Figure 1.

Maximum likelihood tree using the Tamura-Nei model [16,17] indicating the phylogenetic relationships inferred from partial 16S rRNA gene sequences of alterin-producing Pseudoalteromonas strains (in blue) within the Pseudoalteromonas genus. Bootstrap values (expressed as percentage of 1000 replications) >50% are shown at branching point. A group of four bacteria was used as outgroup and tree was constructed using MEGA X [18].
