“…An attempt to use carbohydrases to accelerate the processing time, and improve the fiber opening with the elimination of lime, has been explored (Durga et al 2016;Jayanthi et al 2019). A noticeable improvement in the environmental area was observed, with reductions up to 80% on the usual parameters: chemical oxygen demand (COD); biochemical oxygen demand (BOD); and total dissolved solids (Jayanthi et al 2019). In the case of Durga et al (2016), the COD reduction achieved 90%, while TDS only 60%.…”

“…33 Durga et al used galactosidases and carbohydrates from Aspergillus terreus to replace the conventional lime to achieve fiber opening and pre-tanning, respectively. [34][35][36] The leathers obtained through these methods exhibited comparable physical properties to conventionally produced leathers, with reduced pollution load of total organic carbon (TOC) and COD. Amylase was used to assist protease in unhairing, with the result that it could not completely replace protease.…”

“…Further, the hydration and swelling degree of the neutralized dermis increases, the collagen destruction degree caused by enzymes increases [13]. It is important to consider that an effective removal of unstructured derm components, in particular polysaccharides and proteoglycans, is observed at the rawhide alkaline treatment stage due to enzymatic rawhide rehydration when used of sodium sulphide and calcium hydroxide in existing technologies [14]. The study of the collagen structure at eight stages of fresh ovine skins processing into dry crust leather using small-angle X-ray scattering is devoted to paper [15].…”
