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...
The cation of methyl green carries two positive charges, that of malachite green only one; but the two dyes behave towards tissue-constituents in almost exactly the same way. These dyes are not specific for chromatin. They colour certain objects that are devoid of DNA, even when they are used in very dilute solution. The granules of cells called Kornchenzellen in the connective tissue of the co...
Residues from the use of malachite green, a compound illegally applied as veterinary drug in aquacultures intended for human consumption, are frequently reported to occur in fish and fish products. Legally, zero tolerance applies to all residues of malachite green including its main metabolite leucomalachite green which is the dominating residue in tissues of exposed fish. In the European Union...
in this research, the removal of malachite green dye from textile wastewaters using polyaniline coated onto sawdust (pani/sd) has been investigated. ammonium peroxodisulphate was used as chemical oxidant for polymerization of polyaniline directly on the surface of sawdust. the effects of some important parameters such as ph, initial concentration, sorbent dosage, exposure time and temperature o...
The malachite green microtube (MGMT) susceptibility assay was performed directly on sputum specimens (n = 80) and indirectly on Mycobacterium tuberculosis clinical isolates (n = 60). The technique is based on the malachite green dye, which changes color in response to M. tuberculosis growth. The MGMT assay is simple and rapid and does not require expensive instruments.
Malachite green has been used as an effective compound to control external fungal and protozoan infections of fish since 1933 but it has never been registered as a veterinary drug for use in food fish because of its potential carcinogenicity, mutagenicity and teratogenicity in mammals. The present paper reviews negative sideeffects of malachite green including its accumulation and persistence i...
fungous infection to saprolegnia is the most important difficulties at the egg of acipenser persicus which is controlled by malachite green as an effective structure . because of the effects and adverse imposition on human and various fish, its use has been avoided in most of the world more than two decades approximately. this study was aimed to compare the antifungal effect of zinc oxid nano p...
BACKGROUND The P27-P55 (lprG-Rv1410c) operon is crucial for the survival of Mycobacterium tuberculosis, the causative agent of human tuberculosis, during infection in mice. P55 encodes an efflux pump that has been shown to provide Mycobacterium smegmatis and Mycobacterium bovis BCG with resistance to several drugs, while P27 encodes a mannosylated glycoprotein previously described as an antigen...
Contaminated water is the primary source of any disease. Water may be contaminated by number of pollutants and dyes are one of them. Malachite green (MG) dye is widely used as biocide in the aquaculture industry to controls fungal attacks, protozoan infections and also used in food and textile industries for various purposes. Surface and ground water is contaminated with dyes due to discharge o...
MG and SRB aptamers, which are short RNA sequences originally selected only for binding to malachite green or sulforhodamine B, can greatly enhance the fluorescence of normally nonfluorescent triphenylmethane dyes. MG aptamer enhances the quantum yields of malachite green (MG) and a novel rigidized derivative, indolinyl malachite green (IMG) by >2000-fold. SRB aptamer brightens patent blue V an...
