Objective: To determine the level of biofilm formation S. mutans after being exposed to 5% sucrose, 8% lactose, or 1% xylitol. Material and Methods: This research was a laboratory-based experimental study with post-test only control group design. grown in test tubes containing tryptose soy broth (TSB) medium supplemented glucose. They were incubated at 37° C for 24 hours grow biofilms. The cult...

Klewicka E., Klewicki R. (2009): In vitro fermentation of galactosyl derivatives of polyols by Lactobacillus strains. Czech J. Food Sci., 27: 65–70. Probiotic lactic acid bacteria belonging to the species Lactobacillus casei, Lb. paracasei, and Lb. acidophilus were cultivated in the presence of galactosyl derivatives of erythritol, xylitol, and sorbitol, as well as the polyols themselves: eryth...

Forty-six patients with liver cirrhosis were classified into three groups according to glucose tolerance test and the presence or absence of diabetic state. The results of xylitol tolerance test, galactose tolerance test, BSP retention, ICG disappearance rate and other routine liver function tests were compared between these three groups. The results show that liver cirrhosis in patients with o...

Pachysolen tannophilils is a yeast capable of fermenting xylose to ethanol. I,Z This organism is of interest due to its potential for converting the xylose found in agricultural and forestry residues to ethanol. Hemicellulosic sugars (i.e., xylose) are relatively abundant in certain plant residues and can be isolated with relative ease (for review, see ref. 3). The assumed pathway of xylose uti...

Xylose-to-xylitol bioconversion by Ca-alginate entrapped Candida guilliermondii cells in sugarcane bagasse hemicellulosic hydrolysate was carried out in erlenmeyer flasks using the repeated-batch mode of fermentation. The hydrolysate was supplemented or not with ammonium sulfate and/or rice bran extract at the beginning of each repeated batch. Altogether, six sets of three repeated-batches were...

This study evaluated, in vitro, the antimicrobial activity and the anti-adherent property of xylitol (0.5, 2.5 and 5.0%, w/v) on two Pseudomonas aeruginosa strains (ATCC 9027 and clinical). The assay of antimicrobial activity was performed to determine a minimum inhibitory concentration (MIC) and the adhesion test was performed, by which the parameters regarding, growth in the culture medium, n...

Remineralization of minor enamel defects is a normal physiological process that is well known to clinicians and researchers in dentistry and oral biology. This process can be facilitated by various dietary and oral hygiene procedures and may also concern dentin caries lesions. Dental caries is reversible if detected and treated sufficiently early. Habitual use of xylitol, a sugar alcohol of the...

In this paper we present a fast model system for monitoring the recrystallization of quench-cooled amorphous xylitol using Raman spectroscopy and wide-angle X-ray scattering. The use of these two methods enables comparison between surface and bulk crystallization. Non-ordered mesoporous silica micro-particles were added to the system in order to alter the rate of crystallization of the amorphou...

Nitric acid (HNO₃)-treated carbon fiber (CF) rich in hydrophilic groups was applied as a cell-immobilized carrier for xylitol fermentation. Using scanning electron microscopy, we characterized the morphology of the HNO₃-treated CF. Additionally, we evaluated the immobilized efficiency (IE) of Candida tropicalis and xylitol fermentation yield by investigating the surface properties of nitric aci...

A study was designed to determine the safety of a drinking water additive that reduces plaque and calculus in dogs, and contains xylitol as an active ingredient. The randomized, double-blind, placebo-controlled study was performed in 15 crossbred dogs that were randomly divided into three groups and had their drinking water treated for 14 days with either: i) a commercial health care product (B...
