Xylitol, a naturally occurring sugar alcohol, can reduce AOM when given 5 times per day as a gum or syrup, but a more convenient dosing regimen is needed for widespread adoption. METHODS: We designed a pragmatic practice-based randomized controlled trial to determine if viscous xylitol solution ...
xylitol was found to be an excellent substitute for sugar in diabetic patients, and had a certain therapeutic effect, which attracted the attention of all countries in the world. Following the Soviet Union, Japan established xylitol plants in the 60 s; Finland and Italy also built plants in th...
In the subsequent step, xylulose conversion can be further streamlined through the overexpression of xylulokinase, EC 2.7.1.17 (XK) (the third enzyme in the xylose metabolism that converts xylulose to xylulose-5-phosphate). The C5 sugar, xylulose-5-phosphate, is the entry point to the ...
marxianus acquires resistance to various antifungal drugs, high temperatures, high osmolarity, acidity, and other stressors, through alterations in the composition and ratio of membrane sterols. By employing sterol engineering, the fermentation temperature of this unconventional thermotolerant K. marxianus ...
(b), in milligrams; r t = ratio of the area of the peak due to derivatised xylitol to the area of the peak due to the derivatised internal standard in the chromatogram obtained with reference solution (b); r v = ratio of the area of the peak due to derivatised xylitol to the area...
It is known that many yeast strains produce reductase enzymes that catalyse the reduction of sugars to corresponding sugar alcohols. Many yeasts, in particular Pichia, Candida, Hansenula and Kluyveromyces, are also capable of reducing xylose to xylitol as an initial step in their xylose metabolism....
Regardless, the constituent sugars of gellan gum are glucose, glucuronic acid and rhamnose in the molar ratio of about 2:1:1. These sugars are linked together to give a primary structure having a linear tetrasaccharide repeat unit.As stated, the gellan gum may be either high or low acyl ...
Fermentation characteristics of recombinant Saccharomyces cerevisiae containing a xylose reductase gene from Pichia stipitis were investigated in an attempt to convert xylose to xylitol, a natural five-carbon sugar alcohol used as a sweetener. Xylitol was produced with a maximum yield of 0.95 g g 1 ...
Xylitol has been widely used as a sweetening agent resembling sugar. For instance, xylitol may be used in confectionery, bakery products, cereals, desserts, jams, beverages, chocolate, chewing gums, ice-cream, and in various dietetic products. Xylitol has also been used in the production of ora...
The xylitol will normally be employed in a weight ratio to the hydrocolloid (for example, xanthan gum) in a range of from about 60:1 to about 2000:1, and preferably from about 500:1 to about 1500:1 in order to impart the desired cohesiveness to the final gum product. The chewing gu...
