Which biochemical test is suitable to determine the necessity of sodium ion for bacterial grow?

01 August 2014 1 776 Report

Please let me know which biochemical test is suitable to determine necessity of sodium ion for bacterial grow (special for differentiation between Vibrio spp. and Aeromonas spp.). Also, which culture medium should be used in this case?

Rene Kaden

I would prepare liquid media (e.g. Alkaline Peptone Water) with different concentrations of sodium ions and determine the turbidity after a defined time interval.
