Biocidal actions

The action of certain chemicals that kill bacteria. Biocidal agents are used in turbine engine fuel to kill the bacteria and microbes living in water that condenses inside aircraft fuel tanks. If these microscopic organisms are not killed, they will multiply and form a scum that holds water against the aircraft skin and promotes corrosion. Biocidal additives are also put in aircraft dope used on cotton or linen fabric to kill bacteria that can destroy either of these organic fabrics.
