Biofert Plusz proved to be of low toxicity to Desmodesmus subspicatus in a study conducted according to OECD Guideline 201 (72 h ErC50: 148 mg/L based on geometric mean measured concentrations).
The toxicity of Biofert Plusz towards the unicellular green alga
Desmodesmus subspicatus was investigated in a study conducted according
to OECD Guideline 201 (Alga, Growth Inhibition Test). Cultures of
Desmodesmus subspicatus were exposed to 5 Biofert Plusz concentrations
ranging from 339 to 3559 mg/L test material (nominal) corresponding to
geometric mean measured concentrations ranging from 126 to 1579 mg/L
test material. The concentration of the main component of Biofert Plusz
L-Threonine was determined by HPLC/UV. Based on geometric mean measured
concentrations the 72 h ErC50 and 72 h EyC50 were determined to be 528
and 254 mg/L, respectively, corresponding to 148 (ErC50)
and 71.4 mg dry matter/L (EyC50).
