xylitol is the first rare sugar that has global market due to having beneficial health properties and being an alternative to current conventional sweeteners. biotechnological production of xylitol by candida tropicalis dsm 7524 as an alternative to chemical method for the fermentation of xylose to xylitol was studied. banana peel was used as a substrate for xylitol production. hydrolysate was ...

OBJECTIVE The present study analyzed xylitol concentrations in artificial saliva over time after application of varnishes containing 10% and 20% xylitol. MATERIAL AND METHODS Fifteen bovine enamel specimens (8x4 mm) were randomly allocated to 3 groups (n=5/group), according to the type of varnish used: 10% xylitol, 20% xylitol and no xylitol (control). After varnish application (4 mg), specim...

OBJECTIVE To compare the immediate effect of xylitol chewing gum and xylitol mouth rinse on mutans streptococci (MS) levels in the saliva of adults with systemic sclerosis (SSc). METHODS Thirteen female adults with SSc were assigned randomly to either the xylitol chewing gum or xylitol mouth rinse groups. Participants in the chewing gum group were given 2 pellets (2.12g) of commercial xylitol...

The expulsion mechanism of xylitol 5-phosphate in Streptococcus mutans ATCC 25175 was studied using resting cells incubated in the presence of 14C-xylitol. The expulsion appeared to be a two-step process: xylitol 5-phosphate was first hydrolyzed to xylitol and inorganic phosphate, and the xylitol was subsequently expelled from the cells. The dephosphorylation step appeared to be energy-requirin...

  Objective: Although the most useful method to reduce mechanical dental plaque is brushing and flossing, but due to the lack of adequate effectiveness achieved by these methods, the use of other methods such as replacing sweeteners, including Xylitol and Sorbitol with sucrose in products such as chewing gums have come into the focus of attention. This research was done aimed at examine the eff...

This study evaluated the in vitro effects of four natural substances on the biomass of bacterial biofilms to assess their potential use as root canal irrigants. The following substances and their combinations were tested: 0.2% farnesol; 5% xylitol; 20% xylitol; 0.2% farnesol and 5% xylitol; 0.2% farnesol, 5% xylitol, and 0.1% lactoferrin; 5% xylitol and 0.1% lactoferrin; and 20 mM salicylic aci...

The authors declare no conflict of interest. The caries-controlling or preventing effect of xylitol is more than just excluding fermentable sugars from the diet. This review aims to discuss the specific effects of xylitol which could have contributed to the results of the caries trials. Xylitol promotes mineralization by increasing the flow of saliva, an effect it has in common with all sweeten...

Xylitol is a five-carbon sugar alcohol, a natural carbohydrate which occurs freely in certain plant parts (for example, in fruits, and also in products made of them) and in the metabolism of humans (1). Xylitol has been known to organic chemistry at least from the 1890's. German and French researchers were obviously the first ones who made xylitol chemically more than 100 years ago. This reacti...

BACKGROUND Xylitol is a 5-carbon sugar that can lower the airway surface salt concentration, thus enhancing innate immunity. We tested the safety and tolerability of aerosolized iso-osmotic xylitol in mice and human volunteers. METHODS This was a prospective cohort study of C57Bl/6 mice in an animal laboratory and healthy human volunteers at the clinical research center of a university hospit...
