Background and Objectives: Nowadays, extruded snacks are the most common form of meals; however, their high amount of salt and fat leads to increase disease risk. Their coating would be a proper carrier for probiotics and has an appropriate potential for enhancement of the nutritional properties of puffed snacks. In this research, production of symbiotic snack coating by probiotic bacteria, as ...
Lactobacillus ruminis is one of at least twelve motile but poorly characterized species found in the genus Lactobacillus. Of these, only L. ruminis has been isolated from mammals, and this species may be considered as an autochthonous member of the gastrointestinal microbiota of humans, pigs and cows. Nine L. ruminis strains were investigated here to elucidate the biochemistry and genetics of L...
Nowadays, there is increasing interest in the production of functional foods, particularly probiotic foods. Lactic acid bacteria (LAB) particularly strains of Lactobacillus are important bacteria in food microbiology and human nutrition due to their ability to fermented food production and have received considerable attention as probiotics. The traditional fermented dairy foods as a rich source...

179 باکتری از 9 نمونه شیر شتر جداسازی و از لحاظ ویژگی های فنوتیپی و مولکولی شناسایی شدند. براساس آنالیز ardra در نواحی 16s rdna و its، جدایه ها به 12 الگوی مختلف گروه بندی شدندکه توسط توالی یابیdna ریبوزومی به عنوان pediococcus pentosaceus, enterococcus lactis, enterococcus hirae, enterococcus faecium bibt_vc, enterococcus faecium ccmmb, enterococcus mundtii, enterococcus durans, lactobacillus ...
Sortase-dependent surface pili (or fimbriae) in Gram-positive bacteria are well documented as a key virulence factor for certain harmful opportunistic pathogens. However, it is only recently known that these multi-subunit protein appendages are also belonging to the "friendly" commensals and now, with this new perspective, they have come to be categorized as a niche-adaptation factor as well. I...
Biomimetic in vitro intestinal models are becoming useful tools for studying host-microbial interactions. In the past, these models have typically been limited to simple cultures on 2-D scaffolds or Transwell inserts, but it is widely understood that epithelial cells cultured in 3-D environments exhibit different phenotypes that are more reflective of native tissue, and that different microbial...
It is estimated that most colon cancers can be attributed to dietary causes. We have hypothesized that diet influences the health of the colonic mucosa through interaction with the microbiota and that it is the milieu interior that regulates mucosal proliferation and therefore cancer risk. To validate this further, we compared colonic contents from healthy 50- to 65-y-old people from population...
