Abstract
A method for inhibiting the growth of microorganisms in an aqueous medium comprises contacting the aqueous medium with a permeable body comprising material which interacts with the microorganisms. Such interaction involves a change in the chemical structure of the material resulting from the action of one or more of the microorganisms. The permeable body may take the form of a permeable bag containing plant fibers and may be used for the treatment of photoprocessor wash waters.
