Bacterial filament length has a minor effect on aggregation efficiency. (A) Phase-contrast image of RP1137 before shearing (left) and the same population of cells after shearing (right). (B) Aggregation of Nannochloropsis with nonsheared cells and sheared cells showing a statistically significant (P = 2.71E−7) but minor effect due to filament length. Bars and error bars represent the means and standard errors, respectively, of 16 independent aggregation reactions. A value of 100% is aggregation of all algal cells.
