Depolymerases for Bacterial Exopolysaccharides obtained from Phage-Infected Bacteria

Some Properties of DNA from Phage-Infected Bacteria

Replicating T5 or lambda phage DNA has been labeled by adding tritiated thymidine for short periods to cultures of phage-infected Escherichia coli before isolation of intracellular DNA. Two procedures are described for separating T5 replicating DNA from DNA of intracellular phage particles. Both T5 and lambda replicating DNA had the same bouyant density in cesium chloride as DNA from phage part...

Bioprospecting for Exopolysaccharides from Deep-Sea Hydrothermal Vent Bacteria: Relationship between Bacterial Diversity and Chemical Diversity

Many bacteria biosynthesize structurally diverse exopolysaccharides (EPS) and excrete them into their surrounding environment. The EPS functional features have found many applications in industries such as cosmetics and pharmaceutics. In particular, some EPS produced by marine bacteria are composed of uronic acids, neutral sugars, and N-acetylhexosamines, and may also bear some functional sulfa...

Biological functions of exopolysaccharides from probiotic bacteria

Probiotic bacteria have the ability to produce exocellular polymers called exopolysaccharides (EPS). It has been suggested that the health benefit of probiotic bacteria can be attributed to the production of EPS. However, the composition, structure and biological functions of EPS may vary depending on the type of microorganism and environmental conditions. Some data suggest that EPS production ...

Bacterial Exopolysaccharides: Functionality and Prospects

Diverse structural, functional and valuable polysaccharides are synthesized by bacteria of all taxa and secreted into the external environment. These polysaccharides are referred to as exopolysaccharides and they may either be homopolymeric or heteropolymeric in composition and of diverse high molecular weights (10 to 1000 kDa). The material properties of exopolysaccharides have revolutionized...
