α, є-pentamethy lenediamine, NH 2(CH 2)5 NH2. A colorless liquid with a boiling point of 178°-179°C. Cadave-rine is readily soluble in water and alcohol and yields crystallizing salts. It is contained in the products of protein decay (putrefaction) and is formed from lysine during its fermentative decarboxylation. Previously, cadaverine was thought of as one of the ptomaines, but the toxicity of cadaverine is relatively low. Cadaverine is found in plants and can be obtained synthetically from trimethylenecyanide.

There are two possible mechanisms which may control the sequential appearance of lysine decarboxylase: (i) Repression of lysine decarboxylase requires a high concentration of an intracellular metabolite (cadaverine) and depression may set in immediately after the rapidly metabolizable carbon sources have been used up.
A lot of studies on biogenic amines such as histamine, tyramine, cadaverine, and putrescine as fish spoilage indicator have been recorded beforehand [22-26].
According to the effective concentration ranges, the studied amines formed two clearly distinguishable groups--primary amines (cadaverine, 1,7-diaminoheptane, histamine, and dopamine) and secondary plus tertiary amines (Table 1).
