5. Conclusions
In this study, significant differences were found in the effects of Mt
and Pal on the morphology and physiology of C. reinhardtii .
Layered Mt attached to the cell surface and could provide positive
effects for algal growth. In contrast, fibrous Pal wrapped around the
cell surface and significantly inhibited the algal photosynthesis.
Moreover, some Pal could even inserted the cells, leading to damage of
cell membrane and eventually cell death. Further research is needed to
explore interactions between various microalgae and clay minerals and
their influences on the biogeochemical cycles of elements in aqueous
environments.
