Effects of single or multiple genetic perturbations on (2S)-naringenin production.
Control strains contained the (2S)-naringenin heterologous pathway without an RNA-guided dCas9:sgRNA system. The sgRNA-expressing plasmids repressing single or multiple genes were further transformed into the control strain to investigate the effects of these systems on (2S)-naringenin production. Final OD600 values, average specific growth rates and concentrations of p-coumaric acid and (2S)-naringenin were measured from production strains after a total fermentation time of 48 h.
