A bacterial strain isolated from intestines of hybrid catfish (Clarias gariepinus Male × Clarias macrocephalus Female) exhibited an in vitro inhibitory effect on a fish pathogen, Aeromonas hydrophila TISTR 1321. By using the 16S rDNA sequence analysis, it was identified as Lactobacillus plantarum C014. To examine whether L. plantarum C014 had potential for use as an immunostimulant and biocontr...
Lactobacillus plantarum species is a good source of esterases since both lipolytic and esterase activities have been described for strains of this species. No fundamental biochemical difference exists among esterases and lipases since both share a common catalytic mechanism. L. plantarum WCFS1 possesses a protein, Lp_3561, which is 44% identical to a previously described lipase, Lp_3562. In con...
This study aimed to investigate the anti-obesity effects of yogurt fermented by Lactobacillus plantarum Q180 in diet-induced obese rats. To examine the effects, male Sprague-Dawley rats were fed on six different diets, as follows: Group A was fed an ND and orally administrated saline solution; Group B, an HFD and orally administrated saline solution; Group C, an HFD and orally administrated yog...
The 3,308,274-bp sequence of the chromosome of Lactobacillus plantarum strain WCFS1, a single colony isolate of strain NCIMB8826 that was originally isolated from human saliva, has been determined, and contains 3,052 predicted protein-encoding genes. Putative biological functions could be assigned to 2,120 (70%) of the predicted proteins. Consistent with the classification of L. plantarum as a ...
This study aimed to find candidate strains of Lactobacillus isolated from sheep dairy products (yogurt and ewe colostrum) with probiotic and anticancer activity. A total of 100 samples were randomly collected from yogurt and colostrum and 125 lactic acid bacteria were isolated. Of these, 17 Lactobacillus strains belonging to five species (L. delbrueckii, L. plantarum, L. rhamnosus, L. paracasei...
lactobacillus spp are a group of gram-positive, non-spore forming, cocci or rod shaped, catalase negative organisms that benefit to the host. prebiotics are non-digestible food ingredients that stimulate the growth and /or activity of bacteria in the digestive system in ways claimed to be beneficial to health. this study was conducted in order to investigate the effects of selected probiotic mi...
Plantaricin EF and JK are both two-peptide bacteriocins produced by Lactobacillus plantarum C11. The mechanism of plantaricin EF and JK action was studied on L. plantarum 965 cells. Both plantaricins form pores in the membranes of target cells and dissipate the transmembrane electrical potential (Deltapsi) and pH gradient (DeltapH). The plantaricin EF pores efficiently conduct small monovalent ...
The quantification of exogenous lactobacilli in faecal samples is frequently required for the evaluation of the intestinal colonization by probiotic bacteria. In this study, a selective and differential medium, designated LPSM, was developed for the culture of exogenous Lactobacillus plantarum. In quantitative assays, LPSM showed a sensitivity similar to those of enriched and Lactobacillus-adap...
B ackground: There is limited knowledge on the extent and dynamics of the mucosal response to commensal and probiotic species in the human intestinal lumen. This study aimed to identify the acute, time-dependent responses of intestinal mucosa to commensal Lactobacillus plantarum WCFS1 in vivo in tw o placebo-controlled human intervention studies in healthy volunteers. Transcriptional changes in...
Fifteen sourdoughs produced in western Sicily (southern Italy) were analysed by classical methods for their chemico-physical characteristics and the levels of lactic acid bacteria (LAB). pH and total titratable acidity (TTA) were mostly in the range commonly reported for similar products produced in Italy, but the fermentation quotient (FQ) of the majority of samples was above 4.0, due to the l...
