Keratinases belong to a class of proteases that are able to degrade keratins into amino
acids. Microbial keratinases play important roles in turning keratin-containing wastes into …

The continuous growth of poultry industry results in an increased amount of waste provided
from both production facilities and processing plants. The processing of poultry meat results …

Massive production of keratinaceous byproducts in the form of agricultural and industrial
wastes throughout the world necessitates its justified utilization. Chemical treatment of …

Aqueous two-phase systems (ATPS) are considered efficient and sustainable downstream
processing techniques in extracting and separating enzymes. In this work, we evaluated the …

Immobilization of enzymes is an effective and potential technique for improving the enzyme
characteristics and plays an important role in reducing the final cost of enzymatic reactions …

Extractive fermentation is an efficient downstream process to segregate the desired product
in a fermentative process. Here, an integrated extractive fermentation process with an …

The growing demand for natural coagulants led to an increased necessity for rennet
substitutes, promoting a search for new sources of proteases with coagulant properties. The …

This study aimed to purify and partially characterize a keratinolytic protease produced by
Bacillus sp. P45 through bioconversion of feather meal. Crude protease extract was purified …

Technological processes mediated by microorganisms and enzymes are promising
alternatives for treatment of recalcitrant residues. Keratinases hydrolyze keratin, the primary …

Since the mechanism governing the partitioning behavior of biomolecules, such as proteins
and enzymes, in polyethylene glycol (PEG)–salt aqueous two-phase systems (ATPS) is …
