Carbohydrates for fermentation

Biomass accumulated by the photosynthetic fixation of carbon dioxide is the only renewable carbon source, and hence, the only renewable raw material for the chemical industry. Carbohydrates are the main constituents of biomass and occur as cell wall and storage carbohydrates, transportation carbohydrates and glycoconjugates. Cellulose, hemicelluloses and starch in particular as well as pectin, inulin and saccharose to a smaller extent are the most abundant carbohydrates. Glucose is the most important monosaccharide and monomer of polysaccharides in natural carbohydrates. Thus, it is the most abundant organic compound on earth. Production of pulp from wood cellulose, applications of starch for paper making as well as uses of glucose and saccharose for fermentation are the most important chemical and technical uses of carbohydrates. Carbohydrates used as fermentation feedstock are essential for the chemical industry. Their importance is steadily growing due to the increasing implementation of biotechnological processes.
