Rehmannia glutinosa (Gaertn.) DC. polysaccharide ameliorates hyperglycemia, hyperlipemia and vascular inflammation in streptozotocin-induced diabetic mice.
J. Ethnopharmacol. 164 , 229-38, (2015) Rehmannia glutinosa (Gaertn.) DC. (RG) has been widely used as traditional Chinese herbal medicine for treatment of diabetes and its complications. The polysaccharide fraction of RG has been proposed to possess hypoglycemic effect by intraperitoneal administr... |

An L-Fucose Operon in the Probiotic Lactobacillus rhamnosus GG Is Involved in Adaptation to Gastrointestinal Conditions.
Appl. Environ. Microbiol. 81 , 3880-8, (2015) L-Fucose is a sugar present in human secretions as part of human milk oligosaccharides, mucins, and other glycoconjugates in the intestinal epithelium. The genome of the probiotic Lactobacillus rhamnosus GG (LGG) carries a gene cluster encoding a putative L-f... |

Kinetic characterization of Aspergillus niger chitinase CfcI using a HPAEC-PAD method for native chitin oligosaccharides.
Carbohydr. Res. 407 , 73-8, (2015) The abundant polymer chitin can be degraded by chitinases (EC 3.2.1.14) and β-N-acetyl-hexosaminidases (EC 3.2.1.52) to oligosaccharides and N-acetyl-glucosamine (GlcNAc) monomers. Kinetic characterization of these enzymes requires product quantification by a... |

Isolation, structure, and surfactant properties of polysaccharides from Ulva lactuca L. from South China Sea.
Int. J. Biol. Macromol. 79 , 577-82, (2015) Two polysaccharides (ULP1 and ULP2) were isolated through ultrasonic-assisted extraction from green seaweed Ulva lactuca L. which was collected from the South China Sea. The highest yield of 17.57% was obtained under the conditions of 2% NaOH, 90 °C, material... |

Glycan complexity dictates microbial resource allocation in the large intestine.
Nat. Commun. 6 , 7481, (2015) The structure of the human gut microbiota is controlled primarily through the degradation of complex dietary carbohydrates, but the extent to which carbohydrate breakdown products are shared between members of the microbiota is unclear. We show here, using xy... |

Use of Commercial Dry Yeast Products Rich in Mannoproteins for White and Rosé Sparkling Wine Elaboration.
J. Agric. Food Chem. 63 , 5670-81, (2015) In sparkling wines, mannoproteins released during yeast autolysis largely affect their final quality. This process is very slow and may take several months. The aim of this work was to study the effect of several commercial dry yeast autolysates on the chemic... |

Affinity ligands for glycoprotein purification based on the multi-component Ugi reaction.
J. Chromatogr. B. Analyt. Technol. Biomed. Life Sci. 969 , 171-80, (2014) One challenge facing the purification of therapeutic glycoproteins by affinity chromatography is creating ligands specific for the glycan moiety. Affinity chromatography of glycoproteins is currently conducted with immobilized lectins or boronates, although b... |

Steam explosion distinctively enhances biomass enzymatic saccharification of cotton stalks by largely reducing cellulose polymerization degree in G. barbadense and G. hirsutum.
Bioresour. Technol. 181 , 224-30, (2015) In this study, steam explosion pretreatment was performed in cotton stalks, leading to 5-6 folds enhancements on biomass enzymatic saccharification distinctive in Gossypium barbadense and Gossypium hirsutum species. Sequential 1% H2SO4 pretreatment could furt... |
