The Cr(VI) Bioremediation Potential of Chlamydomonas Debaryana

Chemical Engineering Transactions, 2019
Chromium (Cr) is an essential industrial component and has many applications in industrial manufacturing. Anthropogenic activities can lead to the release of hexavalent chromium [Cr(VI)] as well as trivalent chromium [Cr(III)]. Cr(VI) is 1,000 times more

Microbial Chromium (vi) Immobilization in Saturated Aquifer Columns Using Culture Inoculated Soil

Chemical Engineering Transactions, 2019
Chromium exists in two oxidation states in the environment namely; Cr(VI) which is highly toxic, carcinogenic and mutagenic in nature and Cr(III) which is less toxic, mobile and is required in trace elements with human diets.

Increased Mitochondrial Fragmentation Mediated by Dynamin-Related Protein 1 Contributes to Hexavalent Chromium-Induced Mitochondrial Respiratory Chain Complex I-Dependent Cytotoxicity

Toxics, 2020
Hexavalent chromium (Cr(VI)) pollution is a severe public health problem in the world. Although it is believed that mitochondrial fragmentation is a common phenomenon in apoptosis, whether excessive fission is crucial for apoptosis remains controversial.

Characterization of Product and Potential Mechanism of Cr(VI) Reduction by Anaerobic Activated Sludge in a Sequencing Batch Reactor

Scientific Reports, 2017
Bioremediation of Cr(VI) and nitrate is considered as a promising and cost-effective alternative to chemical and physical methods. However, organo-Cr(III) complexes in effluent generally causes environmental concerns due to second-pollution. Here, Cr(VI)

Remediation of Cr (VI) by inorganic-organic clay [PDF]

, 2017
Application of inorganic–organic clays (IOCs) for the remediation of hexavalent chromium (Cr (VI)) and the effect of bisphenol-A (BPA) were investigated. IOCs were better adsorbents for the removal of Cr (VI) than organoclay.
