“The suppressive effect of D-xylose on the increase of blood glucose after sucrose loading was 2.4 times less than that of L-arabinose , probably due to intestinal absorption of the former.”

“The absorption of xylose is inhibited by the presence in the perfusate of any of the following substances (listed in decreasing order of their inhibitory ability): phlorizin > glucose > 3-0-methylglucose > fructose > 3-0-methyl-fructose > xylitol > arabinose.”

“Transcriptome sequencing (RNA-Seq) confirmed that arabinose addition to cells actively growing on xylose resulted in increased phosphoketolase (CA_C1343) mRNA levels, providing additional evidence that arabinose induces this metabolic switch.”
“In addition, we found that repression is reciprocal, where both L-arabinose and D-xylose also repress the lactose gene expression, albeit to a lesser extent and also through a mechanism involving cAMP.”

“In the present study, we found that d-xylose also represses the expression of the l-arabinose metabolic genes, leading to mixed populations of cells capable of utilizing l-arabinose and d-xylose.”
“Recent studies found that l-arabinose also represses the expression of the d-xylose metabolic genes.”
“We also found that d-xylose inhibited the expression of the l-arabinose metabolic genes and that this repression was due to XylR. These results demonstrate that a strict hierarchy does not exist between l-arabinose and d-xylose as previously thought.”
“Simultaneous feeding of xylose and arabinose revealed an unexpected hierarchy among the pentose sugars, with arabinose utilized preferentially over xylose.”
“On the contrary the enzymatic release of xylose was significantly correlated to the total release of arabinose , indicating that the degree of arabinosyl-substitutions on the xylan backbone is an essential parameter for enzymatic hydrolysis of corn bran arabinoxylan.”
