Xylose: absorption, fermentation, and post-absorptive metabolism in the pig [PDF]

Journal of Animal Science and Biotechnology, 2018
Xylose, as β-1,4-linked xylan, makes up much of the hemicellulose in cell walls of cereal carbohydrates fed to pigs. As inclusion of fibrous ingredients in swine diets continues to increase, supplementation of carbohydrases, such as xylanase, is of interest.

Feedbacks from the metabolic network to the genetic network reveal regulatory modules in E. coli and B. subtilis

, 2018
The genetic regulatory network (GRN) plays a key role in controlling the response of the cell to changes in the environment. Although the structure of GRNs has been the subject of many studies, their large scale structure in the light of feedbacks from ...

The methionine salvage pathway in Bacillus subtilis [PDF]

, 2002
BACKGROUND: Polyamine synthesis produces methylthioadenosine, which has to be disposed of. The cell recycles it into methionine through methylthioribose (MTR). Very little was known about MTR recycling for methionine salvage in Bacillus subtilis. RESULTS:

Engineering xylose metabolism in yeasts to produce biofuels and chemicals

Current Opinion in Biotechnology, 2021
Xylose is the second most abundant sugar in lignocellulosic biomass. Efficient and rapid xylose utilization is essential for the economic bioconversion of lignocellulosic biomass into value-added products. Building on previous pathway engineering efforts to enable xylose fermentation in Saccharomyces cerevisiae, recent work has focused on reprogramming

Regulation of Arabinose and Xylose Metabolism inEscherichia coli [PDF]

Applied and Environmental Microbiology, 2010
ABSTRACTBacteria such asEscherichia coliwill often consume one sugar at a time when fed multiple sugars, in a process known as carbon catabolite repression. The classic example involves glucose and lactose, whereE. coliwill first consume glucose, and only when it has consumed all of the glucose will it begin to consume lactose.

Engineering of a Xylose Metabolic Pathway in Corynebacterium glutamicum [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACT The aerobic microorganism Corynebacterium glutamicum was metabolically engineered to broaden its substrate utilization range to include the pentose sugar xylose, which is commonly found in agricultural residues and other lignocellulosic biomass.

Nicotine Reprograms Aging‐Related Metabolism and Protects Against Motor Decline in Mice

Advanced Science, EarlyView.
Long‐term oral nicotine intake protects against age‐related motor decline in mice without eliciting systemic toxicity. Integrated multi‐organ metabolomic profiling and longitudinal gut microbiota analyses reveal that nicotine induces coordinated remodeling of glycolipid and sphingolipid metabolism, enhances NAD⁺ bioavailability, and suppresses ceramide

The future of bioethanol [PDF]

, 2019
Yeasts have been domesticated by mankind before horses. After the mastering of alcoholic fermentation for centuries, yeasts have become the protagonist of one of the most important biotechnological industries worldwide: the production of bioethanol. This
