Description of key information

Invertebrates: Under the conditions of the test, Sedolisin, batch PPF38268 was found not to be toxic to Daphnia magna at a nominal concentration up to 119.2 mg enzyme concentrate dry matter/L (equivalent to 24.7 mg active enzyme protein/L) after 48h exposure. Thus, no 48h EC50 could be calculated and must be > 119.2 mg enzyme concentrate dry matter/L (> 24.7 mg active enzyme protein/L).


Subtilisin, batch PPA 4046 was used as a read-across and the 48-hour EC50 of the test substance for the immobilisation of Daphnia magna was nominal 60.4 mg enzyme concentrate dry matter/L corresponding to 12.4 mg active enzyme protein/L.


Algae: Under the conditions of the test, Sedolisin, batch PPF38268 was found not to be toxic to Daphnia magna at a nominal concentration up to 119.2 mg enzyme concentrate dry matter/L (24.7 mg aep/L) after 48h exposure. Thus, no 48h EC50 could be calculated and must be > 119.2 mg enzyme concentrate dry matter/L (equivalent to > 24.7 mg active enzyme protein/L).


Subtilisin was used as read-across: The EC50 was 9.8 mg enzyme concentrate dry matter/L (corresponding to 5.02 mg active enzyme protein/L). NOEC for the growth rate was 0.042 mg enzyme concentrate dry matter/L. 

Additional information

The Subtilisin EC50 will be used as worst-case scenario.
