More than ten â-glycosyltransferases are now recognized that have limited similarity to the amino acid sequence of cellulose synthase from Acetobacter xylinum. Using hydrophobic cluster analysis (HCA), we recently identified two domains and putative catalytic residues in the processive âglycosyltransferases. In this study, we have found expressed sequence tags (ESTs) from higher plants (Arabido...

Two families of aldols, obtained from the condensation of aromatic aldehydes with cyclohexanone or acetone (ten examples in each group), were analyzed by high-performance liquid chromatography in normal phase elution mode on three polysaccharide-based chiral stationary phases of the Lux series, namely, Lux Cellulose-2, Lux Cellulose-4 and Lux Amylose-2, which share the common feature of chlorin...

The metatranscriptomic recharacterization in the present study captured microbial enzymes at the unprecedented scale of 40,000 active genes belonged to 2,269 KEGG functions were identified. The novel information obtained herein revealed interesting patterns and provides an initial transcriptional insight into the thermophilic cellulose methanization process. Synergistic beta-sugar consumption b...

Every year, over 8 million tons of crustacean shells are discarded. However, there exists an opportunity for valorizing the chitin and calcium carbonate part composition shells. Our study revealed reduces self-aggregation effects. It was shown that crustacean-based nanofibers alone or added to cellulose offer unprecedented reductions in viscosity even after drying produce foams impossible cellu...

Cellulose is the major component of cell wall materials. A 300 bp specific fragment from the cDNA fragment was chosen to insert into vector pFGC1008 at forward and reverse orientations to construct the recombinant RNAi vector. Knockdown of BoiCesA caused "dwarf" phenotype with smaller leaves and a loss of the content of cellulose. Moreover, RT-PCR analysis confirmed that the expression of the R...

Enterobacterial animal pathogens exhibit aggregative multicellular behavior, which is manifested as pellicles on the culture surface and biofilms at the surface-liquid-air interface. Pellicle formation behavior requires production of extracellular polysaccharide, cellulose, and protein filaments, known as curli. Protein filaments analogous to curli are formed by many protein secretion systems, ...

Study provides an in-depth analysis of the structure-function relationship polysaccharide anticancer drug carriers and points out benefits potential drawbacks differences in glycosidic bonding, branching binding mode carriers. Cellulose, dextrin, dextran hyaluronic acid have been regioselectively oxidized to respective dicarboxylated derivatives, allowing them directly conjugate cisplatin, whil...

Abstract Composite nanoparticles (NPs) consisting of lignin and different polysaccharide (PS) derivatives were prepared. In this synergistic approach, the PS derivative acts as biocompatible matrix that forms spherical NPs while is a functional compound with therapeutic potential (e.g., antioxidative, antimicrobial, antiviral). Organosolv three (cellulose acetate/CA, cellulose acetate phthalate...

Abstract We investigated the effects of substrate (cellulose or starch) and different clay contents on production microbial extracellular polymeric substances (EPS) concomitant development stable soil aggregates. Soils were incubated with amounts montmorillonite (+ 0.1%, + 1%, 10%) both without two substrates contrasting quality (starch cellulose). Microbial respiration (CO 2 ), biomass carbon ...

Cell walls are barriers that impair colonization of host tissues, but also are important reservoirs of energy-rich sugars. Growing hyphae of necrotrophic fungal pathogens, such as Botrytis cinerea (Botrytis, henceforth), secrete enzymes that disassemble cell wall polysaccharides. In this work we describe the annotation of 275 putative secreted Carbohydrate-Active enZymes (CAZymes) identified in...
