Phage-like Structures from Lactobacillus acidophilus

Characterization of Rhamnosidases from Lactobacillus plantarum and Lactobacillus acidophilus.

Lactobacilli are known to use plant materials as a food source. Many such materials are rich in rhamnose-containing polyphenols, and thus it can be anticipated that lactobacilli will contain rhamnosidases. Therefore, genome sequences of food-grade lactobacilli were screened for putative rhamnosidases. In the genome of Lactobacillus plantarum, two putative rhamnosidase genes (ram1(Lp) and ram2(L...

Complete Genome Sequence of Lactobacillus acidophilus FSI4, Isolated from Yogurt

A new Lactobacillus acidophilus strain, FSI4, isolated from yogurt, was isolated and sequenced in our laboratory. Our data, although supportive of previous conclusions regarding the remarkable stability of L. acidophilus species, indicate accumulating mutations in commercial L. acidophilus strains that warrant further study of the effect of damaged genes on the competitiveness of these bacteria...

Characterization of Lactobacillus acidophilus Isolated from Piglets and Chicken

Lactic acid bacteria were isolated from piglets and chicken and characterized. Lactic acid bacteria showing resistance to low pH and bile, adhesion to intestinal epithelium cells, and the inhibition of Escherichia coli and Salmonella spp. were identified as Lactobacillus acidophilus. L. acidophilus PF01 survived for 2 h in MRS broth adjusted to pH 2. L. acidophilus CF07 was less resistant than ...

Lactobacillus acidophilus, and Lactobacillus plantarum occur naturally in the human

Lactobacillus acidophilus—Rutin Interplay Investigated by Proteomics

Dietary polyphenols are bioactive molecules that beneficially affect human health, due to their anti-oxidant, anti-inflammatory, cardio-protective and chemopreventive properties. They are absorbed in a very low percentage in the small intestine and reach intact the colon, where they are metabolized by the gut microbiota. Although it is well documented a key role of microbial metabolism in the a...
