Abstract

We developed microscale approaches to monitor various responses of microalgal cells to external stimuli including light and chemical stress. Using these approaches, we found that phototactic and chemotactic responses of microglae have strong correlations with their photosynthetic efficiency. This result supports that microalgae utilize tactic response to obtain optimum energy by changing their positions. Based on the observation, high-throughput screening strategy was developed as a shortcut to isolation of strains with improved photosynthetic efficiency. The top strain isolated using this strategy showed highly improved photosynthetic productivity and lipid productivity compared to wild type.
