The Role of Microorganisms in Marine Corrosion
Abstract
A miniature Devanathan cell probe was modified to grow biofilms of anaerobic bacteria on palladium surfaces. Hydrogen permeation into the palladium was detected by measurement of the current passing through the cell. Permeation of the gas paralleled the growth curve of the bacteria adhering to the palladium surface. Bacteria in the liquid medium contribute minimally to hydrogen permeation. Very small populations of anaerobic bacteria growing on the palladium surface are capable of contributing significant quantities of hydrogen gas to the metal.
