Hemicellulose is a group of polysaccharides that can be found in the plant s cell wall that surrounds the cellulose, protein, lignin, and other materials that covalently bonded, hydrogen bonds, ionic bonds and interactions hydrophoby [35]. In plants, hemicellulose is a second polymer after cellulose that abundance in wood and cereals. It consists of approximately one-quarter to one-third of the plant material. This amount varies according to the type of plants, such as corn steins [28.0%], wheat straw [38.8%), rice straw [35.8%), and rye straw [36.9%). Hemicellulose serves as a supporter to cell wall and as an adhesive between single cells In plants [10]. 

Wheat and rye straws are considered to be lower in nutritional value than barley straw. However, the digestibility of most cereal straws can be markedly improved with alkali treatment (see below).
