Subtilisin is the proteolytic enzyme derived from the common bacteria
"Bacillus subtilis". It has been used in many enzyme-based detergents in
Australia for a number of years. Advantages- attack protein-based
such as food & blood; disadvantages - will be destroyed by very hot
* Correst me if I am wrong, you have to inactivate subtilisin somehow in a
house hold washing machine, changing temperature is probably the
easiest way. Anyway, very interesting topic, would love to hear more
discussion in industrial microbiology.
