It is a rapid test of three hours that suggests the milk whether is all good or bad for us. The resazurin test gives the bluish characteristic color to the milk that is all based on the quality of the milk. The milk quality is considered by only noting the color change degree of the milk.The Resazurin test is designed for assessing the quality of raw bulked milk. This is essentually a rapid bacteria estimation and can be carried out either as a 10 minute pass or fail, a 3 hour triple reading test or as the standard and generally accepted 1 hour test.

Procedure:
  1. Milk the sample thoroughly by inverting from one to another container.
  2. Pour 10 ml. …
  3. Add quickly 1 ml. …
  4. Mix the milk and dye thoroughly by inverting 2-3 times.
  5. Place the tubes in the water bath at the temperature of 37.5 0 C only for two minutes.
  6. The tubes are then removed from the water bath.

What does it mean when Resazurin turns pink?

Upon reduction, resazurin changes colour from blue to pink to clear, as oxygen becomes limiting within the medium (12). The first stage of reduction is due to the loss of an oxygen atom loosely bound to the nitrogen of the phenoxazine nucleus.

What is Resazurin dye used for?

Resazurin (7-hydroxy-10-oxidophenoxazin-10-ium-3-one, sodium) is a blue fluorogenic dye used as a redox indicator in cell viability and proliferation assays for bacteria, yeast or mammalian cells.

What resazurin means?

Resazurin is reduced to resorufin by aerobic respiration of metabolically active cells, and it can be used as an indicator of cell viability. It was first used to quantify bacterial content in milk by Pesch and Simmert in 1929. It can be used to detect the presence of viable cells in mammalian cell cultures.

What is COB test in milk?

1. The C.O.B test is for acid milk that is too acid, pH <5.8 or abnormal milk, e.g. colostrum milk or mastitis-affected milk. If a milk sample fails in the test, it contains either many acid and rennet producing micro-organisms or the milk has an abnormally high percentage of proteins, as in colostrum milk.

Why is resazurin pink?

Resazurin is a commonly used redox dye as it is inexpensive, non-toxic, and already effective in low doses and short incubation times 12. When incorporated to media, the blue colored resazurin first undergoes an irreversible reduction step to resorufin, which is pink at neutral pH values.

What color is resazurin when it is oxidized?

Colorless indicates the media is anaerobic and pink indicates that is was oxidized, and the media is no longer anaerobic.

What color is resazurin when it is reduced?

Resazurin (blue) diffuses into cells where it is irreversibly reduced by diaphorase enzymes to a highly fluorescent (pink) compound, resorufin.
