Examples of "xylose" in Sentences
- Xylans are polymers of xylose and are constituents of plant cell walls.
- S. cerevisiae strains to convert five-carbon sugars such as xylose into ethanol.
- Thus a-xylose were the substrates for the 2R-aldose enzymes in their production of fructose
- What, on earth, compelled anyone to use xylose isomerase and oligosaccharides in the first place?
- Step 2: Enzymes A mix of cellulase enzymes is then added to convert the cellulose and hemicellulose molecules into the simple sugars glucose and xylose.
- As I said in my original post, it is based on new genetically modified yeasts capable of converting xylose sugar to ethanol alongside the traditional glucose fermentation.
- The product is manipulated, using a process that includes alpha-amylase, oligosaccharides, and xylose isomerase, into a syrup that is anywhere from 90% fructose/10% glucose to 42% fructose/58% glucose.
- Then there are two complicated steps: first, introducing enzymes, called cellulases, to break the cellulose down into glucose and xylose; and second, using yeast and other microorganisms to ferment those sugars into ethanol.
- Xylitol: A sugar alcohol, derived from xylan a complex sugar chain, sort of like cellulose, which is found in corncobs, straw, almond shells, and birch bark which is then broken down into individual units of a simple sugar, called xylose, which is then hydrogenated to make xylitol.
- The latest cellulose ethanol processes use recently identified enzymes to break down the biomass to separate the cellulose, hemicellulose and lignin cheaply, and new genetically modified yeasts which can ferment the C5 xylose sugar from hemicellulose as well as, and at the same time as, the normal C6 fermentation from cellulose.
