Nutrient solution for culturing photosynthesizing microorganisms, process of its preparation and use
Abstract
The present invention relates to a nutrient solution for culturing photosynthesizing microorganisms, especially alga or blue-green alga containing NaNOi3, Ca(NOi3)i2.6 Hi2O, Ki2HPOi4, MgSOi4.7Hi2O, Nai2COi3, and a stimulation agent. The invention is characterized in that said stimulation agent contains at least one element being selected from the group of noble earth elements comprising scandium, yttrium, lanthanum, cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium.
The invention also relates to a process for preparing a nutrient solution for culturing photosynthesizing microorganisms containing at least one element being selected from the group of noble earth elements and the use of at least one noble earth element or a mixture of noble earth elements as a stimulation agent into the nutrient solution for culturing photosynthesizing microorganisms.
