Abstract

Aspergillus nidulans is a filamentous fungus that is a potential resource for industrial enzymes. It is a versatile fungal cell factory that can synthesize various industrial enzymes such as cellulases, β-glucosidases, hemicellulases, laccases, lipases, proteases, β-galactosidases, tannases, keratinase, cutinases, and aryl alcohol oxidase. A. nidulans has shown the potential to utilize low-cost substrates such as wheat bran, rice straw, sugarcane bagasse, rice bran, coir pith, black gram residue, and chicken feathers to produce enzymes cost-effectively. A. nidulans has also been known as a model organism for the production of heterologous enzymes. Several studies reported genetically engineered strains of A. nidulans for the production of different enzymes. Native as well as heterologous enzymes of A. nidulans have been employed for various industrial processes.

Highlights

Enzymes have various kinds of industrial applications including pulp and paper, laundry, food, animal feed, brewery and wine, textile, and bioenergy industry [1,2,3]
AKB-24, 50% wheat bran and 50% black gram residue were used as a substrate for cellulase and xylanase production under solid-state fermentation (SSF) conditions. 4.04, 203.70, 3.70, 35.28, and 3674.94 IU/gds of FPase, endoglucanase, exoglucanase, β-glucosidase, and xylanase, respectively, were produced by cocultivation of A. nidulans AKB-25 and Penicillium sp
Bagga and Sandhu [33] utilized different carbon sources for cellulase production by A. nidulans and observed that delignified bagasse, paddy straw, and wheat straw resulted in higher production of cellulase compared to carboxymethyl cellulose, xylan, pectin, lactose, and glycerol

Summary

Introduction

Enzymes have various kinds of industrial applications including pulp and paper, laundry, food, animal feed, brewery and wine, textile, and bioenergy industry [1,2,3]. E worldwide availability of wheat bran makes it a potential substrate for enzyme production. The properties and availability of wheat bran represent it as a potential substrate for enzyme production [43, 45]. Wheat bran was employed as a low-cost substrate by Emericella nidulans NK-62 for xylanase production. AKB-24, 50% wheat bran and 50% black gram residue were used as a substrate for cellulase and xylanase production under SSF conditions. Jabasingh and Nachiyar [35] utilized sodium hydroxide pretreated sugarcane bagasse for cellulase production by A. nidulans MTCC344 using response surface methodology under SSF conditions. Bagga and Sandhu [33] utilized different carbon sources for cellulase production by A. nidulans and observed that delignified bagasse, paddy straw, and wheat straw resulted in higher production of cellulase compared to carboxymethyl cellulose, xylan, pectin, lactose, and glycerol.
