The presence of readily metabolizable carbon sources like glucose, cellobiose, xylobiose, or xylose represses the synthesis of xylanase enzymes for the utilization of certain carbon sources such as xylan or cellulose and the process is known as catabolite repression.
Xylan eliminates the need for lubricants and a wet release, and makes production faster.
In particular Coatresa work with Whitford Xylan [R] Coatings.
The experimental researches were performed on a test stand existing within the University "Eftimie Murgu", Resita, on whose gear a one, two and three layers of fluoro-polymerised Xylan 1052 were filled.
One that degrades xylan would be of interest because xylan forms the backbone of hemicellulose, a molecule that complicates production of cellulosic ethanol.
Xylan is widely distributed in plant cell walls and forms a main part of the hemicellulose fraction [1].
That's just what Whitford Plastics has achieved with its Xylan 1010 nonstick (low-friction) coating for a wide variety of garden tools.
THIS shimmering silver-coloured Xylan stir-fry wok has the style and taste to match the food cooked in it.
Production of polygalacturonase and pectinesterase was induced by pectin, sodium carboxymethyl cellulose, and xylan.
Summary: Among the fungi, the soft rot fungus Trichoderma has shown to be efficient producers of xylan degrading enzyme.
After exhaustive testing, Whitford's Xylan 1632 was proven to exceed all of the customer's requirements and was immediately approved for production.
