Description of key information
Additional information
No specific information exists on the abiotic degradation of lysozyme hydrochloride in the environment via hydrolysis or photolysis. However, considering that any enzymes generally have a great biodegradation potential, possible abiotic degradation mechanisms in the environmental is expected to be of lower significance compared to biodegradation process.
The same conclusion was reached about abiotic degradation of other enzymes as Amylase, Cellulase, Lipase and Subtilisins (Protease) reported in the HERA documents (HERA 2005; HERA 2007).
Physical parameters as heating, dilution, mixing of solutions with air, etc. can impact the enzymatic function by denaturation, i.e. loss of activity and changes of the three-dimensional structure, which facilitates this proteolytic degradation process.
