Acetato-N-2-(2-hydroxyethylamino)-ethyl-salicylideneimino(1-)copper and process for cultivation of cyanobacterium Spirulina platensis

摘要

The invention relates to a new coordinative compound from the class of salicylideneaminoalcoholates of transition metals and to a process for cultivation of cyanobacterium Spirulina platensis with its use as a compound increasing the copper content in the cyanobacterium biomass.It is claimed a coordinative compound acetato-N-[2-(2-hydroxyethylamino)-ethyl]-salicylideneimino(1-)copper of formula:It is also claimed a process for cultivation of cyanobacterium Spirulina platensis, including the cultivation of Spirulina in a nutrient medium containing, g/l: NaNO3 - 2.5; NaHCO3 - 16.8; NaCl - 1.0; K2SO4 - 1.0; K2HPO4 - 0.5; MgSO4·7H2O - 0.2; CaCl2 - 0.04; FeSO4·7H2O - 0.01; EDTA - 0.08; H3BO3 - 0.00286; MnCl2·4H2O - 0.00181; ZnSO4·7H2O - 0.00022; CuSO4·5H2O - 0.00008; MoO3 - 0.000015 and distilled water up to 1 L, at the temperature of 30...32°C, pH 9.5...10.0 and light of 2000...3000 lx. At the same time, on the 2nd day of cultivation into the nutrient medium is added acetato-N-[2-(2-hydroxyetthylamino)-ethyl]-salicylideneimino(1-)copper, in a concentration of 2...4 mg/L, in which the quantity of Cu2+ is 0.47...0.94 mg/L.
