Abstract:
The investigation of processes connected with iron accumulation in biomass of algae represents an interest as from theoretical point of view as well from practical. The study of some new Fe(III)coordinative compounds influence on iron accumulation in spirulina biomass have been carried out. The coordinative compounds have been administrated at the cultivation medium through 3 modalities: in the first or in the third day of cultivation and supplementation on rates (1/2 dose of compounds in the first day and the rest in the third day). In the result of our investigations have been established, that the quantity of iron determined in biomass increases proportionally with concentration increasing of the tested compounds. The maximal iron content in biomass has been accumulated at 50mg/l compounds concentration and is not depending of modality of supplementation. The highest content of iron has been determined in spirulina biomass in presence of all studied coordinalive compounds in case of supplementation on rates. The content of iron in biomass depends on the iron concentration in the respective compound as well as on the nature of the compound. Thus, the highest quantitative values of iron have been determinated in spirulina biomass in case of supplementation on rates at the maximal concentration of the coordinative compounds (50 mg/1) its content in spirulina biomass is: Fe3O-Gly -1.20% Fe3O-Ala - 1.01% Fe3O-Val -0.64%. In conclusion, the results of our investigations demonstrate that the all three coordinative compounds of Fe(III) may be used in nanobiotechnology of spirulina cultivation for obtaining some new antianemic products.
