decolorization

"S. indologenes" are Gram negative, but they can resists Gram decolorization.

Payen invented a decolorimeter, which dealt with the analysis, decolorization, bleaching, and crystallization of sugar.

The next process of decolorization of greige material into a suitable material for next processing is called bleaching.

Acid-fastness is a physical property of certain bacteria (and, less commonly, protozoa), specifically their resistance to decolorization by acids during staining procedures.

Trolox equivalency is most often measured using the ABTS decolorization assay.

After decolorization, the Gram-positive cell remains purple and the Gram-negative cell loses its purple color.

It is chemically aggressive and destroys many organic compounds, resulting in rapid decolorization and deodorization in addition to disinfection.

Optical absorption spectra were taken after different time durations using an Ocean Optics spectrophotometer to monitor the rate of decolorization of the test contaminant.

The Kinyoun staining method uses carbolfuchsin as a primary stain, followed by decolorization with an acid-alcohol solution and methylene blue as a counterstain.

Molasses Number is a measure of the degree of decolorization of a standard molasses solution that has been diluted and standardized against standardized activated carbon.

A mixture of ultrafine powder CuO/Cu(OH)Cl has been shown to be good in photo-catalytic decolorization of dyes, such as amido black, and indigo carmine.

The decolorization step is critical and must be timed correctly; the crystal violet stain will be removed from both Gram-positive and negative cells if the decolorizing agent is left on too long (a matter of seconds).

In the past few years, there have been many studies in the decolorization of azo dyes by lactic acid bacteria such as L. casei TISTR 1500, L. paracasei, Oenococcus oeni.

(f) The process comprising all the following operations - Processing with concentrated sulphuric acid, oleum or sulphuric anhydride - Neutralization with alkaline agents - Decolorization and purification with naturally active earth, activated earth, activated charcoal or bauxite.
