Increased synthesis of MAAs by exposure to high intensity artificial visible light also occurs in the Antarctic diatom Thalassiosira weissflogii, the prasinophyte Pyramimonas parkae, and most markedly in the dinoflagellate Amphidinium carterae (six-fold increase over control).171 However, high visible light exposure does not affect the MAA content of two other unicellular algae, Dunaliella tertiolecta (Chlorophyta) and Isochrysis sp. (Haptophyta). Supplemental exposures with UVA and UVB in combination and alone result in a variety of species-specific responses.

For eukaryotic microorganisms, the involvement of PolyPs in biochemical regulation under stress has also been observed. For example, the involvement of vacuolar PolyP in survival under osmotic or alkaline stress has been shown in algae and fungi. In the alga Dunaliella salina, alkalinization of the cytoplasm results in a massive hydrolysis of PolyP, resulting in pH stat. Various authors have suggested that the hydrolysis of PolyP provides the pH-stat mechanism to counterbalance the alkaline stress (Bental et al, 1990 Pick et al, 1990 Pick and Weis, 1991). 

The ammonium-induced cytoplasmic alkalization in the unicellular algae Dunaliella salina resulted in degradation of long-chain PolyPs to PolyP3 (Pick etal, 1990 Bental etal, 1990 Pick and Wess, 1991). The hydrolysis was shown to correlate with the recovery of cytoplasmic pH and might provide the pH-stat mechanism to counterbalance the alkaline stress.
