Abstract Nutraceutical industrial fenugreek seed spent (NIFGS), a relatively low-cost material abundantly available with nearly negligible toxicity for the bioremediation of malachite green (MG) dye from aqueous media, is reported. Studies on various parameters affecting adsorption capacity NIFGS were carried out to evaluate kinetics and equilibrium thermodynamics. All experiments designed at a...

The objective of this study was to determine the effect of different concentrations of anolyte on saprolegniasis in comparison with green malachite in rainbow trout hatcheries, in the northern part of Iran, Tonekabon. Nearly 5000 green eggs of Oncorhynchus mykiss (equivalent to 300 g) were obtained from a private farm in the north of Iran. The study was designed in 5 treatments, 0.25, 0.5, 30 a...

Embryonic mesenchyme limb (LB) and midbrain (CNS) cells cultured at high density were exposed to different concentrations of the fungicide malachite green (MG) and its major metabolite leucomalachite green (LMG). The concentration response curves were analysed, and two endpoints were calculated: the concentrations (μg/mL) that produced 50% inhibition of viability/proliferation (IC50-P) and diff...

Femtosecond time-resolved infrared spectroscopy was employed to study intramolecular charge transfer in triphenylmethane dyes, including malachite green (MG), malachite green carbinol base (MGCB), and leucomalachite green (LMG). A local excited state (LE) and a twisted intramolecular charge-transfer (TICT) state have been observed directly in MG. Furthermore, solvent-controlled TICT measurement...

Malachite green (MG) is a fluorogenic dye that shows fluorescence enhancement upon binding to its engineered cognate protein, a fluorogen activating protein (FAP). Energy transfer donors such as cyanine and rhodamine dyes have been conjugated with MG to modify the spectral properties of the fluorescent complexes, where the donor dyes transfer energy through Förster resonance energy transfer to ...

The removal of Malachite Green (MG) by Cocoa (Theobroma cacao) Shell Activated Carbon (CSAC) was investigated in present study. Adsorption studies were performed by batch experiments as a function of process parameters such as initial pH, contact time, initial concentration and adsorbent dose. A comparison of kinetic models applied to the adsorption of MG on CSAC was evaluated for the pseudo-fi...

Chromophore-assisted laser inactivation of protein function has been achieved. After a protein binds a specific ligand or antibody conjugated with malachite green (C.I. 42,000), it is selectively inactivated by laser irradiation at a wavelength of light absorbed by the dye but not significantly absorbed by cellular components. Ligand-bound proteins in solution and on the surfaces of cells can b...

in this study, rainbow trout (oncorhynchus mykiss) eggs were treated with effective doses of  daenensis thyme, thymus daenensis (20, 10 and 5 mgl-1) and mentha, mentha longifolia (10, 5 and 2.5 mgl-1), during incubation period (20 days) until hatching for 30 minutes per every other day as constant flow bath treatment method. the mortality level in normal control (without any treatment) was sign...

Adsorption of metal ions and dyes from water by cashew nut testa tannin resin (CATAR) was studied the effects temperature, initial pH, concentration time were investigated. Scanning electron microscopy (SEM) infrared spectroscopy (FTIR) reveal effective adsorption processes. Kinetic studies show that CATAR is complex thermodynamic parameters calculated spontaneous endothermic pollutants onto CA...
