Analysis of Unique Motility of the Unicellular Green Alga at Low Temperatures down to -8 °C.

Previous studies of motility at low temperatures in have been conducted at temperatures of up to 15 °C. In this study, we report that exhibits unique motility at a lower temperature range (-8.7 to 1.

Spatial Distribution of Flagellated Microalgae in a Quasi-Two-Dimensional Space.

Although the phenomenon of collective order formation by cell-cell interactions in motile cells, microswimmers, has been a topic of interest, most studies have been conducted under conditions of high cell density, where the space occupancy of a cell population relative to the space size ϕ>0.1 (ϕ is the area fraction). We experimentally determined the spatial distribution (SD) of the flagellated unicellular green alga at a low cell density (ϕ≈0.
