Recent advances on applications and biotechnological production of d-psicose

Applied Microbiology and Biotechnology, 2012
D-Psicose is a hexoketose monosaccharide sweetener, which is a C-3 epimer of D-fructose and is rarely found in nature. It has 70 % relative sweetness but 0.3 % energy of sucrose, and is suggested as an ideal sucrose substitute for food products. It shows important physiological functions, such as blood glucose suppressive effect, reactive oxygen ...

Synthesis and stereochemistry of some derivatives of d-psicose

Carbohydrate Research, 1979
Abstract A number of derivatives of the ketohexose d -psicose have been synthesized, comprising examples of acetals, esters, ethers, and glycosides. Among them are precursors of 1-,3-,5-, and 6-mono- O -methyl- d -psicose, including 3- O -methyl-β- d -psicopyranose 4,5-carbonate, the first crystalline representative of the reducing form of the ...

A d-psicose 3-epimerase with neutral pH optimum from Clostridium bolteae for d-psicose production: cloning, expression, purification, and characterization

Applied Microbiology and Biotechnology, 2013
D-Tagatose 3-epimerase family enzymes can efficiently catalyze the epimerization of free keto-sugars, which could be used for D-psicose production from D-fructose. In previous studies, all optimum pH values of these enzymes were found to be alkaline. In this study, a D-psicose 3-epimerase (DPEase) with neutral pH optimum from Clostridium bolteae (ATCC ...

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 ...

Efficient conversion of allitol to d-psicose by Bacillus pallidus Y25

Journal of Bioscience and Bioengineering, 2007
An efficient method for conversion of allitol to D-psicose was achieved by a resting cell reaction of Bacillus pallidus Y25 for the first time. Notably, it was possible to produce D-allose and D-altrose from allitol directly via D-psicose by prolonging the reaction time. This method was applied for the preparation of D-psicose using the extract of Itea

Chitosan Productivity Enhancement in Rhizopus oryzae YPF-61A by D-Psicose

Journal of Bioscience and Bioengineering, 2003
The effect of the rare sugar D-psicose on chitosan production by Rhizopus oryzae was studied. The fungus was not able to utilize D-psicose as a sole source of carbon, either for germination of the spores or for growth of the vegetative cells. In a medium containing a low amount of D-glucose, however, D-psicose supplementation between 5 and 12 g/l ...

Crystal data of branched-chain derivatives of D-psicose

Journal of Applied Crystallography, 1981
Crystal data are reported for six derivatives of 1,2-O-isopropylidene-3-C-(pyridin-2-yl)-β-D-psicopyranose, C14H19NO6, previously studied in solution by NMR spectroscopy. Molecules that differ only by the replacement of H by CH3 on one non-ring oxygen atom, converting an alcohol to an ether molecule, show no similarity in cell dimensions, and have ...
