From: Engineering of a genome-reduced strain Bacillus amyloliquefaciens for enhancing surfactin production
Surfactin production by GR167ID, GR167IDS and GR167IDT, and transcriptional levels of srfA operon in the strains. a Surfactin production; b specific productivity of surfactin (mg/g CDW, the ratio of surfactin production to cell dry weight); c transcriptional levels of srfA operon quantified via qPCR (the transcriptional level of srfA operon in GR167ID was set as 1). Values denote mean ± SD of triplicates (*P < 0.05, **P < 0.01)
