AbstractSalinity is one of the important abiotic stress affecting microorganism growth and productivity. To survive these stresses most organisms have to stress-adaptation mechanisms. It's one of these things proline. We did not find any similar studies with P. aeruginosa and E. faecalis in our studies. The highest value for proline production at 30 ?C 100 rpm was in E. faecalis 11,074 U/ml and in E. coli 6,833 U/ml. The highest proline production in LB medium containing 37 ?C 100 rpm KCl was found to be in E. faecalis 14,604 U/ml and in E. coli 6,557 U/ml. However, there are studies with E. coli. This experiment revealed that the extracellular proline concentration is proportionally linked to the KCl stress. We should first mention that studies similar to those we were less common in the literature. We did not find any similar studies with P. aeruginosa and E. faecalis in our studies.
