Microalgae are capable of using bicarbonate (HCO3-) directly as an inorganic carbon species. Despite the importance of HCO3- in aquatic photosynthesis, little is known about the chemotaxis of microalgae towards HCO3-. Here, we demonstrated the chemotaxis of a model alga, Chlamydomonas reinhardtii, to HCO3- using an agarose gel-based zero-flow microfluidic device for generating a stable concentration gradient. We found C. reinhardtii showed the strongest chemotaxis towards HCO3- at the concentration of 26mM in the microfluidic system. We also observed that the various physiological conditions, such as circadian rhythm, mutation, and treatment of inhibitor have influence on the chemotaxis.
