The beneficial properties of lactic acid bacteria have been extensively studied and there is scientific evidence that support their use as food microbial supplements.Sorne potential probiotic clearly demonstrated for lactobacilli other genera but not propionibacteria (PAB).This article reports the effect feeding on composition metabolic activity intestinal microflora related to faecal enzymes involved in release carcinogenic compounds.The studies were carried out with four strains...

Different studies in animal rearing claim the probiotic potential of species genus Propionibacterium . The effects strains acidipropionici isolated from poultry intestine on microbiota activity and intestinal mucosa development were investigated early stage chicks safety dose used was investigated. P. LET105 LET107, administered as monoculture to 1 st 14 th day life a daily 106 cfu/ml drinking water resulted harmless. animals arrived at expected weight for age no differences observed with...

Adhesion to the intestinal mucosa is generally considered an important property of probiotic microorganisms and has been related many their health benefits. This study investigated some factors that could affect or be involved in adherence Propionibacterium acidipropionici CRL 1198, a dairy strain with suggested effects high vitro vivo epithelial cells. In adhesion propionibacteria was decreased by gastric digestion but not affected bile pancreatic enzymes. Adherence also pretreatment...

Plant lectins, which are proteins/glycoproteins present in a wide range of vegetables, fruits, cereals and beans, resistant to digestive enzymes food cooking temperatures. They bind reversibly specific glycosidic residues expressed on the membrane intestinal epithelial cells (IEC) cause anti-nutritional effects humans animals. Soybean lectin (SBA) has been detected poultry diets, its ability epithelium reported. The development new methods for removing SBA from feeds or prevent interaction...

The genus Propionibacterium consists of two principal groups, cutaneous and classical or dairy. Cutaneous species are predominant members the microbial population human skin have also been isolated from feces humans other vertebrate animals. They often considered opportunistic organisms occasionally associated with infections in humans. Dairy propionibacteria microorganisms extensively used industry for manufacture Swiss-type cheeses biological production propionic acid vitamin B12. can be...

In the present study, effect of bile on growth, cell permeabilization and β-galactosidase activity dairy propionibacteria was determined.Two groups strains with different behavior in media oxgall (dehydrated fresh bile) could be observed, were named bile-tolerant non groups.The increased during growth containing 0.15 0.30% oxgall.The incubation suspensions phosphate buffer all studied strains.They permeabilized by bile, permitting more substrate to enter cells hydrolyzed β-galactosidase.A...

The supply of carbohydrates is a growth-limiting factor for the intestinal microflora which ferments non-digested or incompletely digested carbohydrates, rendering short-chain fatty acids (SCFA) as major products.These organic are involved in wide range physiological functions.Therefore, it great interest to increase SCFA production by using probiotic strains.The aim this study was assess vitro and vivo contribution four strains propionibacteria lactic acid mouse cecum, determine viability...

ABSTRACT Chemical properties, long chain fatty acid composition and conjugated linoleic (CLA) content of buffalo cheese were determined. Good nutritional properties observed in cheese, showing 11.5% protein, 18.3% fat 30.5% dry matter. Saturated was 65.6%, monounsaturated 31.8% polyunsaturated 2.6%. Stearic (C16:0) oleic (C18:1) acids the major (FAs) present milk cheese. Values slightly higher CLA determined (4.5 5.2 mg/g fat, respectively), being cis ‐9, trans ‐11, predominant isomer. Mice...

To assess in vitro the ability of some dairy bacteria to bind concanavalin A (Con A), peanut agglutinin (PNA) and jacalin (AIL), preventing their toxicity on mouse intestinal epithelial cells (IEC).Con AIL reduced significantly IEC viability vitro, as determined by Trypan Blue dye exclusion or propidium iodide/fluorescein diacetate/Hoescht staining. Different strains were able remove lectins from media. Two subjected treatments used S-layer, cell wall proteins, polysaccharides lectin-like...

Ferulic acid esterase (FAE+)-producing lactobacilli are being studied as silage inoculants due to their potential of increasing forage fiber digestibility. In this work, three FAE+ Lactobacillus (L.) johnsonii strains were isolated from caprine feces and characterized according probiotic characteristics inoculants. Limosilactobacillus fermentum CRL1446, a human goat cheese, was also included in the experiments inoculant. FAE activity quantification, characterization, growth maize aqueous...

The ban on the use of antibiotics as feed additives for animal growth promotion in European Union and United States expectation this trend to further expand other countries short term have prompted a surge probiotic research. Multi-species probiotics including safe compatible strains with ability bind different nutritional lectins detrimental effects poultry nutrition could replace additives. Lactobacillus salivarius LET201, reuteri LET210, Enterococcus faecium LET301, Propionibacterium...
