Aptamers switch on fluorescence of triphenylmethane dyes.
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...
متن کاملRemoval of Triphenylmethane Dyes by Bacterial Consortium
A new consortium of four bacterial isolates (Agrobacterium radiobacter; Bacillus spp.; Sphingomonas paucimobilis, and Aeromonas hydrophila)-(CM-4) was used to degrade and to decolorize triphenylmethane dyes. All bacteria were isolated from activated sludge extracted from a wastewater treatment station of a dyeing industry plant. Individual bacterial isolates exhibited a remarkable color-removal...
متن کاملOn the Mechanism of Bacteriostasis with Triphenylmethane Dyes.
The selective bacteriostatic effect of triphenylmethane dyes has long been known. It has been found by several authors (Churchman, 1928, and others) that these dyes used in gram staining also inhibit the growth of the grampositive microorganisms. The relations between bacteriostatic power and chemical structure of these dyes were studied by Browning and Gilmour (1913), Kligler (1918), Fairbroth...
متن کاملResistance of Bacterial Spores to the Triphenylmethane Dyes
1. Bacterial spores are highly resistant to the bactericidal action of the triphenylmethane dyes. Many Bacillus anthracis and Bacillus subtilis spores resist a saturated aqueous solution of gentian violet for 24 hours at 37 degrees C. They also resist exposure to the same dye solution for 10 minutes at 80 degrees C. 2. The selective bactericidal action of these dyes applies only to the vegetati...
