Composition changes of phototrophic microbial communities along the salinity gradient in the solar saltern evaporation ponds of Eilat, Israel

Popis výsledku v původním jazyce

The planktonic and benthic microbial communities in 8 hypersaline evaporation ponds of Eilat, Israel, salinity between 58 and 329 g l-1, were studied by microscopic methods. Marked shifts in the species composition of phototrophic microbial communities were found along the salinity gradient. Planktonic communities consisted mainly of cyanobacteria and diatoms, except for the pond with the highest salinity, were dominated green alga Dunaliella salina. Species composition of benthic communities was markedly different in each pond. At the lowest salinities, mats of oscillatoriacean cyanobacteria, accompanied with diatoms, covered the sediment. The cyanobacterium Halothece sp. dominated the ponds of intermediate salinity where gypsum precipitated. The pondwith the highest salinity was not colonized by phototrophs. Photosynthetically active oxygenic microorganisms were found to abound even in deep layers of sediments (up to 5 cm) where light and oxygen are supposedly unavailable.
