Early in the development of microbiology, milk was used as a convenient, rich growth medium for propagating bacteria. The litmus in the medium acts as both a pH indicator and a redox (oxidation-reduction) indicator. The test itself tells whether the bacterium can ferment lactose, reduce litmus, form clots, form gas, or start peptonization. [2]
Litmus is a water-soluble mixture of different dyes extracted from lichens. It is often absorbed onto filter paper to produce one of the oldest forms of pH indicator, used to test materials for acidity. In an acidic medium, blue litmus paper turns red, while in a basic or alkaline medium, red litmus paper turns blue. In short, it is a dye and ...

[1] [2] Once stained as part of a sample, these organisms can resist the acid and/or ethanol-based decolorization procedures common in many staining protocols, hence the name acid-fast. [ 2 ] The mechanisms of acid-fastness vary by species although the most well-known example is in the genus Mycobacterium , which includes the species ...
Delvotest is a broad spectrum microbial inhibition test used in dairy for testing antibiotic residue in milk and milk products. [1] It is used to ensure milk safety and is produced by the global company DSM.
It tests positive for the oxidase test, and is also a nonsaccharolytic bacterial species. Heat-stable lipases and proteases are produced by P. fluorescens and other similar pseudomonads. [4] These enzymes cause milk to spoil, by causing bitterness, casein breakdown, and ropiness due to production of slime and coagulation of proteins. [5] [6]
