Detection of triphenylmethane dyes (TDs), especially the widely used malachite green (MG) and crystal violet (CV), plays an important role in safety control of aquatic products. There are two chromatic forms of TDs: oxidized or reduced. Usually, only one form can be detected by reported ELISA antibodies. In this article, molecular shape superimposing and quantum mechanics calculation were emplo...

An anaerobic sludge (AS), capable of decolorizing a variety of synthetic dyes, was acclimated and is reported here. The sludge presented a much better dye decolorizing ability than that of different individual strains. A broad spectrum of dyes could be decolorized by the sludge. Continuous decolorization tests showed that the sludge exhibited the ability to decolorize repeated additions of dye....

The characterization of a spore laccase from Bacillus vallismortis fmb-103, isolated from textile industry disposal sites, is described. The activity was 6.5 U/g of dry spore with ABTS as the substrate. The enzyme was quite stable at high temperature. It retained more than 90% of its initial activity after 10h at 70 °C. The enzyme demonstrated broad pH stability in both acidic and alkaline cond...

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...
