Inhibition By Toxic Compounds In The Hemicellulosic Hydrolysates On The Activity Of Xylose Reductase From Candida Tropicalis

Xylose reductase (XR) is an oxidoreductase having potential applications in the production of various specialty products, mainly xylitol. It is important to screen for compounds that can decrease XR activity and consequently can decrease xylitol production. We have identified the byproducts in...
