Abstract
A matrix of algae mutants and method of obtaining thereby uranium from sea water, according to which a matrix is prepared of uranium compatible algae mutants suitable for picking up uranium dissolved in sea water, which matrix is then placed in an area of the sea in which low and high tides pass streams of sea water through the above mentioned matrix.
Claims3
A method of preparing a matrix comprising in combination mutants for single cell green algae to be cultivated compatible with uranium and suitable for extracting uranium dissolved in sea water, which includes the steps of:
- introducing the algae into a sterilized nutrient solution adjusted to an acidity of ph 6, and formed of 3.8 grams sea salt, 0.03 grams of NH.sub.4 NO.sub.3 as well as 5ml earth extracts in 100 ml water, introducing in steps into the thus obtained solution uranium in the form of uranylnitrate until the quantity of uranium has been enriched to 250mg/l, subjecting the algae to X-ray radiation at a dose of approximately 50 kR, pouring the algae onto agar plates formed by employing a solution of 3.8 grams sea salt and 0.03 grams of NH.sub.4 NO.sub.3 and 5ml earth extracts in 100 ml water, inoculating the thus forming colonies individually and further cultivating the same in a nutrient solution formed by the solution of 3.8 grams sea salt and 0.03 grams NH.sub.4 NO.sub.3 and 5ml earth extracts in 100 ml water.
