Cellulases production from Aspergillus niger-ITV-02 using corn lignocellulosic residues

نویسندگان

چکیده

Cellulases are enzymes used in the hydrolysis of lignocellulosic residues for second-generation (2G) bioethanol production, low availability market, and high-cost impacts 40% total cost 2G production. Therefore, it is necessary to look sustainable alternatives its mainly produced by Aspergillus niger, their activity can be affected nitrogen concentration, use surfactants, carbon source, among others. The objective this work was identify with CMCase β-glucosidase A. niger ITV-02 from low-cost such as corn cob stubble two culture media (M1 M2). results showed that using stover medium M2 increased volumetric 1.4 1.7 times, respectively compared M2. Likewise, cellulase were identified carboxymethyl cellulose (CMC) 4- methyl-lumberyl-β-D-glucopyranoside (MUG). MUG correspond a glucoamylase, β-glucosidases, an exo β-xylosidase. In CMC following identified: exo-β-1,3-glucanase, endo -β-1,4 xylanase arabinosidase, endoglucanase.

Bioethanol potentials of corn cob hydrolysed using cellulases of Aspergillus niger and Penicillium decumbens

Corn cob is a major component of agricultural and domestic waste in many parts of the world. It is composed mainly of cellulose which can be converted to energy in form of bioethanol as an efficient and effective means of waste management. Production of cellulolytic enzymes were induced in the fungi Aspergillus niger and Penicillium decumbens by growing them in mineral salt medium containing al...

Production of Xylanases and Cellulases by Aspergillus Fumigatus Ms16 Using Crude Lignocellulosic Substrates

Xylanolytic and cellulolytic potential of a soil isolate, Aspergillus fumigatus (MS16) was studied by growing it on a variety of lignocellulosics, purified cellulose and xylan supplemented media. It was noted that carboxymethyl cellulose, salicin and xylan induce the production of endoglucanase, β-glucosidase and xylanase, respectively. The study revealed that Aspergillus fumigatus (MS16) co-se...
