16S rRNA gene-based identification of bacteria isolated from lagoons Morrope and Bayovar.
Fig 2.
Phylogenetic tree based on 16S rRNA gene sequences (1206–1500 bp positions in the final dataset) inferred using the neighbor-joining method in MEGA7, the evolutionary distances were computed using the Kimura 2-parameter method, showing the phylogenetic positions of different saline isolates and type strains within the Streptomyces and Pseudonocardia genera.
Numbers at branching points refer to percentages of bootstrap values from 1000 replicates. Bar, 0.02 substitutions per nucleotide position was used. Bacillus cereus ATCC 14579T (AE016877) was the outgroup.
