The adaptation of fatty acid composition of Chromohalobacter israelensis, a euryhalophilic bacterium, grown at different salt concentrations was studied. C. israelensis tolerated NaCl up to concentrations of 20% (w/v) and showed optimal growth at 7% (w/v). Major fatty acids of this bacterium were palmitic acid (16:0), stearic acid (18:0), palmetoleic acid (16:1cisΔ9), and cis-vaccenic acid (18:1Δ11). The salt concentration strongly influenced the fatty acid composition. In the presence of sub-optimal salt concentrations, the degree of saturation decreased, suggesting the importance of salt in maintaining the osmotic balance of the cell with its environment.



We thank Dr. Marcell Nikolausz, UFZ for the identification of the bacterial strain and the German Academic Exchange Service (DAAD) for providing financial support to Mr. Mutnuri.
