Hello everyone
I hope you are doing well.
I have a question about the algal reaction to external materials. I enriched algae by water-soluble vitamins, it shows an inverse result. on the other hand, the amount of the vitamin decreased in algae than control. How can I explain it? It's strange to me. I looking forward to your help. Thank you.
Dear Sirwe,
you posted an interesting question. In my opinion, the observed phenomenon could be a vitamin-induced negative feedback; since you provided such nutrient by introducing it in medium, algae could have down-regulated its synthesis.
Best,
Dave
Dear Davide
Thank you very much indeed. I agree with you, I am very eager to know how it's happened? Because I had the result for one species of algae, not another species. Do you have a reference for your answer? If you have it, please share it to me. I hope I can find an answer with researchers helping.
Best regards,
Sirwe
This is a good Question that asked by you Yas algae is effective for reaction on external material as per your questions i think you have to use some other solvents i think it will be works
Thanks
Nayan, thank you.
Do you mean that I can change the solvent for extraction of vitamin C? Am I right?
Best regards

- Algal studies remain necessary for risk assessment and their utility in ecotoxicology is the evaluation of lethal and sub-lethal toxic effects of potential toxicants on inhabitants of several ecosystems.
- Effects on algal photosynthetic apparatus caused by various chemical species have been extensively studied. The present chapter summarizes the published data concerning the toxicity of various organic and inorganic pollutants such as oils, pesticides, antifoulants and metals on photosynthesis of aquatic primary producers. Biochemical mode of action resulting in the disruption of photosynthesis depends on the chemical’s nature and the characteristics of the exposed microorganism.
- Observed differences in response and sensitivity by different species to the same toxicant were attributed to several algal characteristics including photosynthetic capacity, pigment type, cellular lipid and protein content, and cell size. Single species bioassays either for one chemical alone or in mixture have been well reported and tolerance of both marine and freshwater water-column phytoplanktonic species has been examined.
- Adequate published information on multispecies tests (communities) in laboratory and field studies exists. However, risk assessment on photosynthesis of microbenthic periphyton is inadequate, though it is essential especially for hydrophobic organic molecules.
- Further studies are required to evaluate the adverse effects of metabolites on aquatic microalgae.

Hi Joydeep
Thank you for your answer and suggestion.
