(A) Growth, (B) Lysine Production, and (C) Chlorophyll a Content of ALM.319 and TK.032. The values represent the mean ± SD of biological triplicates. Experiments were performed with ALM.319 induced with 1 mM IPTG, and TK.032 induced with 10–1000 ng ml⁻¹ aTc and 1 mM IPTG under continuous illumination (200 μE m⁻² s⁻¹) with 1 % CO₂ at 37°C. Chlorophyll a was extracted 46 hrs post induction. Chl a levels in TK.032 with 10, 100, and 1000 ng ml⁻¹ aTc were greatly reduced relative to ALM.319 (** represent p-value<0.05).
