Nitrogen sorption as a tool for the characterisation of polysaccharide aerogels [PDF]
, 2011 Supercritically dried aerogels of several polysaccharides (chitin, chitosan, alginate, alginic acid, k- carrageenan, and agar) have been characterised by physisorption ofN2. Surface areas as high as 570m2 g−1 have been measured.

In vitro modulation of the human gut bacterial community by crude polysaccharides from cultivated mushrooms Lentinus polychrous and Lentinus squarrosulus [PDF]
PeerJBackground Edible mushroom polysaccharides are recognized as prebiotics that influence gut microbiota composition and host health. However, the effects of the polysaccharides from Lentinus squarrosulus and Lentinus polychrous on the human gut bacterial ...

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

Surface Polysaccharide Extraction and Quantification
Bio-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

Bacterial polysaccharide synthesis and export [PDF]
Current 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 ...

Masking the Pathogen: Evolutionary Strategies of Fungi and Their Bacterial Counterparts
Journal 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 glycobiology: rhamnose-containing cell wall polysaccharides in Gram-positive bacteria.
, 2016 The composition of the Gram-positive cell wall is typically described as containing peptidoglycan, proteins and essential secondary cell wall structures called teichoic acids, which comprise approximately half of the cell wall mass.
