Since the publication of observations on the selective bactericidal action of gentian violet, 1 studies have been carried on in this laboratory with a large number of other dyes. The technique of divided plates, previously described, has been employed. The results with dyes similar in chemical structure to gentian violet have already been reported. 2 These dyes, like gentian violet, were found ...

The treatment of bleach effluent from pulp and paper Industry for COD, colour and AOX removal was investigated using Ultra violet/Hydrogen peroxide process photocatalysed by Titanium dioxide. The Ultra violet / Titanium dioxide process was able to remove 48% and 37% of COD and colour. The Ultra violet / Hydrogen peroxide process was able to remove 52% and 59% of COD and colour. The combined pro...

We report the first efficient trapping of rare-earth Yb atoms with a high-power violet laser diode (LD). An injection-locked violet LD with a 25 mW frequency-stabilized output was used for the magneto-optical trapping (MOT) of fermionic as well as bosonic Yb isotopes. A typical number of 4 × 10 atoms for Yb with a trap density of ∼ 1 × 10/cm was obtained. A 10 mW violet external-cavity LD (ECLD...

Borzani and Vairo (1959) reported that grampositive and gram-negative microorganisms are fundamentally different with respect to crystal violet adsorption. They claimed that the binding of crystal violet by gram-positive cells followed the Freundlich and the Langmuir adsorption laws; whereas the binding of crystal violet by gram-negative cells did not follow any known adsorption law. The presen...

Crystal violet exhibited characteristics of an uncoupler of oxidative phosphorylation, i.e. it released respiratory control, hindered ATP synthesis, enhanced ATPase activity, and produced swelling of isolated rat liver mitochondria. Maximal stimulation of respiration, ATPase activity, and swelling was observed at a concentration of 40 microM. The inhibition of State 3 respiration by oligomycin ...

New Guinea Impatiens (Impatiens hawkeri W. Bull) is an eye-popping landscaping plant of bright and colorful blooms. A highly efficient in vitro regeneration system via direct shoot organogenesis was established for the first time from hypocotyl with partial cotyledons Impatiens. Our results showed that explant sterilization method, basic medium type, AgNO3, sucrose growth regulators have signif...

In a previous communication 1 a selective bactericidal p roper ty possessed by gentian violet was described, and observations were reported to indicate the nature of this chemical affinity as exhibited in a study of a large number of representative bacteria. It was shown that bacteria could be sharply divided into two groups by their behavior toward gentian violet, either by staining the organi...

Dyes are the most abundant hazardous components existing in the environment because of their extensive use in industries. So, in the present study, two isoreticular Zn(II)-MOFs, TMU-16 and TMU-16-NH2, were used for the adsorptive removal of harmful cationic dyes from aquatic medium. In order ...

Acrylonitrile-Styrene co-polymer was prepared by solution polymerization and fabricated into nanofibers using the electrospinning technique. The nanofiber polarization was enhanced through its surface functionalization with carboxylic acid groups by simple chemical modification. The carboxylic groups’ presence was dedicated using the FT-IR technique. SEM showed that the nanofiber attains a unif...
