d-Allose and d-psicose reinforce the action of metronidazole on trichomonad

Parasitology Research, 2011
The effects of D-allose and D-psicose on Tritrichomonas foetus were examined. They were cultured in F-bouillon medium including glucose, but had never increased when glucose was substituted to those sugars. When cultured in a medium including a dose of ED(50) metronidazole and those sugars, trichomonad density was significantly less than that in a ...

d-Allose production from d-psicose using immobilized l-rhamnose isomerase

Journal of Fermentation and Bioengineering, 1998
Abstract d -Psicose was produced from d -fructose using an immobilized d -tagatose 3-epimerase ( d -TE), and used as a substrate for the production of d -allose by immobilized l -rhamnose isomerase ( l -RI). d -Allose was produced from d -ssicose by l -RI, which was constitutively produced by a mutant strain of Pseudomonas sp.

The synthesis of D-psicose derivatives using recent oxidative procedures

Journal of the Chemical Society C: Organic, 1967
The oxidation of authentic 1,2,:4,5-di-O-cyclohexylidene-D-fructopyranose and of 1,2:4,5-di-O-isopropylidene-D-fructopyranose with dimethyl sulphoxide–acetic anhydride yields 1,2:4,5-di-O-cyclohexylidene-D-erythro-hex-3-ulopyranose and 1,2:4,5-di-O-isopropylidene-D-erythro-hex-3-ulopyranose, respectively.

Antioxidant properties of custard pudding dessert containing rare hexose, d-psicose

Food Control, 2007
Abstract Custard pudding (CP) is a sweet dessert composed of nutritionally valuable egg, milk and sucrose. In the present study, d -psicose (Psi), a noncalorie rare hexose, was added into raw materials of custard pudding as a substitute for sucrose in order to develop a new functional dessert.

Production of d-talitol from d-psicose by Candida famata R28

Journal of Fermentation and Bioengineering, 1998
A halotolerant yeast strain R28 that can convert d-psicose to d-talitol was isolated from soy sauce mash and identified as Candida famata. The cells grown on l-sorbose were found to have the best conversion potential. C. famata R28 converted d-psicose to d-talitol at a faster rate in the presence of various carbohydrates such as erythritol, d-sorbitol,

Conversion of d-psicose to allitol by Enterobacter agglomerans strain 221e

Journal of Fermentation and Bioengineering, 1995
Abstract Enterobacter agglomerans strain 221e transformed d -psicose to allitol at a faster rate in the presence of d -glucose in the reaction mixture when the entrance of oxygen was restricted. Cells grown on glycerol were found to be suitable for the transformation reaction.

Diisopropylidene acetals of D-allose and D-ribo-hexulose (D-psicose)

Carbohydrate Research, 1970
Abstract Acetonation of D -allose in the presence of sulfuric acid gives 2,3:5,6-di- O -isopropylidene-β- D -allofuranose ( 4 ) in good yield. Oxidation of 4 with methyl sulfoxide and acetic anhydride gave 2,3:5,6-di- O -isopropylidene- D -allono-1,4-lactone (7). Compound 4 was also obtained from 1,2:5,6-di- O isopropylidene-α- D -allofuranose (

Bioconversion of D-psicose to D-tagatose and D-talitol by Mucoraceae fungi

Journal of Bioscience and Bioengineering, 2006
Rhizopus oryzae MYA-2483, which cannot utilize D-psicose as a sole source of carbon, converted D-psicose to two other compounds. These compounds were identified by NMR and IR as D-tagatose and D-talitol. In this study, we describe for the first time the bioconversion of D-psicose to D-tagatose. Various strains of Mucoraceae fungi, to which R.

Development of an amperometric flow analysis sensor for specific detection of d-psicose

Biosensors and Bioelectronics, 2008
The aim of this study was to develop a simple, rapid and highly sensitive sensor for measuring the rare sugar d-psicose. The proposed system adopts amperometric flow analysis and two consecutive enzyme reactions consisting of a reactor packed with d-tagatose 3-epimerase (DTE)-immobilized beads, which converts d-psicose to d-fructose, and a carbon-paste
