Lysis profiles generated by infecting five strains of cyanobacteria with φMHI42, as determined by measuring absorbance at 750 nm – <i>M. aeruginosa</i> BC84/1 (A), <i>M. aeruginosa</i> 1450/8 (B), <i>Planktothrix agardhii</i> 137 (C), <i>Planktothrix rubescens</i> 9316 (D).

<p>Profiles begin at point of infection and are plotted on a logarithmic scale. Dashed lines are infected culture series, error bars represent standard deviation over three replicate cultures. The solid line represents triplicate control cultures, which were inoculated with the host but not subsequently infected with phage.</p>
