl-CoA decarboxylase and formyl-CoA transferase in Lactobacillus acidophilus was performed in order to assess the possible contribution of Lactobacillus in regulating the intestinal oxalate h...

Probiotic Lactobacillus acidophilus L-55 was isolated from a healthy human gut. Here, we report the draft genome sequence of this organism.

Lactobacillus acidophilus 30SC has been isolated from swine intestines and considered a probiotic strain for dairy products because of its ability to assimilate cholesterol and produce bacteriocins. Here, we report the complete genome sequence of Lactobacillus acidophilus 30SC (2,078,001 bp) exhibiting strong acid resistance and enhanced bile tolerance.

Three strains of Lactobacillus, identified as Lactobacillus acidophilus, Lactobacillus gasseri, and Lactobacillus jensenii, were selected from among 70 isolates from the vaginas of healthy premenopausal women for properties relevant to mucosal colonization or antagonism. All three self-aggregated and adhered to epithelial vaginal cells, displacing well-known vaginal pathogens, such as G. vagina...
