Figure 2: Correlation between phototaxis and photosynthetic efficiency in diverse strains.

From: Microfluidic high-throughput selection of microalgal strains with superior photosynthetic productivity using competitive phototaxis

Figure 2

(a) Scatter plot showing the correlation between skewness of arrival time distribution and inverse average arrival time of 100 strains, including the wild-type strain (CC-125) and 99 randomly selected insertional mutants with wide range of PSII operating efficiency (Y(II)) (R2 = 0.84). (b) Scatter plot showing the correlation between Y(II) and inverse average arrival time of the 100 strains (R2 = 0.69). (c) Scatter plot showing correlation between Y(II) and skewness of arrival time distribution of the 100 strains (R2 = 0.72). Cells were grown photomixotrophically under continuous low light condition (50 μmol photons m-2s-1). Phototactic response was measured on 6,600 cells per analysis. The yellow diamond: the wild type (a–c). Data are the mean of three biological replicates.
