Sorption of malachite green on chitosan bead
Journal of Hazardous Materials, 2008Chitosan bead was synthesized for the removal of a cationic dye malachite green (MG) from aqueous solution. The effects of temperature (303, 313 and 323 K), pH of the solution (2-11) on MG removal was investigated. Preliminary kinetic experiment was carried out up to 480 min. The sorption equilibrium was reached within 5 h (300 min).

AbstractWe have developed a novel mobile bioprobe using a conjugate of a kinesin‐driven microtubule (MT) and malachite green (MG) as a platform for capturing MG RNA aptamers. The fluorescence of MG increases when it is bound to an MG aptamer, allowing MT–MG conjugates to work as sensors of RNA transcripts containing the MG aptamer sequence.

Journal of Hazardous Materials
Multi-target detection combined with in-situ removal of contaminants is a challenging issue difficult to overcome. Herein, a dual-emissive Eu3+-metal organic framework (Eu3+-MOF) was constructed by pre-functionalization with a blue-emissive ligand and post-functionalization with red-emissive Eu3+ ions using a UiO-66 precursor.

Reduction of malachite green to leucomalachite green by intestinal bacteria
Applied and Environmental Microbiology, 1997Intestinal microfloras from human, rat, mouse, and monkey fecal samples and 14 pure cultures of anaerobic bacteria representative of those found in the human gastrointestinal tract metabolized the triphenylmethane dye malachite green to leucomalachite green.

Critical Reviews in Analytical Chemistry, 2018
Malachite green (MG) has been widely used in the aquaculture industry as a fungicide and parasiticide because of its high efficiency and low cost, and it is commonly found in aquatic products and environmental water. However, MG and its primary metabolite, leuco-malachite green (LMG), are also toxic inorganic contaminants that are hazardous to the ...

Malachite Green - reducing Enzyme in Mycobacteria
Nature, 1959IN experiments with the lipids of different Mycobacteria we found that the acetone solution of lipids becomes green in colour as a result of certain oxidizing agents. A more precise examination revealed that such a change in colour occurred in the lipid solutions of only those bacteria which were grown in media containing malachite green.

Mutagenicity of malachite green and leucomalachite green inin vitro tests
Journal of Applied Toxicology, 1999The genotoxic potential of the fungicide malachite green (MG) and its reduced derivative leucomalachite green (LMG) was assessed in bacteria and mammalian cells using the standard Salmonella typhimurium/Ames and CHO/HGPRT tests. In vitro potential DNA damaging effects of MG and LMG were tested using the single-cell gel electrophoresis (Comet) assay on ...

Quirks of dye nomenclature. 6. Malachite green
Biotechnic & Histochemistry, 2016Malachite green was discovered independently by two researchers in Germany in the 19(th) century and found immediate employment as a dye and a pigment. Subsequently, other uses, such as staining biological specimens, emerged. A much later application was the control of fungal and protozoan infections in fish, for which the dye remains popular, although

Nonlinear studies of malachite green polymer
Optik - International Journal for Light and Electron Optics, 2013Abstract Solid-state dye-doped polymer is an attractive alternative to the conventional liquid dye solution. In this paper the spectral characteristics and the nonlinear optical properties of the dye malachite green in polymethylmethacrylate is studied.
