Global environmental regulations are changing the leather industry. Conventional unhairing contributes most of the pollution in the industry, such as hydrogen sulfide and lime. Ever-increasing attention to the environmental impact of the leather industry has necessitated the development of enzymatic unhairing as a potent alternative to polluting ch...
Bacillus Subtilis is a saprophytic bacteria which has a widespread distribution in nature and can be easily isolated from soil microbes. Bacillus Subtilis AS1.398 is a major strain of Bacillus Subtilis used extensively in light industry and the pharmaceutical industry and is commonly used in the leather industry in China for depilation and bating....

... A major part of hair-saving unhairing process investigations is devoted to enzymatic unhairing [4,5]. Despite the fact that the enzymatic process has a serious advantage from an environmental point of view, i.e. wastewaters after the process are free from sulphides and hair degradation products, pure enzymatic unhairing is not widely used in the industry. ...
... Later, it was found to be produced by the aerobic bacterium Achromobacter iophagus and other microorganisms including fungi (Godfrey, 1996). Different authors reported various strains among Bacillus and Aspergillus genera as collagenase-producing: B. subtilis (Okamoto, 2001;Tran and Nagano, 2002;Rui et al., 2009), B. licheniformis (Baehaki et al., 2012), A. fumigatus (Reichard et al., 1990). ...
