Positive Pressure Effect on Manganese Binding by Bacteria in Deep-Sea Hydrothermal Plumes

ABSTRACT

A positive pressure effect (1.4 to 3.3x) on the binding of Mn2+ by a natural population of bacteria in a deep-sea hydrothermal plume was discovered over the intermediate pressure range of 1 to 200 atm (1 to 200 bars; ca. 1.01 x 102 to 2.03 x 104 kPa). The data suggest Mn2+ binding is functionally barophilic rather than simply barotolerant.
