Description of key information

Biodegradability studies according to OECD 301 test guidelines have been performed with a wide variety of industrial enzymes. Regardless of the enzyme class industrial enzymes are found to be readily biodegradable.

The physico-chemical properties of enzymes including logPow are very similar. Further, they are proteins built up of amino acids and the type, order and number of the amino acids in the polymer differs between enzymes, determining the 3 -dimensional structure, the activity and specificity of the individual enzyme type. Because all enzymes are built up of the same amino acids the physical and chemical characteristics will be very similar for different enzymes, and hence read-across from other enzymes should be fully applicable for the present endpoint.

The overall conclusion is that xanthan lyase is readily biodegradable.
