background: lactobacillus plantarum isolated from fermented olives has been extensively studied with the aim of its use in starter cultures for olive or other production fermentations, but little is known about its antimicrobial resistance and its probiotic effects. objectives: the aim of this study was to determine the antimicrobial activity using different strains of l. plantarum isolated fro...

Lactobacilli with tannase activity were isolated from human feces and fermented foods. A PCR-based taxonomic assay revealed that the isolates belong to Lactobacillus plantarum, L. paraplantarum, and L. pentosus. Additional studies on a range of Lactobacillus species from established culture collections confirmed that this enzymatic activity is a phenotypic property common to these three species.

Lactobacillus species are a predominant member of the vaginal microflora and are critical in maintaining an acidic vaginal environment thought to contribute to the prevention of a number of urogenital diseases. However, during menstruation the pH of the vaginal environment increases to neutrality, a pH conducive for Staphylococcus aureus proliferation and the production of toxic shock syndrome ...

Six nicotinamide adenine dinucleotide (NAD)-dependent lactic dehydrogenases, four specific for D(-) lactate and two specific for L(+) lactate have been purified from different Lactobacillus species. Four of these enzymes appeared to be pure by several criteria. Some of the physical and catalytic properties of these enzymes are described and compared with those previously reported for the Dand L...

Among five potentially probiotic lactobacilli investigated, Lactobacillus plantarum MF1298 and Lactobacillus salivarius DC5 showed the highest increase in the transepithelial electrical resistance (TER) of polarized monolayers of Caco-2 cells, and this increase was shown to be dose dependent. Furthermore, preincubation with MF1298 attenuated a decrease in TER induced by Listeria monocytogenes.

Guo l.-d., Yang l.-J., Huo G.-Ch. (2011): Cholesterol removal by Lactobacillus plantarum isolated from homemade fermented cream in Inner Mongolia of China. Czech J. Food Sci., 29: 219–225. A total of 38 strains were initially isolated from Jiaoke, a homemade traditional fermented cream, which was sourced from Inner Mongolia, China, and 6 strains were selected after screening, which was based on...

The first comprehensive comparative analysis of lactobacilli was done by comparing the genomes of Lactobacillus plantarum (3.3 Mb) and Lactobacillus johnsonii (2.0 Mb). L. johnsonii is predominantly found in the gastrointestinal tract, while L. plantarum is also found on plants and plant-derived material, and is used in a variety of industrial fermentations. The L. plantarum and L. johnsonii ch...

background: based on literature, in vitro cholesterol removal of lactic acid bacteria has been accounted for their in vivo cholesterol reduction. but recently, it has been proposed that such in vitro characteristic may not be directly relevant to their in vivo activity. the objective of this study was to find how much in vitro cholesterol reducing potential of lactobacillus plantarum a7 (la7), ...
