WebGoldacre and Phillips (1949) investigated the solvolytic reaction of malachite green and the formation of the carbinol at various pH values. For 2.7 x 10-4 M solutions at 25°C they found the following degrees of ionization shown in figure 1. Figure 1: Solvolysis of malachite green as function of pH From these results a pK of 6.9 was calculated. WebThe primary stain, malachite green, is a relatively weakly binding stain that attaches to the cell wall of vegetative cells and the spore wall of endospores and mature spores. In fact, if washed well with water, the stain comes right out of the cell walls of vegetative cells. In contrast, malachite green will not wash from the spore wall.
