Bacterial species identified in the Atacama lagoons. (A) TEM micrograph showing the four distinct detected morphotypes, labeled as A, B, C and D. (B) TEM micrograph showing the characteristic single lateral flagella of Halomonas (darker cell at left) and single polar flagella of Marinimicrobium/Marinobacter species (lighter cell at right). (C) PHYLIP phylogenetic tree obtained from the aligned 16S rRNA gene of the cultured isolate using BOSQUE. The numbers on the nodes represent bootstrap values with 10000 replicates. Only values over 50% are shown.
