ABSTRACT:
A method of producing a matrix of micro-organisms for extracting and gaining uranium from sea water, according to which the matrix is made of micro-organisms occurring in nature that are exposed to x-ray irradiations. These predetermined micro-organisms accordingly form colonies or threads and are filtered easily and cultivated. These micro-organisms accordingly form colonies or threads and are filtered easily and cultivated. These micro-organisms have a ratio of surface to volume that is relatively high. Subsequently, the thus irradiated micro-organisms are placed on a nutrient medium rich in uranium and are left there until colonies are formed. Thereupon, the surviving colonies of mutants are inoculated in a nutrient solution, and are then cultivated to produce the matrix.
