Abstract
Potential amylase enzymes have many industrial applications that are found in biological sources like animal, plants and microorganisms. Fungi and bacteria hold tremendous potential to produce the α-amylases using agriculture by-products under solid state fermentation (SSF). Agro-industrial residues such as rice bran, wheat bran, sugar cane bagasse, corn leaf, barley, orange peel, wheat straw, rice straw is abundant and cheapest carbon source. SSF using agro-industrial residues is currently used in a range of applications including classical applications such as antibiotics production, enzymes, composting, biosurfactants and biofuel production. Microbial α-amylases have several applications in paper, food, pharmaceutical, detergent, and textile industries. The enzyme α-amylase is meritorious due to their properties such as thermostability, Ca2+ -independent pH stability and pH profile which play important role in the development of bioprocess of different products. This review is focused on physiochemical properties of the bacterial α-amylases fermentation, structural and functional aspects of agro industrial residues and by products for α-amylase production.
