Mouse chitotriosidase cleaving chitin belongs to the family of mammalian chitinases, whose biological functions are poorly understood. Chitotriosidase activity in mouse serum was shown to be much higher than in humans. The following interstrain differences were revealed in mouse chitotriosidase

Chitin amendment is a promising soil management strategy that may enhance the suppressiveness of soil toward plant pathogens. However, we understand very little of the effects of added chitin, including the putative successions that take place in the degradative process.
