Dependence of Marine Bdellovibrios on Potassium, Calcium, and Magnesium Ions

The Hebrew University-Hadassah Medical School, Department of Microbiological Chemistry, Jerusalem, Israel

ABSTRACT

Marine bdellovibrios show a specific requirement for K⁺, Ca²⁺, and Mg²⁺. Potassium is essential for high velocity and seems to be necessary for attachment of the free bdellovibrios. Calcium and magnesium are necessary for attachment and penetration. Magnesium also plays a role in maintaining the integrity of the bdelloplast. The adaptation of these bdellovibrios to the marine environment is manifested by their stringent cation requirements.
