Industrial wastewater containing heavy metals is a major environmental problem that needs to be treated. This study reported the ability of two fresh water algae cyanobacteria (Nostoc muscorum and Anabaena variabilis) to remove lead from aqueous solutions of four different initial concentrations (0–50 mg/L⁻¹) for 21 days under controlled laboratory conditions. Results obtained in this study showed a maximum removal of Pb(II) (97.8%) by N. muscorum at 15 mg/L⁻¹ initial metal concentration however the maximum removal by A. variabilis at the same concentration was 71.4% after 16 day of incubation. These N. muscorum appeared to be more efficient than A. variabilis for removing Pb(II). Algal growth, pigments in the algae cells were measured during incubation period. Lower concentrations of lead increased biomass, OD, chlorophyll a and carotenoids in both algae. On the other hand, higher concentrations of lead were inhibitory for growth.

含有重金属的工业废水是需要解决的主要环境问题。这项研究报道了两种淡水藻类蓝细菌（Nostoc muscorum和Anabaena variabilis）能够在受控实验室条件下从四种不同初始浓度（0-50 mg / L ^-1）的水溶液中去除铅的能力，持续21天。在这项研究中获得的结果显示出最大去除铅（II）（97.8％）由N. muscorum以15mg / L ^-1初始金属浓度，但最高去除由A.变异后16天以相同的浓度为71.4％孵化。这些粘液猪笼草似乎比A. variabilis用于去除Pb（II）。在孵育期间测量藻类生长，藻类细胞中的色素。较低的铅浓度会增加两种藻类的生物量，OD，叶绿素a和类胡萝卜素。另一方面，较高浓度的铅抑制生长。
