The effect of the endogenous promoter modification on the expression of TGase in S. lividans. a Partially deleting the 5′-end of the TGase promoter region. b Partially deleting the 3′-end of the TGase promoter region. The recombinant S. lividans TK24 were inoculated into 30 mL of medium (which contained 50 μg/mL apramycine) and cultured at 30 °C and 200 rpm for 48 h
