Bioremoval of Cu²⁺ from CMP wastewater by a novel copper-resistant bacterium Cupriavidus gilardii CR3: characteristics and mechanisms

Abstract

Bacteria of the genus Cupriavidus are known for the ability of resistance to various heavy metals and metal-binding capability.

Responses to copper stress in the metal‐resistant bacterium Cupriavidus gilardii CR3: a whole‐transcriptome analysis

“…All clean reads were subjected to assembly using the Bowtie program. The reference genomic sequences of C. gilardii CR3 of our previous work was used in this study, which contains 4992 genes (GenBank accession number: CP010516–CP010517) . Among all samples, 99% of the total reads (except for sample, 0.5–1) were mapped to the genome of C. gilardii CR3 (Table ).…”

“…The bacterium Cupriavidus gilardii CR3 is multiple metal‐resistant and was isolated from a tar pit in our previous work . We found the strain CR3 possesses the good ability for the removal of copper from chemical mechanical polishing (CMP) wastewater . In 2015, we completed the full genome sequencing of C. gilardii CR3.…”

Adsorption of cadmium by live and dead biomass of plant growth-promoting rhizobacteria

“…SEM-EDX is a useful tool for visual conrmation of surface morphology changes of cells aer absorbing metal ions and it has been extensively applied in research. 24,41,42…”

Biosorption and bioaccumulation characteristics of cadmium by plant growth-promoting rhizobacteria

“…In the study, biomass dosage (1.0 g l À1 ) was measured by weighing the freezedried ne powder of biosorbent, which was time-consuming but more accurate than methods in some previous studies. [28][29][30] Meanwhile, the batch adsorption experiments were conducted using resting biomass rather than growing cells in medium. Considering the different growth rates of strains in medium, it is inappropriate to compare adsorption efficiency and capacity between strains.…”
