Rhenium is a scarce and highly important metal for industry and technology. In the present study, the cyanobacterium (Spirulina) was used to remove rhenium and related elements (Mo and Cu) from mono- and polymetallic synthetic effluents. Metal ions in different concentrations were added to the culture medium on the first, third, and fifth days of biomass growth, and their uptake by the biomass was traced using ICP-AES technique. The accumulation of rhenium in the biomass was dependent on the chemical composition of the effluents, and the highest uptake of 161 mg/kg was achieved in the Re-Cu system. The presence of rhenium, copper, and molybdenum affected the productivity of Spirulina biomass and its biochemical composition (proteins, carbohydrates, lipids, phycobiliproteins, the content of chlorophyll and -carotene). With the growth of biomass in the presence of rhenium or rhenium and molybdenum, a pronounced increase in productivity and protein content was observed. The presence of copper in systems has a negative effect on biomass productivity and biochemical composition. may be of interest as a bioremediator of rhenium-containing effluents of various chemical compositions.
铼是一种在工业和技术领域稀缺且极为重要的金属。在本研究中，蓝藻（螺旋藻）被用于从单金属和多金属合成废水中去除铼及相关元素（钼和铜）。在生物量生长的第一天、第三天和第五天，将不同浓度的金属离子添加到培养基中，并使用电感耦合等离子体发射光谱（ICP - AES）技术追踪生物量对它们的吸收情况。铼在生物量中的积累取决于废水的化学成分，在铼 - 铜体系中实现了最高吸收量161毫克/千克。铼、铜和钼的存在影响了螺旋藻生物量的生产力及其生化组成（蛋白质、碳水化合物、脂质、藻胆蛋白、叶绿素和β - 胡萝卜素的含量）。随着在铼或铼与钼存在下生物量的生长，观察到生产力和蛋白质含量显著增加。体系中铜的存在对生物量生产力和生化组成有负面影响。作为各种化学成分含铼废水的生物修复剂可能具有重要意义。
