Abstract：
:We investigated the precipitation of carbonates by Nesterenkonia halobia in a liquid medium at different concentrations of salts and incubation times. N. halobia only produced crystals at salt concentrations of 2.5%, 7.5% and 15%. At 20% salt concentration no crystal formation was observed. Calcite, aragonite and dolomite were precipitated in different quantities, depending on the salinity of the medium and incubation time. Scanning and transmission electron microscopy, microanalysis and electron diffraction were all used to study in detail the morphology, composition and internal structure of the bioliths. We propose a mechanism for biolith formation involving both biological and inorganic processes.
