Fig. 1From: Improving the production of AHL lactonase AiiO-AIO6 from Ochrobactrum sp. M231 in intracellular protease-deficient Bacillus subtilisConfirmation of the disruptions of yrrN, ywpE, ymfH and tepA. PCR products were amplified from the genomes of wild‐type (lane WT) and mutant (lane MT) strains using verification primer pairs as described in “Materials and methods” section.
