The sorption of nickel, cadmium, and copper by cultured biomass from a naturally occurring bloom of Microcystis aeruginosa was demonstrated in two systems: cells suspended in culture medium and cells immobilized in alginate. Incubation in the absence of light, in the presence of metabolic inhibitors, and at 4 degrees C did not substantially decrease the copper accumulation by cells in culture medium. Heat-killed, formaldehyde-treated, and air-dried biomass samples sorbed nearly as much (or in some cases slightly more) copper as did viable samples.
研究表明,在两种体系中,铜绿微囊藻自然生长形成的生物量都能够吸附镍、镉和铜:一种是悬浮于培养液中的细胞,另一种是固定在藻酸盐中的细胞。在无光照、有代谢抑制剂和在 4°C 条件下孵育,并不会显著降低悬浮培养液中细胞对铜的积累。热灭活、甲醛处理和风干的生物量样本吸附的铜量与活样本几乎相同(在某些情况下略高)。
