Use of Aspergillus niger Extracts Obtained by Solid-State Fermentation

摘要: Abstract Agroindustrial wastes are both an environmental and economic problem that industries must strive to solve. However, these residues represent inexpensive alternative source for microbial growth biomass or enzyme production, mainly using solid-state fermentation (SSF). Corn cob, a worldwide by-product obtained from maize processing, has lignocellulosic structure made up of cellulose, hemicelluloses, lignin. Aspergillus niger is one the most frequently employed filamentous fungi in production enzymes by SSF. This fungal species can grow on corn cob produce xylanases, which catalyze hydrolysis xylan, heterogeneous polysaccharide consisting backbone chain β-1,4-linked β- d -xylopyranose units. Fungal xylanases have several applications paper manufacturing, animal feed, bread making, juice, wine industries. Xylanases also interesting xylooligosaccharides, used as functional food ingredients, xylose bioconversion into xylitol.
