The invention relates to a new chemical compound as ferrum content regulator in the cultivation of Spirulina platensis biomass used in medicine and food industry. A chemical compound is claimed, namely heptaazotate of hexa û(MyûBetaûalanineû(O,O'))ûMy3ûoxoûtri(aqua)triferrum(III) 3,5-hydrate as ferrum content regulator in the cultivation of Spirulina platensis cyanobacterium biomass. A process for Spirulina platensis biomass obtaining is also claimed, including preparation of the nutrient medium containing, g/l:NaHCO3û 6,8; K2HPO4À3H2Oû1,0; NaNO3û2,5; NaClû1,0; K2SO4û1,0; CaCl2À6H2Oû0,04; MgSO4À7H2Oû0,20; H3BO3û0,00286; MnCl2À4H2Oû0,00181; ZnSO4À7H2Oû0,00022; CuSO4À5H2Oû0,00008; MoO3û0,000015 and water û the rest. For inoculation is used 0,4 g/l suspension of Spirulina platensis and it is cultivated during 6 days at the temperature of 30à35?C, with an illumination of 3000à4800 lx and medium pH 9,5à10,0. Into the nutrient medium there is additionally added heptaazotate of hexa- (MyûBetaûalanineû(O,O'))ûMy3ûoxoûtri(aqua)triferrum(III) 3,5ûhydrate 0,04à0,05 g/l, batchwisely, in the first four days of cultivation.
