Description of key information

Invertebrates: Exposure of Daphnia magna to beta-N-acetylhexosaminidase based on nominal concentrations gave EC50 value of greater than 260.7 mg enzyme concentrate dry matter/L (equivalent to 100 mg active enzyme protein/L). The No Observed Effect Concentration (NOEC) was the highest concentration tested, 260.7 mg enzyme concentrate dry matter/L (equivalent to 100 mg active enzyme protein/L).


Algae: Exposure of Raphidocelis subcapitata to beta-N-acetylhexosaminidase revealed an ErC50 > 260.7 mg enzyme concentrate dry matter/L (equivalent to 100 mg active enzyme protein/L). NOEC for both growth rate and yield was 65.2 mg enzyme concentrate dry matter/L and LOEC was 130.4 mg enzyme concentrate dry matter/L. Yield EbC50 was 101.7 mg enzyme concentrate dry matter/L.
