The Bacillus subtilis strain VTT E-68013 was chosen for purification and characterization of its excreted phytase. Purified enzyme had maximal phytase activity at pH 7 55 degrees C. Isolated required calcium and/or stability readily inhibited by EDTA. proved to be highly specific since, the substrates tested, only phytate, ADP, ATP were hydrolyzed (100, 75, 50% relative activity, respectively). gene (phyC) cloned from B. genomic library. deduced amino acid sequence (383 residues) showed no...

ABSTRACT A DNA-based, direct method for initial characterization of the total bacterial community in ileum and cecum chicken gastrointestinal (GI) tract was developed. The efficiencies extraction lysis were >95 >99%, respectively, therefore DNA recovered should accurately reflect communities ileal cecal digesta. Total samples fractionated according to their percent G+C content. profiles reflecting composition reproducible within each compartment, but different between compartments GI...

ABSTRACT Inulin is a well-known fructose-based prebiotic which has been shown to stimulate the growth of bifidobacteria, bacterial group generally considered beneficial for intestinal health. In present study, we analyzed inulin-associated shifts in total community wild-type mice and carrying genetically inactivated adenomatous polyposis coli tumor suppressor gene by using DNA-based approaches independent culturability. Mice were fed high-fat, nonfiber diet with or without inulin inclusion...

The aim of the present work was to compare efficacies and levels selectivity different culture-dependent -independent methods for analyzing bifidobacteria in human stool samples. three culture media used here significantly differed from each other, particularly with regard recovery Bifidobacterium adolescentis. medium failed recover B. adolescentis; Beerens recovered some adolescentis organisms (17% total bifidobacteria), whereas tomato-Eugon mainly (58% bifidobacteria). A...

A 4-stage colon simulator and a cell culture-based human intestinal epithelial function model were combined to study the effects of soluble fiber, polydextrose (PDX), on microbes mucosal functions relevant risk cancer. We observed sustained degradation PDX throughout different stages model. The fermentation was characterized by gradual PDX, production short-chain fatty acids, no increasing in putrefactive markers. less marked microbial densities. When we applied metabolites obtained from...

Phytase is commonly used as a feed enzyme in monogastric animals to increase the bioavailability of phytate phosphorus and other nutrients. The accumulation myo-inositol phosphate intermediates during degradation various segments gastrointestinal tract (GIT) poorly understood. aim this study was determine efficacy Buttiauxella spp. phytase degrading corn, soybean meal, complete corn-soybean meal diet esters (IP1-IP5) completely dephosphorylated rings using an vitro model poultry upper GIT....

As plant-based diets become more popular, there is an interest in developing innovations to improve the bioaccessibility of plant protein. In this study, seven probiotic strains (Bifidobacterium animalis subsp. lactis B420, B. Bl-04, Lactobacillus acidophilus NCFM, Lacticaseibacillus rhamnosus HN001, paracasei Lpc-37, Lactiplantibacillus plantarum Lp-115, and Lactococcus Ll-23) were evaluated for their capacity hydrolyze soy pea protein ingredients vitro digestion model upper...

An in vitro model of the upper gastrointestinal tract as well chicken cecum was developed to have a predictive tool for estimating production performance animals by analyzing feeding value certain diet. The consists batch type model, whereas cecal is comprised 4 semi-continuous connected vessels inoculated with or fecal microbes. and simulations were both run corn- wheat-based diet simulate 2 typical feed types. Samples collected after 5-h aliquots frozen assess inoculum stability....

Maidon erityksen alkaessa lypsylehmän energian ja ravintoaineiden tarve lisääntyy nopeasti lehmä alkaa mobilisoida kudoksistaan rasva­ aminohappoja. Voimakas kudosmobilisaatio lisää aineen­vaihduntasairauksien riskiä.
