【 摘 要 】

The "Green and Blue Technologies Strategies in HORIZON 2020" has increased the attention of scientific society on global utilization of renewable energy sources. Agricultural residues can be a valuable source of energy because of drastically growing human needs for food. The goal of this review is to show the current state of art on utilization of wheat straw as a substrate for ethanol production. The specifics of wheat straw composition and the chemical and thermodynamic properties of its components pre-determined the application of unit operations and engineering strategies for hydrolysis of the substrate and further its fermentation. Modeling of this two processes is crucially important for optimal overall process development and scale up. The authors gave much attention on main hydrolisis products as a glucose and xylose (C6 and C5 sugars, respectivelly) and on the specifics of their metabolization by ethanol producing microorganisms. The microbial physiology reacting on C6 and C5 sugars and mathematical aproaches describing these phenomena are discussing, as well.
