The soluble specific substance of Pneumococcus Type I has been chemically isolated from the bacterial cells and from autolyzed cultures as an acetyl polysaccharide. So far as could be determined by the methods employed, the acetyl polysaccharide in highly purified form absorbs from Type I antipneumococcus serum all demonstrable type-specific precipitins, agglutinins and protective antibodies. M...

Introduction: Fruit polysaccharides, essential health factors in foods, are widely present in edible fruits. Several methods for isolation of polysaccharide are available. Microwave Assisted Extraction (MAE) method is extensively used for separation of polysaccharides. Only little information is available about Psidium guajava L. Fruit Polysaccharide (PFP) and its extraction methods. Objective:...

This review covers the literature concerning the modification of polysaccharides through controlled radical polymerizations (NMP, ATRP and RAFT). The different routes to well-defined polysaccharide-based macromolecules (block and graft copolymers) and graft-functionalized polysaccharide surfaces as well as the applications of these polysaccharide-based hybrids are extensively discussed.

Inflammation is a part of the non-specific immune response which occurs in reaction to any type of injury. Medicinal mushrooms have had application in various disorders including cancer, liver injuries, inflammation and diabetes. In the present study, the anti-inflammatory effects of the aqueous extracts of medicinal mushrooms (Fomes fomentarius, Ganoderma applanatum and T...

Extraction of high quality RNA is a critical step in molecular genetics studies. Hazelnut is one of the most important nuts plants in the world. The presence of the taxol and other taxanes in hazelnut plant necessitates explaining their biosynthesis pathway and identifying the candidate genes. Therefore, an easy and practical method is necessary for RNA extraction from hazelnuts. Hazelnut has h...

We describe a rapid and efficient method for producing the capsular polysaccharide of Streptococcus pneumoniae by fermentation on tryptic soy broth and purification of this compound by using immobilized soybean lectin as an affinity adsorbent. In principle, the same strategy can be used to produce purified capsular polysaccharides from other streptococcal serotypes by selecting the appropriate ...
