Abstract: Keratinolytic microorganisms have become the subject of scientific interest due to their ability to biosynthesize specific keratinases and their prospective application in keratinic waste management. Among several bacterial classes, actinobacteria remain one of the most important sources of keratin-degrading strains, however members of the Micrococcaceae family are rarely scrutinized in regard to their applicatory keratinolytic potential. The tested Micrococcus sp. B1pz isolate from poultry feather waste was i… Show more

“…Bacterial culture is capable of utilizing the chicken feathers as sole carbon and nitrogen source ( Jeong et al, 2010 ). Feather degradation started from its tiny entity, i.e., barbules and the barbs, fibers along with the shaft region also digested by bacteria ( Laba et al, 2015 ). Here, keratinase from Thermoactinomyces strain RM4 is thermostable and organic solvent tolerant, which has potential role in feather degradation and plant growth promotion.…”

“…Various bacteria, actinomycetes, and fungi are known to produce keratinases that degrade keratinous waste found in nature ( Brandelli et al, 2010 ). Keratinolytic microbes have become paramount important among the scientific interest owing to their capacity to produce specific keratinases and their subsequent significance in keratinic waste management ( Laba et al, 2015 ; Wang et al, 2015 ). In the present decade, keratinase research has gained momentum because of its additional industrial and biotechnological applications other than those in the conventional sectors of proteases ( Gupta and Ramnani, 2006 ; Tork et al, 2016 ).…”

“…This cleavage of the disulphide bond was carried out by sulfitolytic activities, which was determined by detecting free sulfhydryl groups in the culture media; these results were in agreement with the study of Onifade et al ( 1998 ). The sulfitolytic cleavage of cystine was carried out by means of excess sulfite released by the microbial cells and was previously studied in filamentous keratinolytic fungi and actinomycetes; however, this pathway was also detected in bacterial degradation (Laba et al 2015 ). Such disulphide bonds cleavage during microbial degradation was previously described in Streptomyces pactum (Böckle et al 1995 ).…”

“…Many reports about Nocardiopsis showed its ability to degrade feather (Saha et al, 2013;Suneetha, Kumar, & Nimesh, 2014). Many members of Micrococcus have been isolated from poultry feather waste, these organisms confirmed to produce proteases and showed its ability to degrade feather (Laba, Choinska, Rodziewicz, & Piegza, 2015).…”
