Fate and impact of organics in an immersed membrane bioreactor applied to brine denitrification and ion exchange regeneration [PDF]

open access: yes, 2010
The application of membrane bioreactors (MBRs) to brine denitrification for ion exchange regeneration has been studied. The developed culture was capable of complete brine denitrification at 50 gNaCl.l−1.

Quantification of polysaccharides fixed to Gram stained slides using lactophenol cotton blue and digital image processing [version 5; referees: 2 approved, 1 approved with reservations]

open access: yesF1000Research, 2017
Dark blue rings and circles emerged when the non-specific polysaccharide stain lactophenol cotton blue was added to Gram stained slides. The dark blue staining is attributable to the presence of capsular polysaccharides and bacterial slime associated ...

Complementary Role of CD4+ T Cells in Response to Pneumococcal Polysaccharide Vaccines in Humans

open access: yesVaccines, 2019
Bacterial pathogens expressing capsular polysaccharides are common causes of mucosal infections (pneumonia, intestinal), as well as often fatal, invasive infections (meningitis, bloodstream infections) in children and adults worldwide.

Bacterial conjugation as a method for identifying the locations of genes involved in polysaccharide polymerization in Bacillus subtilis bacteria [PDF]

open access: yesمجلة التربية والعلم, 2012
The present study includes utilization of the bacterial conjugation between the local isolate Bacillus subtilis and the laboratory strain Escherichia coli K-12 JM83 in order to determine the location of genes involved in production of polysaccharides in ...

Surface Polysaccharide Extraction and Quantification

open access: yesBio-Protocol, 2013
Gram-negative bacterial cells possess two membranes - the inner cytoplasmic membrane and the outer membrane. The two membranes are distinct in their composition; the inner membrane is composed of a phospholipid bilayer, whereas the outer membrane (OM) is

The digestion of yeast cell wall polysaccharides in veal calves [PDF]

open access: yes, 1976
1. The digestibility of the cell wall polysaccharides of an alkane-grown yeast in different parts of the digestive tract of two veal calves fitted with re-entrant cannulas at the end of the ileum was studied by replacing part of the skim-milk powder of ...

Masking the Pathogen: Evolutionary Strategies of Fungi and Their Bacterial Counterparts

open access: yesJournal of Fungi, 2015
Pathogens reduce immune recognition of their cell surfaces using a variety of inert structural polysaccharides. For example, capsular polysaccharides play critical roles in microbial survival strategies.

Bacterial capsular polysaccharides with antibiofilm activity share common biophysical and electrokinetic properties

open access: yesNature Communications, 2023
Bacterial biofilms are surface-attached communities that are difficult to eradicate due to a high tolerance to antimicrobial agents. The use of non-biocidal surface-active compounds to prevent the initial adhesion and aggregation of bacterial pathogens ...

Microphytobenthic extracellular polymeric substances (EPS) in intertidal sediments fuel both generalist and specialist EPS-degrading bacteria [PDF]

open access: yes, 2013
Microphytobenthic biofilms contain high concentrations of carbohydrate-rich extracellular polymeric substances (EPS) that are important in sediment carbon cycling.

Bacterial polysaccharide synthesis and export [PDF]

open access: yesCurrent Opinion in Structural Biology, 2016
All domains of life make carbohydrate polymers and by anchoring them to lipid molecules they can decorate the outside of the cell. Polysaccharides are linked to proteins by glycosylation, a process found in both bacteria and in higher organisms. Bacteria do have other distinct uses for carbohydrate polymers; in gram-negative bacteria glycolipids form ...
