Figure 2.

Maximum likelihood phylogenetic tree based on 16S rRNA sequences of M. adhaerens type strain (HP15) plus all type strains of the genus Marinobacter and the type species of the neighbor order Pseudomonadales. Sequence selection and alignment improvements were carried out using the Living Tree Project database [22] and the ARB software package [23]. The tree was inferred from 1,531 alignment positions using RAxML [24] with GTRGAMMA model. Support values from 1,000 bootstrap replicates are displayed above branches if larger than 50%. The scale bar indicates substitutions per site.
