The dye malachite green (MG) is used worldwide as a fungicide in aquaculture. It is a toxic substance which in aqueous solutions is partly converted into its non-ionic colorless form (leucocarbinol). The equilibrium between these two forms is pH-dependent (pK=6.9).

Malachite green photosensitive plates
Applied Optics, 1989An experimental study of the behavior of malachite green sensitized plates was carried out. The transmittance variation of the irradiated plates was taken as a parameter. It has been observed that photoreduction in the malachite green plates is present only when ammonium dichromate is added to the plates.

Malachite Green: A Toxicological Review
Journal of the American College of Toxicology, 1996Malachite green, an N-methylated diaminotriphenylmethane dye, is used primarily as a therapeutic agent in aquaculture. In solution, the dye exists as a mixture of the cation (chromatic malachite green) and its carbinol base, with the ratio depending on the pH of the solution; the dye also can undergo chemical and metabolic reduction to a leuco ...

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).

Biotechnology and Bioengineering, 2006
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 Fish Diseases, 1985
Abstract. A detailed review of malachite green and its chemical and physical properties as they relate to fisheries interests. Many of the confusions and misconceptions about malachite green are discussed. Its mode of action, toxicity and fate are considered.

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 ...
