The researchers noted that not all pigments from the plant species could be processed into colorants due to low tinctorial
strength, and fragility, among others.
(8) Chatterton proposed the setting up of a tinctorial
lab and school "where those engaged in the trade can obtain expert advice and instruction" specifically in new methods of synthetic colour application.
These techniques are based on the tinctorial
properties common in mycobacteria and microorganisms of the genus Nocardia, Rhodococcus and Corynebacterium, known as acid resistant bacilli.
The identified microorganisms were classified according to their morphological, tinctorial
and biochemical pattern in species belonging to the families Enterobacteriaceae, Enterococcaceae, Streptococcaceae, Moraxellaceae, Aerococcaceae, Aeromonadaceae, Micrococcaceae, Pasteurellaceae, Pseudomonadaceae, Sphingomonadaceae, Burkholderiaceae and Dermacoccaceae.
The studied parameters of the research are: morphological, cultural, physiological, biochemical, and tinctorial
properties: Gram staining; growth in milk at various temperatures; resistance to sodium chloride, methylene blue, phenol and bile; growth in meat-peptone broth; NH3 culture formation from arginine; thermal resistance; the rate of milk coagulation; limit of acid; ability to ferment carbohydrates and alcohols.
Thus, availability of fiber to tinctorial
solutions becomes simpler.
Eosinophils are characterised by presence of abundant cytoplasm with coarse reflective granules  and are distinguished by their tinctorial
properties showing bright red staining with acid aniline dyes .
In addition to the difference in tinctorial
property, the population of eosinophilic granulocytes was also significantly less than that of basophilic granulocytes (P < 0.05).
Because of very high tinctorial
values (<1 mg/L) discharge of very small quantity of dye in water impart intense color which inhibits penetration of sunlight.
*** Liquid based-sample is put in a preservative bottle and smears are stained with tinctorial
stains that stain cytoplasmic keratins.
Pure culture identified by genus (species) by morphological, tinctorial
, cultural and biochemical properties.
The herb is endowed with a colourant of superior tinctorial
strength in comparison to synthetic dye of similar shade e.g.
