Biomass of Arthrospira platensis enriched with lithium by bioaccumulation and biosorption process

Abstract

The process of production of lithium-enriched Arthrospira platensis biomass in bioaccumulation and biosorption processes was studied. Lithium, Na and Mg content in biomass was determined using the Proton Induced Gamma Emission technique. The effect of lithium on biomass amount and its biochemical composition was studied. The amount of biomass and proteins was not influenced by lithium action, while the content of phycobiliproteins, carbohydrates, lipids, chlorophyll a, and β-carotene was affected by lithium concentration as well as the phase of its introduction in the cultivation medium.
