Microbial Diversity and Novelty Along Salinity Gradients
Microbial diversity is determined by the genetic diversity of ribosomal genes 16S for bacteria and archaea and 18S for protists. Microbial novelty indicates the uniqueness of the identity level of a given sequence based on BLAST search comparison against the ribosomal gene sequences previously reported in GenBank (usually <97% identity). The gradient of saline concentrations explored here ranged c. 20 times from 20 up to 370 g/L, when NaCl precipitates.
