Until recently the enzymatic degradation of recalcitrant polysaccharides such as cellulose and chitin was thought to be accomplished through enzyme systems comprised of exo- and endo-acting glycoside hydrolases (GHs). Speculations about additional activities, for example a decrystallizing factor, emerged in...
The cross-over between both research fields enables the creation of fascinating materials with advanced engineering properties, where the (poly)dopamine serves as a general platform for the functionalization of polysaccharides. In this review, the role of poly(dopamine) in modification of cellulose and...
Polysaccharides (pullulans) were purified from the cultures of two of the above fungi (Phaeoacremonium) and were shown to be nonselectively toxic to cuttings of grapevine and other plants (76). Symptoms on shoots and branches. Symptoms can start in spring with delayed and weak growth and end...
Because of their specific adaptations, biocrust organisms have considerable biotechnological potential with respect to e.g. enzymes, antioxidants, antimicrobials, biosurfactants, polysaccharides, and lipids7. Among eukaryotic algae, species of Bracteacoccus (Sphaeropleales, Chlorophyta) are common constituents...
a) List the polysaccharides found in cells or organisms. b) Explain their role in microorganisms. Explain why some proteins are made by nearly all cells. Give two examples. Describe the ways in which archaea are similar to eukaryotes.
Explain disaccharides with examples. Starch, cellulose, dextran, and glycogen are all polysaccharides. How are they similar? To what are their different properties due? What chemical property can be used to identify a lipid? Describe the structure and function of carbohydrates, lipids, proteins, and...
It is suggested indicating that the partial oxygen tension should be that rhizobial surface polysaccharides (exopoly- suitable for a nitrogenase activity. However, our saccharide, capsular polysaccharide or lipopolysac- cytological observations indicate that these bacteria charide) could suppress or help...

Considering the large functional diversity within GH43 family, with specificity for distinct polysaccharides or sugar moieties, the conformational routes and catalytic mechanisms of GH43 enzymes might further diverge. However, the rarity of Michaelis complex structures available for these enzymes hampers the...
Methods to measure the cristallinity of a probe of polysaccharides can be found in Frech, D, J. Jpn. Soc. Starch, 1972 19,8 and Zobel, H. F., Starch/Stärke 1988, 40, 1. The resulting distribution of the intensity in arbitrary units as a function of the scattering angle is integ...
