16S-Amplified Ribosomal DNA Restriction Analysis Assay for Discriminating Potentially Probiotic Lactobacillus Species Isolated from Traditional Dairy Products
Background: Traditional dairy products are the main sources for probiotic bacteria. This study aimed to isolate and characterize the potentially probiotic Lactobacillus strains isolated from traditional dairy products in Iran. Methods: Microbial population of each dairy product was enriched and screened for acid- and bile- resistant strains. The isolates were ...
متن کاملIdentification and Characterization of Lactic Acid Bacteria Isolated from Iranian Traditional Dairy Products
The lactic acid bacteria (LAB) are an industrially important group of probiotic organisms that play an important role in human health by inhibiting harmful and pathogen bacteria growth, boosting immune function, and increasing resistance to infection. This study aimed to isolate, identify, and biologically characterize probiotic LAB strains from Iranian traditional dairy products. A ...
متن کاملGenotypic and Phylogenic Analysis of Lactobacilli Producing Bacteriocin Isolated from Traditional Dairy Products and Food
Background & Objective: Lactic acid bacteria (LAB) are a group of Gram-positive, non-spore forming, cocci or rod shaped, catalase negative organisms, considered as Generally Recognized as Safe (GRAS) organisms. These bacteria are used for thousands of years for production of fermented foods because of their ability to produce desirable changes in taste, flavor and texture. Different antimicrobi...
متن کاملMolecular characterization of Pasteurella multocida isolates obtained from poultry, ruminant, cats and dogs using RAPD and REP-PCR analysis
In the present study, Randomly Amplified Polymorphic DNA (RAPD) and Repetitive Extragenic Palindromic sequence-based Polymerase Chain Reaction (REP-PCR) were used to characterize 131 isolates of Pasteurella multocida, originating from different healthy and diseased animal species obtained from several geographical regions of Iran. The RAPD and REP-PCR generated amplified products in the range ...
متن کاملMolecular investigation of the prevalence and detection of enterohemorrhagic Escherichia coli isolated from traditional cheese in Iran
Introduction: Shiga toxin-producing Escherichia coli (STEC) strains are one of the main causes of food poisoning and diseases such as hemorrhagic colitis and hemolytic uremic syndrome. Food contamination mainly occurs through food of animal origin such as meat and dairy products. The aim of this study was to investigate prevalence and distribution of virulence genes in Escherichia coli isolate...
