Fig. 4

Neighbor-joining phylogenetic tree of 16S rDNA sequences from the 56 halophilic bacteria with high hydrolytic enzymes activity. Red circle designates isolates from site 1, orange triangle designates isolates from site 2, and green rectangle designates isolates from site 3. Violet down-pointing triangle designates type strains used for sequence alignment neighbors. The tree branch distances represent nucleotide substitution rate, and the scale bar represents the expected number of changes per homologous nucleotide position
