Extracellular polysaccharides of Penicillium vermiculatum.
Extracellular Polysaccharide, Isolation, Characterization Extracellular polysaccharide mixture that forms a viscous mucilate in the fermentation medium during industrial cultivation of Penicillium vermiculatum was isolated by ethanol precipitation and its structural characteristics were investigated by a combination of physicochemical methods. The mixture contained two structurally different po...
متن کاملOLIgo Mass Profiling (OLIMP) of Extracellular Polysaccharides
The direct contact of cells to the environment is mediated in many organisms by an extracellular matrix. One common aspect of extracellular matrices is that they contain complex sugar moieties in form of glycoproteins, proteoglycans, and/or polysaccharides. Examples include the extracellular matrix of humans and animal cells consisting mainly of fibrillar proteins and proteoglycans or the polys...
متن کاملMicrobial Production of Extracellular Polysaccharides from Biomass
The interest in polysaccharides has increased considerably in recent years, as they are candidates for many commercial applications in different industrial sectors like food, petroleum, and pharmaceuticals. Because of their costly production processes, industrial microbial polysaccharides like xanthan, dextran, curdlan, gellan, and pullulan constitute only a minor fraction of the current polyme...
متن کاملBacterial extracellular polysaccharides involved in biofilm formation.
Extracellular polymeric substances (EPS) produced by microorganisms are a complex mixture of biopolymers primarily consisting of polysaccharides, as well as proteins, nucleic acids, lipids and humic substances. EPS make up the intercellular space of microbial aggregates and form the structure and architecture of the biofilm matrix. The key functions of EPS comprise the mediation of the initial ...
متن کاملIron oxyhydroxide mineralization on microbial extracellular polysaccharides
Iron biominerals can form in neutral pH microaerophilic environments where microbes both catalyze iron oxidation and create polymers that localize mineral precipitation. In order to classify the microbial polymers that influence FeOOH mineralogy, we studied the organic and mineral components of biominerals using scanning transmission X-ray microscopy (STXM), micro X-ray fluorescence (lXRF) micr...
