Aims: To evaluate strains of Lactobacilli, Bifidobacteria and Streptococci for their ability to produce conjugated linoleic acid (CLA) from free (LA). Methods Results: Eight dairy bacteria tolerant LA were grown in MRS broth containing (200 μg ml−1) CLA was assessed. Seven able form after 24 h incubation, varying percentage conversion between 17% 36%. Lactobacillus casei, rhamnosus, Bifidobacterium bifidum Streptococcus thermophilus showed the highest inoculated into buffalo milk...
The ability to adsorb zearalenone by five strain of lactic acid bacteria was evaluated: four strains Lactobacillus spp. isolated from pig rectal swabs and one commercial (Lactobacillus rhamnosus). Several factors affecting the adsorption capacity were evaluated in order improve mycotoxin bacteria. stability zearalenone-bacteria complex analyzed. In every case, bacterial higher than 40.0%. showing highest (68.2%) selected for following steps this research. percentages obtained after...
The beneficial effect of lactobacilli has been attributed to their ability colonize human and animal gastrointestinal tracts. In this work, adhesion assays with three lactobacillus strains intestinal fragments obtained from chickens were assessed. Lactobacillus animalis L. fermentum able adhere kinds epithelial cells (crop, small large intestines) predominance intestine. Among the considered, subsp. cellobiosus showed lowest highest ability. Scanning electron microphotographs showing...
The intestinal microbiota would be implicated in pathology associated with celiac disease caused by an abnormal immune system reaction against gluten present cereal grains. objectives of this work were to detect through basic methods the changes composition most common genera bacteria from symptom-free children a gluten-free diet compared healthy Tucumán and select lactobacilli (Lb) strains probiotic potential feces children. Results demonstrated that showed significantly lower counts Lb (P...
The aim of this work was to study the fatty acid profile pig meat after probiotic administration. Thirty postweaned pigs (25 day old) were distributed into 2 groups: control (n = 15) and 15). Each experimental group fed ad libitum on a commercial diet for 35 days. Lactobacillus amylovorus Enterococcus faecium mixed culture (108 CFU/ml)was daily orally delivered group. At end assay, six randomly selected from each slaughtered muscle samples (Longissimus dorsi) taken analysis. Tissues animals...
Obesity induces local/systemic inflammation accompanied by increases in macrophage infiltration into adipose tissue and production of inflammatory cytokines, chemokines, hormones. Previous studies have shown that probiotics could improve the intestinal dysbiosis induced metabolic diseases such as obesity, diabetes, syndrome. Microorganisms (directly or indirectly) affect adipokine levels due to their capacity induce translocation several microbial antigens systemic circulation, which lead...
This work investigated chloroform extracts from culture supernatants of two human probiotic bacteria, Lactobacillus casei CRL 431 and acidophilus 730 for the production virulence factors quorum sensing (QS) interference against three Pseudomonas aeruginosa strains. Both inhibited biofilm biomass (up to 50%), metabolic activity 39%), enzyme elastase 63%) pyocyanin 77%), decreased QS, without presenting any antibacterial acgivity. In addition, both strains disrupted preformed biofilms P....
The protective effect of feeding milk fermented with a mixture Lactobacillus casei and Lact. acidophilus against Shigella sonnei was studied. There 100% survival rate in mice fed for 8 d then dosed orally Sh. sonnei. control approximately 60% after 21 d. Colonization the liver spleen markedly inhibited by pretreatment milk. Differences cell counts 2–3 log units between treated were always obtained, shigellas not detected these organs 10th day mice, while high levels maintained controls....
The effect of different fermenting microorganisms on growth a mycotoxin- producing Aspergillus nomius was assayed. Two lactic acid bacteria, Lactobacillus fermentum and rhamnosus, Saccharomyces cerevisiae, all which are widely used in fermentation preservation food, were assayed their fungus inhibitory properties. Assays carried out by simultaneous inoculation one the possible inhibiting or subsequent followed fungus. All three showed inhibition mycotoxin-producing strain. L. rhamnosus O236,...
