Diffusion of Malachite Green in Polyacrylonitrile

Risk Assessment of Malachite Green in Food

Reduction of malachite green to leucomalachite green by intestinal bacteria.

Intestinal 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. The reduction of malachite green to the leuco derivative suggests that intestinal microflora could play an important role in the metabolic...

Determination of malachite green and leucomalachite green residues in rainbow trout in Sanandaj City

Background and Aim: Malachite green (MG) is an organic compound which his used as a dye in textile industry. This compound is applied incorrectly and illegally in aquiculture as an antimicrobial agent. This compound has mutagenic and carcinogenic effects. Materials and Methods: In this study we determined the concentrations of MG and leucomalachite green (LMG) in the muscle tissue of 90 rainbow...

An Isocratic Toxic Chemical-Free Mobile Phase HPLC-PDA Analysis of Malachite Green and Leuco-Malachite Green

This paper describes a reserved-phase high-performance liquid chromatographic (HPLC) method for detecting malachite green (MG) and leuco-malachite green (LMG) using an isocratic toxic organic solvent/reagent-free mobile phase. Chromatographic separations were performed an Inertsil WP300 C4 with 0.02 mol/L octane sulfonic acid–ethanol mobile phase and a photodiode-array detector. The total run t...

Use of malachite green for staining flagella in bacteria.

Preparations are prepared, using completely clean slides and aqueous suspensions of young bacterial agar cultures. A drop of the suspension is placed on one end of the slide; the slide is then tipped, making the suspension drain down to the opposite end (Society of American Bacteriologists, Manual of Microbiological Methods, McGraw-Hill Book Co., New York, 1957). Both the mordanting and the sta...
