The In Vitro Degradation of Peacock Feathers by Some Fungi/ Der in‐vitro‐Abbau von Pfauenfedern durch einige Pilze

Abstract

The breakdown of peacock feathers by 20 fungi is studied and characterized by the release of protein and keratinase activity. AU the fungi except Aspergillus quercinus and Chaetomium globosum released protein in the medium. Maximum keratinase activity is measured in Gliocladium roseum. The degradation of feathers and existence of extracellular keratinase in these fungi is presented here for the fmt time. Zusammenfassung: Untersuchung uber den Abbau von Pfauenfedern durch 20 verschiedene Pilze, wobei die keratinolytische Aktivitiit durch die Bestimmung freigesetzten Proteins und der Keratinaseaktivitiit charakterisiert wird. AUe W e auDer Aspergillus quercinus und Cbaetonium globosum setzen Protein in das Medium frei. Die hochste Keratinaseaktivitiit zeigte Gliocladium roseum. Der Abbau von Federn und die Bildung extrazelluljirer Keratinase wird fiir diese Wze zum erstenmal beschrieben.

Reactional Ultrasonic Systems And Microwave Irradiation For Pretreatment Of Agro-Industrial Waste To Increase Enzymatic Activity

“…They can be obtained commercially or from submerged fermentation (FS) or solid-state fermentation (FES) through microorganisms (Mazotto et al 2013) such as fungi (Kushwaha 1983;Santos et al 1996), that are considered good producers of keratinases; they can also be isolated from keratinous waste disposal sites (Kaul and Sumbali 1997;Riffel and Brandelli 2006). When obtained in this way, they are designated "homemade" and can be used in crude or concentrated form, a technique that combines the interaction of the enzyme with salts and solvents so as to separate out interferents (Preczeski et al 2018).…”
