Inexpensive α-amylase production and application for fiber splitting in leather processing

Abstract

Recently, the production of superior quality enzymes using waste sources has promoted greater research interest due to their enhanced enzyme activity, selectivity and stability.

Optimization of a single-step enzymatic beamhouse: toward eco-friendly leather manufacturing

“…The conventional chemical agents used in beamhouse could destroy and dissolve the hair, which is rich in proteins such as keratin, resulting in complex and costly wastewater treatment challenges. 55,56 In contrast, a significant advantage of enzymatic unhairing is that the structure of the hair after unhairing remains intact, making it possible to be recycled and reused. This method presents a more sustainable alternative, as depicted in Fig.…”

Partial Characterization of Amylase Enzyme from Newly Isolated Bacterial Strain from Garden Soil

“…Due to the commercial application of amylase enzyme in paper industry, induction of sugar from production of sugar syrup, fabrics decision, liquefaction of starch, brewing industry, pharmaceuticals is essentially important for industrial purpose (Ito et al, 1998;Ammar et al, 2002;Xie et al, 2014). Application of α-amylase for fiber splitting in leather processing was reported by Pandi et al, (2016).…”

Solid-State Fermentation as a Novel Paradigm for Organic Waste Valorization: A Review

“…Correspondingly, amylase produced by Bacillus subtilis on wheat bran through SSF showed a good performance in the fiber opening process developed on goat skins in comparison to chemicals and commercial enzymes. Besides, the employment of crude amylase during the process showed a lower pollution load (COD, TS) [109].…”
