This activation reached maximum activity after 72 h.
Furthermore, the analgesic activity of compounds 2a c, 2e, 2o and 2v revealed a maximum activity after 5 h of injection compared to aspirin and the LD50 of compounds 2e and 2v was determined.
Alternatively, 'Candidatus Competibacter phosphatis' cultivated under certain controlled operational conditions in laboratory reactors only reach through adaptation their typical maximum activity after a certain period of cultivation and are not directly competitive from the moment of inoculation.
Both lipases exhibited maximum activity at pH 8.5 and could keep more than 80±2% of the maximum activity after incubating at pH 7.0~9.0 for 24 h.
Our results showed that CK activity increased after acute exercise, with maximum activity after 1 h and remained elevated for at least 48 h.
r27AROL could keep 85±3% of the maximum activity after incubating for 1 h at 40°C, and r28ROL retained 70±2% residual activity at the same condition.
Recombinant CpI maintained activities of 40%and50%0% of the maximum activity after incubation at pHs 2 and 9, respectively, whereas recombinants OcpA and OcpB scarcely showed activity after incubation at such pHs.
This is in agreement with the kinetics of activation of the CYC6 promoter, measured with the luciferase reporter gene, which reaches maximum activity after two days of induction and then decreases at three days [ 14].
Its stability was thus lower than that of Nit-ANigWT, which still exhibited 59, 24 and 6% of the maximum activity after 1-h incubation at 45, 50 and 55°C, respectively.
However, nonenzymatic hydrolysis of the thioester bond in the PPT1 substrate substantially increased between pH 7 and 8. Therefore, the assay pH was adjusted to pH 7, which showed a maximum activity after a blank correction.
