Such solar salt works have rightfully been considered as natural laboratories for microbiological and geochemical investigations (Schneider and Herrmann, 1979). 2. The Saltern Environment The first evaporation ponds of multi-pond salterns have salinities close to that of the seawater used as the raw material for the production of salt. These ponds are typically inhabited by macroalgae as well as by a varied community of photosynthetic microorganisms including benthic cyanobacteria and diatoms, as well as by different 44 AHARON OREN kinds of protozoa, types of marine bacteria, as well as some higher organisms: macroalgae, crustaceans, and some other higher animals (Javor, 1989).

Cells in panel A and B were concentrated by centrifugation, causing collapse of the gas vesicles. 2H2O) are visible especially in panel B (arrows). Panels C-H show single cells of square halophilic Archaea not subjected to centrifugation. Refractile gas vesicles are visible in panel C, F, and G. Panel E and H show dividing cells. Scale bar = 10 µm. The flat square Archaea were first described by Walsby (1980) from a brine pool in Sinai, Egypt. After their biological nature was recognized, it rapidly appeared that they are abundant in saltern crystallizer ponds worldwide.
