Fig. 2From: CRISPR interference (CRISPRi) for gene regulation and succinate production in cyanobacterium S. elongatus PCC 7942Effect of CRISPRi on PCC 7942 growth and persistent transgene repression. a Mean fluorescence intensity (FI) profiles. b Growth curves. The recombinant cells were cultured in 40 ml BG-11 medium containing Km/Cm. Wild-type (WT) cells were cultured in 40 ml BG-11 without antibiotics. The cells were cultured for 21 days, during which cells were sampled for OD730 or flow cytometry analysisBack to article page
