The interface between biological and geochemical components in the surface crust of a saline soil was investigated using X-ray diffraction, variable pressure scanning electron microscopy combination with energy dispersive spectrometry. Mineral compounds such as halite gypsum were identified crystallized around filaments cyanobacteria. A total 92 genera from bacterial community based on 16S gene pyrosequencing analysis. occurrence crystals, their shapes compartmentalization suggested that they separated NaCl immediate microenvironment cyanobacteria, some cyanobacteria communities sulfur bacteria may had physical control over distinctive structures produced. This suggests might directly or indirectly promote formation protective envelope made calcium sulfur-based compounds.
