Microalgal motility through day/night cycles
Newcastle University
Abstract
We have characterised the motility of the swimming microalga Chlamydomonas reinhardtii as a function of day/night cycles, to which the microalgal growth is entrained. Intriguingly, we find that the microalgae swim almost twice as fast during the night than during the day. I will connect this result with the bioenergetics of flagellar propulsion, discussing consequences for the distributions of cells in lab-based and environmental water columns.
