The technology of indoor cultivation of Nostoc sphaeroids Kütz is relatively mature, but for industrial cultivation, indoor cultivation has the disadvantages of high energy consumption and high cost. In order to find the appropriate amount of calcium concentration required for outdoor cultivation, and to pave the way for mass production of Nostoc sphaeroids Kütz, in this study, the Nostoc sphaeroids Kütz wwas cultivated. The pH, chlorophyll content, polysaccharide content, protein content and phytolithoprotein content of Nostoc sphaeroids Kütz were measured in different concentrations of calcium nutrient solution. The result showed that, with the increase of calcium concentration in outdoor cultivation, the growth of Nostoc sphaeroids Kütz was firstly inhibited and then promoted.
