Capsules are long-chain carbohydrate polymers that envelop the surfaces of many bacteria, protecting them from host immune responses. Capsule biosynthesis enzymes are potential drug targets and valuable biotechnological tools for generating vaccine antigens. Despite their importance, it remains unknown how ...
Bacterial biofilms are a group or cluster of bacteria that are attached to natural or synthetic surfaces and grow embedded in a self-produced polymeric matrix that is composed mainly of exopolysaccharides (EPSs), proteins, and eDNA. From: Bioengineered Nanomaterials for Wound Healing and Infection ...
Bacteria exopolysaccharides (EPSs) are highly viscous carbohydrate polymers of different chemical composition that are secreted by bacteria and form either a closely attached layer (capsule) surrounding the bacterial cell or a loosely associated extracellular slime. EPSs have multiple functions, namely, pr...
Bacterial cellulose produced by few but specific microbial genera is an extremely pure natural exopolysaccharide. Besides providing adhesive properties and a competitive advantage to the cellulose over-producer, bacterial cellulose confers UV protection, ensures maintenance of an aerobic environment, retains m...

N. meningitidisa Gram-negative bacterial pathogen, is responsible for causing meningitis and sepsis, particularly affecting children and young adults123. This bacterium is categorized into five pathogenic serogroups based on the composition of its bacterial capsule: A, B, C, Y, and W135. Polysacchar...
1. Introduction High molecular weight polysaccharides are central constituents of the cell wall and extracellular matrix for all domains of life [1]. Specifically, in bacteria, they are the inte- grative part of the cell membranes (lipopolysaccharide/LPS), capsule (capsular polysac- cha...
2.1Properties of bacteria-derived carbon and the calcination process Bacteria are composed of various structural elements, including a secreted capsule, cell wall, cell membrane, cytoplasm, and a circular chromosome, which together form a hierarchical microcapsule structure. The cytoplasm contains water an...
The lectins can be either in the form of fimbrial structure, capsule, or as an outer membrane component in gram-negative bacteria. The adhesin-lectin binds to complementary sugars presented in glycoproteins and/or glycolipids on animal cell surface. Methods have been developed for the detection ...
pneumoniae serotype 14 capsule (CPS14). The general strat- egy for the production of geOMV is represented in Fig. 1. In principle, our platform can be applied to any surface glycan, such as O antigens, capsules, exopolysaccharides, or glycans present in N- and O-glycoproteins. The...
