xylose

 [zi´lōs]
a pentose found in mucopolysaccharides of connective tissue, sometimes the urine, and vegetable gum. d-Xylose is used in a diagnostic test of intestinal absorption (see malabsorption syndrome).

xy·lose (Xy, Xyl),

(zī'lōs),
An aldopentose, isomeric with ribose, obtained by fermentation or hydrolysis of naturally occurring carbohydrate substances, for example, in wood fiber. An important dietary component for herbivores. The d-isomer is also known as wood or beechwood sugar.

xylose

/xy·lose/ (zi´lōs) a pentose found in plants in the form of xylans; it is used in a diagnostic test of intestinal absorption.

xylose

(zī′lōs′)
n.
A crystalline monosaccharide, C5H10O5, that is a component of most hemicelluloses in plants. Also called wood sugar.

xylose

[zī′lōs]
an aldopentose sugar produced by hydrolyzing straw and corn cobs. It is incompletely absorbed when taken by mouth and is used in diagnostic studies of the digestive tract.

xy·lose

(zī'lōs)
An aldopentose, isomeric with ribose, obtained by fermentation or hydrolysis of carbohydrate.

xylose

a PENTOSE SUGAR that is present in plant cell walls. Formula: C5 H10 O5.

xy·lose

(zī'lōs)
An aldopentose, isomeric with ribose, obtained by fermentation or hydrolysis of carbohydrate.

xylose (zī´lōs´),

n wood or beechwood sugar; an aldopentose, isomeric with ribose, obtained by fermentation or hydrolysis of naturally occurring carbohydrate substances such as wood fiber.

xylose

a pentose occurring in mucopolysaccharides of connective tissue and sometimes in the urine; also obtained from vegetable gum.

xylose absorption test, d-xylose absorption test
d-xylose absorbed primarily in the duodenum and cranial jejunum; after oral administration, urine or plasma determination at timed intervals can be used as an indication of intestinal absorption.

thermophilum was determined in growth medium containing xylan, xylose or glucose as carbon source (Table-1).
According to Figure 2A, there was a variation in the concentrations of glucose, xylose, arabinose and xylitol production during the 120 h of fermentation.
Although most of the phenotypic characteristics of the isolates were similar as claimed by [36], some isolates showed, however, variation in some of the biochemical tests particularly in the utilization of sugars which included mannitol, rhamnose, xylose, inositol.

However, Hector and his colleagues isolated the XI enzyme from several different rumen and intestinal bacteria and used them to engineer yeast strains that were able to ferment xylose into ethanol.
In this work, we have developed a novel co-culture system for the efficient and simultaneous conversion of mixed glucose and xylose to ethanol by Saccharomyces cerevisiae and Scheffersomyces stipitis.
Xylose is incorporated into the medium, since it is fermented by practically all enterics except for the Shigellae; this property enables the differentiation of Shigella species.
Carbon sources such as glucose, maltose, lactose, arabinose, glucose, galactose, sucrose, fructose, mannose, and xylose were used in 1% (w/v) to check the effect of these supplements on enzyme production.
coli, the isolated bacteria were subjected to the secondary screening and so all were tested for motility, sorbitol and xylose fermentation.
The researchers found that several sugars also give protective benefit but the sugar from RNA, ribose, is more effective than glucose or even xylose, a sugar remarkably similar to ribose, except its components are arranged differently.
These features include nonmotility, inability to ferment xylose and lactose, and inability to produce [beta]-D-glucuronidase.
