Background & Aims of the Study: Malachite Green (MG) is the most commonly used substance for dying cotton, food & pharmacy industries, paper, leather and silk. On inhalation it can cause difficult breathing, while on the direct contact it may cause permanent injury of the eyes of human and animals, burning sensations, nausea, vomiting, profuse sweating, mental confusion and met...

We studied the activity of the fluorescently labeled membrane transporter MalGFK(2), which transports maltose at the expense of ATP hydrolysis. We used a commercially available malachite green assay (SensoLyte MG phosphate assay kit; Anaspec) to quantify the liberated phosphate upon ATP hydrolysis. However, strong variations in phosphate concentration were measured when using the supplier's han...

The transport kinetics of the positively charged triphenylmethane dye, malachite green (MG(+)), across liposome bilayers effects the transport of monovalent inorganic cations when ionophores are present in the membrane. Three different types of ionophores characterized by different transport mechanisms have been studied. The ionophores are gramicidin A (gA) (a channel former), valinomycin (VAL)...

Pollution of water resources by various pollutants is nowadays a global environmental issue. Among the different type of water pollutants, dye represents a major polluting group. In this study, Azolla filiculides roots have been used for adsorption of Malachite Green (MG), a cationic dyed from aqueous solution. In this study, effects of operating parameters such as initial concentration of dye ...

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...

This study involves the electro-oxidation of malachite green, a triphenyl methane dye, extensively used in industries and aquaculture, and later banned in most developed countries because of its potential carcinogenicity, mutagenicity and teratogenicity in mammals. The study is conducted in a batch electro-chemical reactor using the catalytic anode (made of noble oxide coated, RuOx-TiOx, titani...

This study was conducted  to evaluate the antifungal effects of garlic (Allium sativum) and wormwood (Artemisia sieberia) 80-85% purity ethanolic extracts on rainbow trout (Oncorhynchus mykiss) eggs incubation and larvae survival rate. The experimental group divided to three different doses of garlic (50,100,200 ppm), wormwood (25, 50, 100 ppm), green malachite (2 ppm) as positive control group...

Advanced industrialization has caused an increase in the continuous discharge of hazardous effluents environment. This study evaluated potential laccase synthesized by Bacillus sp. NU2 to degrade five synthetic dyes. Sawdust, wheat bran and peels banana tangerine were utilized as carbon sources for bacterial growth production. The produced crude enzyme was purified homogeneity determine its mol...
