Fig. 6From: Improving the production of AHL lactonase AiiO-AIO6 from Ochrobactrum sp. M231 in intracellular protease-deficient Bacillus subtilisPhylogenetic tree of AiiO-AIO6 and the known lactonases. The phylogenetic analysis was constructed by the neighbor-joining method with the ClustalW (MEGA7). Bootstrap values from 1000 replicates are given on the nodesBack to article page
