✦ Synopsis

An exocellular polysaccharide produced by a clinical isolate of Proteus vulgaris (ATCC 49990) was shown by composition, methylation, periodate oxidation, and nuclear magnetic resonance analyses to be composed of repeating trisaccharide units containing n-galactose, 2-acetamido-2-deoxy-d-glucose and pyruvic acid (2: 1: l), and having the structure:

The homologus smooth lipopolysaccharide of the P. uulgaris strain was determined to have an 0-polysaccharide component having the same structure as the above extracellular polysaccharide.

The polysaccharide Zanflo from Erwiniu tahitica ATCC 217 11 (S-10) [ 1] is one of many being prepared for industrial applications. It is valuable because of its fermentation efficiency and product properties. These include better viscosity than xanthan gum and larger compatibility with dyes. We have

Bacterial polysaccharides constitute non-toxic, well-defined, natural polymers which have found many industrial applications. The polysaccharide with the code name S-156 from Klebsiellu pneumoniae ATCC 316 46 has good viscosity properties and is therefore of potential commercial interest. We have no

The cyanobacterium (blue-green alga) Anabaena sp. ATCC 33047 produces an exopolysaccharide (EPS) during the stationary growth phase in batch culture. Chemical analysis of EPS revealed a heteropolysaccharidic nature, with xylose, glucose, galactose, and mannose the main neutral sugars found. The infr
