  • strains
  • A new high-throughput culturing (HTC) method using a low nutrient heterotrophic medium (LNHM) has led to the isolation of many novel strains of oligotrophic bacteria from marine ecosystems. (oregonstate.edu)
  • intestinal
  • This pathway, called the bifid shunt, uses the key enzyme frutose-6-phosphate phosphoketolase (F6PPK) and is the generally used as a diagnostic test for this Bifidobacteria because it's not found in other gram-positive intestinal bacteria. (kenyon.edu)
  • Bifidobacteria exert a range of beneficial health effects, including the regulation of intestinal microbial homeostasis, the inhibition of pathogens and harmful bacteria that colonize and/or infect the gut mucosa, the modulation of local and systemic immune responses, the repression of procarcinogenic enzymatic activities within the microbiota, the production of vitamins, and the bioconversion of a number of dietary compounds into bioactive molecules. (kenyon.edu)
  • Their use, in conjunction with traditional culturing methods, has led to a polyphasic taxonomy which has significantly enhanced our knowledge of the role played by these bacteria in the human intestinal ecosystem. (springer.com)
  • microbial
  • The prehydrolysate produced from wood also contained toxins, primarily lignin and sugar degradation products, which strongly inhibited the microbial and the enzymatic reactions. (ncsu.edu)
  • enzyme
  • The PTS consists of two general components, enzyme I (EI) and histidine phosphocarrier protein (HPr), and of membrane-bound sugar specific permeases (enzymes II). (genome.jp)
  • A novel bifunctional enzyme, L-rhamnulose-phosphate aldolase (RhaE) fused to L-lactaldehyde dehydrogenase (RhaW), which is not homologous to previously characterized L-Rha catabolic enzymes, was identified in diverse bacteria including Chloroflexi, Bacilli, and Alphaproteobacteria. (frontiersin.org)
  • The enzyme is antibacterial because it degrades the polysaccharide that is found in the cell walls of many bacteria. (biology-pages.info)
  • carbon
  • They constitute a large fraction of the reduced carbon reservoir in the ocean and enhance the survival of marine bacteria influencing the physicochemical environment in proximity of the bacterial cell. (mdpi.com)
  • As carbo - hydrates , sugars are made up of carbon ( C ) and water, which is composed of hydrogen ( H ) and oxygen ( O ). The hydrogen and oxygen atoms are arranged in various configurations around a chain of carbon atoms which form the structural backbone of the molecule. (thefreshloaf.com)
  • The carbon chain may be various lengths, but sugars common in bread fermentations are of the 5- and 6- carbon types, referred to generically as pent oses and hex oses, respectively. (thefreshloaf.com)
  • Glucose is a hexose sugar, which means that it is a monosaccharide with 6 carbon atoms and 6 oxygen atoms. (statpearls.com)
  • It is critical to remember that in this phase there are a total of 2 3-carbon sugars for every 1 glucose in the beginning. (statpearls.com)
  • Hundreds of monomers bonded together to form the molecule Organic molecules are molecules containing Carbon and Hydrogen Chapter 2: Functional Groups What is a functional Group? (prezi.com)
  • bacterial
  • Type IV pili (Tfp), which are key virulence factors in many bacterial pathogens, define a large group of multipurpose filamentous nanomachines widespread in Bacteria and Archaea. (imperial.ac.uk)
  • In conclusion, dietary FCB decreased the abundance of bacterial communities, particularly the population of bacteria related to cellulolytic degradation. (frontiersin.org)
  • Bifidobacteria , called probiotics, are a natural part of the bacterial flora in the human body and have a symbiotic bacteria-host relationship with humans. (kenyon.edu)
  • it is thought that Bifidobacterium's ability to compete with other gastrointestinal bacteria and occupy a large percentage in the bacterial flora of the gastrointestinal region might be partly due to the large variety of molecules that it is able to use for energy (Schell et al . (kenyon.edu)
  • Sugars play an important role in biology by either forming conjugates with other biomolecules (e.g., glycoproteins) or by mediating cell surface recognition events (e.g., bacterial or viral binding to cells). (thefreedictionary.com)
  • symbiotic
  • The aim of this paper is to give an overview of current knowledge on EPSs produced by marine bacteria including symbiotic marine EPS-producing bacteria isolated from some marine annelid worms that live in extreme niches. (mdpi.com)
  • intestine
  • While Bifidobacterium infantis, B. brevi, and B. longum are the largest group of bacteria in the intestine of infants, Bifidobacteria are said to be only the 3rd or 4th largest group in adults (and comprise only 3-6% of adult fecal flora). (kenyon.edu)
  • molecule
  • A functional group is a specific group of atoms within molecules that are responsible for characteristic chemical reactions of that molecule. (prezi.com)
  • A hydroxyl group makes it a polar molecule able to form hydrogen bonding with water and itself. (prezi.com)
  • residues
  • EIIA catalyzes the self-phosphoryl transfer from HPr after which the phosphoryl group is transferred to histidine or cysteine residues of EIIB. (genome.jp)
  • Bifidobacteria
  • When breast-fed infants' diets are changed to cows milk and solid food, Bifidobacteria are joined by rising numbers of other bacteria found in the human body such as Bacteroides and Streptococci lactobacilli . (kenyon.edu)
  • species
  • Type IV pili (Tfp), which have been studied extensively in a few Gram-negative species, are the paradigm of a group of widespread and functionally versatile nano-machines. (imperial.ac.uk)
  • biological
  • Biofilms are aggregates of one or more types of bacteria attached to a biological or inert surface and encased in a glycocalyx or matrix. (asm.org)
  • yeast
  • Eating substances rich with these probiotics is a sort of home remedy for diarrhea, vaginitis, and yeast infections because it promotes the growth of these as opposed to other bacteria. (kenyon.edu)
  • In yeasted breads, acids come in small doses from naturally occurring bacteria present in flour and commercial yeast. (thefreshloaf.com)
  • You're right about the bacteria count over yeast - leavaning of loaves is problematic. (thefreshloaf.com)
  • growth
  • Many marine bacteria produce exopolysaccharides (EPS) as a strategy for growth, adhering to solid surfaces, and to survive adverse conditions. (mdpi.com)
  • Additionally, acetate may have a negative effect on bioleaching by inhibiting the growth of chemolithotrophic bacteria. (biomedcentral.com)
  • Their growth characteristics showed that these bacteria were slowly growing, obligate or facultative oligotrophic and psychro-tomesophilic bacteria. (oregonstate.edu)
