The pneumococcal serotype 14 polysaccharide was produced in Lactococcus lactis by coexpressing pneumococcal polysaccharide type 14-specific genes (cpsFGHIJKL(14)) with the lactococcal regulatory and priming glucosyltransferase-encoding genes specific for B40 polysaccharide (epsABCD(B40)). The polysaccharide produced by Lactococcus was secreted in the medium, simplifying downstream processing an...

1. The meningococcus polysaccharide reacts with a broad precipitable carbohydrate antibody in common with those of B. anthracis, B. subtilis, B. proteus and B. mesentericus. 2. The anthrax and proteus polysaccharides are specific in the higher dilutions of serum. 3. Antianthrax serum contains two different polysaccharide precipitable antibodies, one specific and the other non-specific. 4. Agglu...

In the present study ethanol and water extracts of 15 seaweeds, Dictyota dichotoma var. velutricata, Dictyota indica, Iyengaria stellata, Padina pavonia, Sargassum swartzii, Sargassum variegatum, Stoechospermum marginatum, Stokeyia indica, Jolyna laminarioides, Caulerpa taxifolia, Halimeda tuna, Ulva fasciata, Ulva lactuca, Solieria robusta, and ...

The ability of pea protein isolates (PPI) to form complex coacervates with tragacanth gum was investigated. coacervate formation structurally compared three other PPI-polysaccharide interaction models: arabic and sodium alginate (known PPI) tara gum, a galactomannan. effects the pH protein/polysaccharide ratio were mainly investigated using turbidity zeta potential measurements. Regarding solub...

BACKGROUND The efficacy of protein-conjugated pneumococcal polysaccharide vaccines has been well characterized for children. The level of protection conferred by unconjugated polysaccharide vaccines remains less clear, particularly for elderly individuals who have had prior antigenic experience through immunization with unconjugated polysaccharide vaccines or natural exposure to Streptococcus p...

streptococcus iniae is a major cause of serious bacterial infections in both fish and human beings. capsular polysaccharide (cps) of s. iniae is vital to evade phagocytic clearance of the host and serves as an important protective antigen of s. iniae infection in aquatic animals. the cpsdgene was determined to be highly conservative in capsule polysaccharide operon. prokaryotic expression of th...

our previous study revealed that the antioxidant activity of polysaccharide (coded as fgfp) extracted from grifola frondosa by enzymolysis treatment was significantly superior than that (coded as gfp) extracted by boiling-water. in this study, one purified polysaccharide fractions (coded as fgfp-11) was obtained from fgfp by purified using deae-52 column and sephacryl s-500hr column. results in...

biopolymers are environmental friendly sources as renewable and sustainable substituents for petroleum-based polymers. application of these polymers is common in variety of industries including papermaking. herbalexudate gums have been used in papermaking industry for decades, especially paper recycling. in this study, gum polysaccharide exudates from baridje plant  (ferula gummosa) extracted a...

A simple capillary electrophoretic method based on 1-phenyl-3-methyl-5-pyrazolon (PMP) derivatization has been developed for simultaneous separation and determination of nine aldoses (xylose, arabinose, glucose, rhamnose, fucose, galactose, mannose, glucuronic acid and galacturonic acid). The separation of PMP-labeled monosaccharide derivatives was carried out in uncoated capillary (48.5 cm x 7...

A method has been described whereby tuberculin P P D is linked to formalinized erythrocytes by a coupling agent, tetrazotized benzidine (1). These antigen-coated erythrocytes are agglutinated by ant ibody to PPD. I t was observed that P P D could inhibit the hemagglutination more effectively than could polysaccharide I. I t appears, therefore, tha t the ant ibody concerned is directed toward th...
