Results and discussion
Applicant's summary and conclusion
- Conclusions:
- Pyrophosphoric acid achieves a growth rate on chlorella pyrenoidosa chick slightly higher than phosphoric acid at a concentration of 3E-4.
TPA may bring an accelerating action compared to phosphoric acid.
No difference on O2 emission were observed for algae exposed to pyrophosphoric or phosphoric acid.
Algae exposed to ATP show a photosynthetic activity sliightly higher than algae exposed to phosphoric acid.
Regarding CO2 absorption, stimulating action is higher for phosphoric acid than for pyrophosphoric acid or ATP.
