Definition

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.

Introduction

Coastal salterns and inland salt lakes are widely distributed ecosystems around the world. In the Mediterranean region, there has been a long tradition to use solar saltern systems for salt production in seawater evaporation ponds. Multipond solar salterns are semi-artificial coastal systems designed to harvest common salt (NaCl) from seawater. Sequential precipitation of CaCO 3 and CaSO 4occurs during the first stages of...
