Cadmium Removal by Two Strains of Desmodesmus pleiomorphus Cells
The capacity of microalgae to accumulate heavy metals has been widely investigated for its potential applications in wastewater (bio)treatment. In this study, the ability of Desmodesmus pleiomorphus (strain L), a wild strain isolated from a polluted environment, to remove Cd from aqueous solutions was studied, by exposing its biomass to several Cd concentrations. Removal from solution reached a...
متن کاملTransfer ribonucleic acid from Scenedesmus obliquus D3.
Scenedesmus obliquus is a green alga whose cells have a well-defined nucleus, and contain a chloroplast. Even when grown in the dark these cells retain their chloroplast. Because of the toughness of the cell wall, extraction of tRNA requires either vigorous homogenization of the cells before phenol extraction or prolonged phenol extraction at 60°C. Determination of the amount of tRNA and its pu...
متن کاملAccumulation of Cu by Microalgae Scenedesmus obliquus and Synechocystis sp. PCC 6803
This study focused on the use of microbial potential for metal ion removal. Scenedesmus obliquus and Synechocystis sp. PCC 6803 were compared for accumulation of Cu in batch mode. During time course accumulation, S. obliquus accumulated Cu up to 124 μg mg -1 dry wt after 1h of incubation, whereas for Synechocystis sp. PCC 6803 it reached up to 64.9 μg mg -1 dry wt after 2h. Low biomass concentr...
متن کاملEffect of Nano-Al2O3 on the Toxicity and Oxidative Stress of Copper towards Scenedesmus obliquus
Nano-Al₂O₃ has been widely used in various industries; unfortunately, it can be released into the aquatic environment. Although nano-Al₂O₃ is believed to be of low toxicity, it can interact with other pollutants in water, such as heavy metals. However, the interactions between nano-Al₂O₃ and heavy metals as well as the effect of nano-Al₂O₃ on the toxicity of the metals have been rarely investig...
