Noun
decolorization (countable and uncountable, plural decolorizations)
the removal of color from something; bleaching
Gram-negative bacteria cannot retain the violet stain after the decolorization step; alcohol used in this stage degrades the outer membrane of gram-negative cells making the cell wall more porous and incapable of retaining the crystal violet stain. Source: Internet
The decolorization step is critical and must be timed correctly; the crystal violet stain is removed from both gram-positive and negative cells if the decolorizing agent is left on too long (a matter of seconds). Source: Internet
Payen invented a decolorimeter, which dealt with the analysis, decolorization, bleaching, and crystallization of sugar. Source: Internet
This is because the thick peptidoglycan layer in the bacterial cell wall retains the stain after it is washed away from the rest of the sample, in the decolorization stage of the test. Source: Internet
