Biodegradation of wool waste and keratinase production in scale-up fermenter with different strategies by Stenotrophomonas maltophilia BBE11-1

•Wool medium was first optimized for keratinase production.•Cell growth rate did a major impact on keratinase production.•A new strategy of glucose fed-batch process was developed.•High production of keratinase with wool medium was achieved in 30-L fermenter.•Stenotrophomonas maltophilia showed grea...
