Putrefying bacteria

Putrefying bacteria is the term used to describe bacteria involved in putrefaction of living matter.Putrefying bacteria turn nitrogen proteins into ammonium compounds....
. Decomposition

Decomposition

Decomposition refers to the process by which tissues of dead organisms break down into simpler forms of matter. Such a breakdown of dead organisms is essential for new growth and development of living organisms because it recycles the finite chemical constituents and frees up the limited physical space in the biome....
is a more general process. Putrefaction usually results in amine

Amine

Amines are organic compounds and functional groups that contain a base nitrogen atom with a lone pair. Amines are derivative s of ammonia, wherein one or more hydrogen atoms are replaced by organic substituents such as alkyl and aryl groups....

Putrescine

Putrescine is an organic chemical compound NitrogenHydrogen24NH2 . It is related to cadaverine; both are produced by the breakdown of amino acids in living and dead organisms and both are toxic in large doses....

Cadaverine

Cadaverine is a foul-smelling molecule produced by protein hydrolysis during putrefaction of animal tissue. Cadaverine is a toxic diamine with the formula NH25NH2, which is similar to putrescine....

Brief description of putrefaction of a human body with respect to time of death

2-3 days: Staining begins on the abdomen. The body begins to swell owing to gas formation.
3-4 days: The staining spreads and veins become discoloured.
5-6 days: The abdomen swells with gas (produced by the bacteria to decompose the body), and the skin blisters.
2 weeks : The abdomen becomes very tight and swollen.
3 weeks : Tissues begin to soften. Organs and cavities are bursting. The nails fall off.
4 weeks : Soft tissues begin to liquefy, and the face becomes unrecognisable.

The exact rate of putrefaction is, of course, dependent upon many factors, such as weather, exposure, and location.
