Cyanobacteria Spirulina platensis due to its high biosorption and bioaccumulation capacity toward metal ions can be considered as an excellent candidate for environmental bioremediation. The effect of Zn and in different combinations on the accumulation capacity of Spirulina platensis biomass and its biochemical composition was investigated. Four Zn-containing systems with a different combination of metal ions (Zn; Zn/Cu/Sr; Zn/Cu/Ni; Zn/Cu/Sr/Ba) and different metal concentrations were modeled. Studied systems were introduced in the cultivation medium on the fifth day of biomass grow and experiments were performed in three variants, which differed by metal ions concentrations. Metal uptake by biomass was traced using neutron activation analysis. Spirulina platensis showed a high accumulation capacity for all metal ions present in the analyzed system. Because the metals were added at the beginning of the stationary growth phase, the contact with the biomass was only 24 h, even at the highest metal concentration in the systems, the accumulation of Spirulina platensis biomass was reduced by no more than 11.2%. Spirulina platensis biomass grown in a mono-metallic system expressed two biochemical indicators of stress: decrease of phycobiliprotein content and increase of malondialdehyde content. In biomass grown in the presence of Zn-containing multi-metallic systems, three indicators of stress were expressed: decrease of protein content, reduction of phycobiliprotein content, and increase of malondialdehyde content. Spirulina platensis biomass can be considered as an effective accumulator for the treatment of zinc-containing industrial effluents.

蓝藻螺旋藻由于其对金属离子的高生物吸附和生物积累能力，可以被认为是环境生物修复的极好候选者。研究了锌和不同组合对钝顶螺旋藻生物量积累能力及其生化组成的影响。模拟了具有不同金属离子组合（Zn；Zn/Cu/Sr；Zn/Cu/Ni；Zn/Cu/Sr/Ba）和不同金属浓度的四种含锌系统。在生物质生长的第五天将研究的系统引入培养基中，并在三种变体中进行实验，这些变体因金属离子浓度而异。使用中子活化分析追踪生物质对金属的吸收。螺旋藻对分析系统中存在的所有金属离子显示出高积累能力。由于在稳定生长期开始添加金属，与生物质的接触时间仅为 24 h，即使在系统中金属浓度最高的情况下，钝顶螺旋藻生物质的积累减少不超过 11.2%。在单金属系统中生长的钝顶螺旋藻生物量表达了两种胁迫生化指标：藻胆蛋白含量降低和丙二醛含量增加。在含锌多金属系统存在下生长的生物质中，表达了三个胁迫指标：蛋白质含量降低、藻胆蛋白含量降低和丙二醛含量增加。螺旋藻 生物质可被视为处理含锌工业废水的有效蓄能器。
