Abstract
A method and apparatus for killing plant and animal bacteria and plant viroids by electrically generated silver ions. The silver ions serve as germicidal agents in infection control and are generated by very slow electrical anodic corrosion of a silver wire located closely adjacent the infection site. In particular, a silver anode and a cathode of non-corroding metal are located in an electrolytic nutrient medium with the silver anode being within five millimeters of the infection site, and a direct voltage is applied to the anode and cathode in a manner passing a positive current in the microampere range into the silver anode causing it to corrode slightly and give off silver ions which produce a germicidal environment about the infection site.
Claims6
A method of killing plant bacteria and plant viroids to control plant infection while growing plant cells comprising the steps of:
- (a) placing a quantity of host plant tissue in an electrolyte nutrient medium;
- and
- (b) treating said host plant tissue with anodically generated silver ions in said medium in an amount sufficient to kill plant bacteria and plant viroids without causing damage to said host plant tissue.
A method of killing animal bacteria to control infection while growing animal cells comprising the steps of:
- (a) placing a quantity of host animal tissue in an electrolytic nutrient medium;
- and
- (b) treating said host animal tissue with anodically generated silver ions in said medium in an amount sufficient to kill animal bacteria without causing damage to said host animal tissue, said silver ions being generated by passing a positive electrical current having a magnitude less than 400 nanoamperes through a silver anode.
