Effects of different carbon sources on trichothecene production and Tri gene expression by Fusarium graminearum in liquid culture.
FEMS Microbiol. Lett. 285(2) , 212-9, (2008) Fusarium head blight caused by Fusarium graminearum is a disease of cereal crops that not only reduces crop yield and quality but also results in contamination with trichothecenes such as nivalenol and deoxynivalenol (DON). To analyze the trichothecene induct... |

Synthesis and structural analysis of five novel oligosaccharides prepared by glucosyltransfer from beta-D-glucose 1-phosphate to isokestose and nystose using Thermoanaerobacter brockii kojibiose phosphorylase.
Carbohydr. Res. 338(9) , 879-85, (2003) Five novel oligosaccharides (tetra-, penta- and hexa-saccharides) were synthesized by glucosyltransfer from beta-D-glucose 1-phosphate to isokestose (O-beta-D-fructofuranosyl-(2-->1)-O-beta-D-fructofuranosyl-(2-->1)-alpha-D-glucopyranoside) or nystose (O-beta... |

The chromatographic analysis of oligosaccharides and preparation of 1-kestose and nystose in yacon.
Int. J. Food Sci. Nutr. 63(3) , 338-42, (2012) The thin-layer chromatographic analysis of the crude oligosaccharides extracted from yacon revealed the presence of glucose, fructose, sucrose, 1-kestose and nystose. The qualitative and quantitative analysis was carried out on oligosaccharides by high pressu... |

Various non-digestible saccharides increase intracellular calcium ion concentration in rat small-intestinal enterocytes.
Br. J. Nutr. 92(5) , 751-5, (2004) We have previously shown that non-digestible saccharides (NDS) stimulate intestinal Ca absorption via tight junctions. However, the cellular mechanisms activated by the NDS are not yet known. We investigated the effects of four NDS, difructose anhydride (DFA)... |
