WebXylose and Arabinose. Xylose and arabinose is the major constituents of hemicellulose, large quantities of which are found in agricultural waste, such as rice straw, corncobs, and parts of hard wood. Zhang et al. have described an improved Z. mobilis strain capable of producing ethanol from xylose and arabinose ( Figure 1 ). WebBiochem/physiol Actions. L-Arabinose is the naturally occurring isomer and is a constituent of plant polysaccharides. Most bacteria contain an inducible arabinose operon that codes for a series of enzymes and transporters that allows L-arabinose to be used as the sole carbon source in microbial culture.
