Some Biological Properties of Pneumococcus Type 37 and the Chemistry of Its Capsular Polysaccharide

Pneumococcus Type 37, like pneumococcus Type 3, is characterized by the production of large mucoid colonies on the surface of solid media and by its very large capsule. It differs from the highly virulent pneumococcus Type 3 in that it is only slightly virulent for mice and rats and is isolated infrequently from man. A study of the behavior of pneumococcus Type 37 in systems comparable to those...

Chemistry and applications of polysaccharide solutions in strong electrolytes/dipolar aprotic solvents: an overview.

Biopolymers and their derivatives are being actively investigated as substitutes for petroleum-based polymers. This has generated an intense interest in investigating new solvents, in particular for cellulose, chitin/chitosan, and starch. This overview focuses on recent advances in the dissolution and derivatization of these polysaccharides in solutions of strong electrolytes in dipolar aprotic...

Polysaccharide Biosynthesis

Polysaccharide synthesis is discussed from the point of view of the sources of biological information that determine the structures and control the rates of synthesis of complex polysaccharides. It is concluded that three types of information contribute in important and different ways, namely enzyme specificity, primer substances, and the structure of the cytoplasmic membrane. Each of these fac...
