A Repeating Sulfated Galactan Motif Resuscitates Dormant Micrococcus luteus Bacteria [PDF]

Applied and Environmental Microbiology, 2018
ABSTRACT Only a small fraction of bacteria can autonomously initiate growth on agar plates. Nongrowing bacteria typically enter a metabolically inactive dormant state and require specific chemical trigger factors or signals to exit this state and to resume growth.

Recent Progressions in Applications of Bioactive Polysaccharides in Food and Health Sciences: A Comprehensive Review. [PDF]

Food Sci Nutr
Polysaccharides play a pivotal role in the development of safe and healthy foods. They ameliorate fatigue, preserve the microflora of the gastrointestinal tract, and provide health for the gut in living organisms. These biopolymers are applied for the fabrication of breakthrough drug delivery systems and potential platforms in regenerative medicine ...

Structure, biology, evolution, and medical importance of sulfated fucans and galactans [PDF]

Glycobiology, 2008
Sulfated fucans and galactans are strongly anionic polysaccharides found in marine organisms. Their structures vary among species, but their major features are conserved among phyla. Sulfated fucans are found in marine brown algae and echinoderms, whereas sulfated galactans occur in red and green algae, marine angiosperms, tunicates (ascidians), and ...

Purification, Cloning, Characterization and Essential Amino Acid Residues Analysis of a New iota-Carrageenase from Cellulophaga sp QY3 [PDF]

, 2013
ι-Carrageenases belong to family 82 of glycoside hydrolases that degrade sulfated galactans in the red algae known as ι-carrageenans. The catalytic mechanism and some substrate-binding residues of family GH82 have been studied but the substrate ...

Natural Products as Source of Potential Dengue Antivirals [PDF]

, 2014
Dengue is a neglected disease responsible for 22,000 deaths each year in areas where it is endemic. To date, there is no clinically approved dengue vaccine or antiviral for human beings, even though there have been great efforts to accomplish these goals.

Chemical characterization and antioxidant activity of sulfated polysaccharide from the red seaweed Gracilaria birdiae [PDF]

, 2012
Hydrocolloids from seaweeds have interesting functional properties, such as antioxidant activity and gelling ability. A polysaccharide was isolated by aqueous extraction at 90 C from the red seaweed Gracilaria birdiae (Gb), with a yield of 27.2% of the ...
