Contract awarded for 3500 - biolure (trimethylamine, putrescine
ammonium acetate), for attraction of fruit flies in slow release membranes, conh term in the field between 90 and 120 days
1995), nitrogen degradability in the rumen of steers, particularly by the biogenic amine (BA) putrescine
(Dawson and Mayne, 1997), have negative effects on visceral organs and meat quality (Fusi et al.
The most common biogenic amines found in foods are histamine, tyramine, cadaverine, 2-phenylethylamine, spermine, sperm idi ne, putrescine
, tryptamine, and agmatine.
When bacteria feeds on protein-rich diseased gum tissue, this process produces chemicals cadaverine and putrescine
, which smell of rotten flesh.
The major polyamines are found in every plant cell such as; spermidine (Spd), spermine (Spm) and putrescine
The basic cadaverine and putrescine
, are aliphatic diamines and are causative of the odor of dead animals that originate from the amino acids, arginine and lysine by bacterial decarboxylation.

Anchovies are associated with scombroid-poisoning due to biogenic amine contents such as histamine, putrescine
Other examples of microbe-facilitated amino acid metabolism include the generation of [gamma]-amino butyric acid (GABA) from glutamate via glutamate decarboxylase (52) and the production of putrescine

Bienzyme biosensors for glucose, ethanol and putrescine
built on oxidase sweet potato peroxidase.
The major polyamines comprise putrescine
, spennidine and spennine, which either occurs naturally or as free bases or bound to phenolics or other low molecular weight compounds or macromolecules (Galston & Kaur-sawhney, 1990).
