توکسینزدایی میکروبی یکی از روشهای حذف آفلاتوکسینها از جمله آفلاتوکسین M1 محسوب میشود. گزارشها نشان دهنده آن است که برخی از سویههای باکتریهای خانواده اسید لاکتیک از طریق جذب سطحی آفلاتوکسینها به دیواره سلولی خود، میتوانند در حذف آنها مؤثر باشند. در این تحقیق توانایی باکتری Bifidobacterium bifidum در میزان جذب آفلاتوکسین M1 از ماست پروبیوتیک بررسی گردید. بدین منظور حدود cfu/ml 108 از ب...
Introduction: Consumption of appropriate amount of probiotic microorganisms via food products have health benefits on the host. In recent years, there has been a significant increase in research on the characterization and verification potential use of probiotic films in food industry. The aim of the current study was to investigate in vitro antimicrobial property of p...
BACKGROUND Atopic dermatitis, a chronic recurrent disease, is frequently encountered in clinical practice. In the last 30 years, the prevalence of atopic dermatitis has rapidly increased due to industrialization. Therefore, there have been attempts in recent years to find new ways of treating and preventing atopic dermatitis. OBJECTIVE In this double-blind, randomized, placebo-controlled stud...
Binding of the lipoteichoic acids of Bifidobacterium bifidum to human colonic epithelial cells appeared to be specific, reversible, and cell concentration and time dependent. A single population of approximately 8.3 X 10(8) binding sites per cell was detected, with a dissociation constant of 125 microM. Ester-linked fatty acids are essential for binding.
Gnotobiotic mice died 2 days after inoculation of a cytotoxigenic Clostridium difficile strain. Protection occurred when mice were previously inoculated with a strain of Escherichia coli or Bifidobacterium bifidum. Intestinal cytotoxin production was highly reduced in the surviving mice, whereas the C. difficile population level did not decrease to a great extent.
Two lacto-N-biose phosphorylase (LNBP) isozyme genes were cloned from Bifidobacterium bifidum JCM1254. Alignment of the amino acid sequences of LNBP and its homologs identified 24 completely conserved acidic amino acid residues. All single mutants of Bifidobacterium longum LNBP at residues other than D313N retained considerable activity, suggesting that Asp313 is the putative proton donor resid...
We assessed the effect of multi-species probiotic mixture on the changes in fecal microbiota and irritable bowel syndrome (IBS) symptoms. Eighty-one IBS patients were randomly assigned to receive either probiotic mixture (n = 39; containing Lactobacillus acidophilus, L. rhamnosus, Bifidobacterium breve, B. actis, B. longum, and Streptococcus thermophilus) or placebo (n = 42) for 4 weeks. A ques...
Resveratrol exerts several pharmacological activities, including anti-cancer, anti-inflammatory, cardioprotective, or antioxidant effects. However, due to its occurrence in plants more in glycosidic form as piceid, the bioavailability and bioactivity are limited. The enzymatic potential of probiotics for the transformation of piceid to resveratrol was elucidated. Cell extract from Bifidobacteri...
