Heavy metal bioaccumulation and toxicity with special reference to microalgae (2008, background): “Various mechanisms such as production of heavy metal binding factors and proteins (metallothionein, GSH and phytochelatin conjugates), exclusion of toxic heavy metals from cells by ion-selective metal transporters and excretion or compartmentalization have been proposed for reducing heavy metal toxi”
The effect of gibberelilic acid (GA3) on growth, metal biosorption and metabolism of the green algae Chlorella vulgaris (chlorophyceae) beijerinck exposed to cadmium and lead stress (2011, background): “The danger of heavy metal pollution is due to its ability to circulate within aquatic and nearshore ecosystems for a prolonged length of time [12, 13].”
Microalgae - A promising tool for heavy metal remediation. (2015, background): “These include the production of HM binding factors and proteins (metallothionein, GSH, and phytochelatin conjugates), exclusion of toxic HMs from cells by ion-selective metal transporters and excretion or compartmentalization (Arunakumara and Xuecheng, 2008; Hu et al., 2001; Gharieb and Gadd, 2004).”
Making the life of heavy metal-stressed plants a little easier. (2005, background): “These complexes acquire acid-labile sulphur (S2−) at the tonoplast, and form a ‘high molecular weight’ complex (HMW) with a higher affinity for Cd ions (Hu et al. 2001).”
