Electroantennogram and behavioral responses of Anastrepha suspensa (Diptera: Tephritidae) to putrescine
and ammonium bicarbonate lures.
The eight studied amines were putrescine
(PUT), cadaverine (CAD), histamine (HIM), tyramine (TYM), serotonin (SRT), agmatine (AGM), spermidine (SPD) and phenylethylamine (PEM).
Increased Uptake of Putrescine
in the Rhiozosphere Inhibits Competitive Root Colonization by Pseudomonas fluorescens Strain WCS365.
It is worthy of note that the expression of OAZ1, OAZ2, and OAZ3 genes, which encode major regulators of ornithine decarboxylation to putrescine
through inhibition of ODC catalytic activity, and the expression of AZIN1 gene, which is involved in inhibition of antizyme (OAZ) family, did not change in the majority of CRC samples compared with normal samples.
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
Such a molecule would be able to bind to compounds produced by rotting meat with such evocative names as cadaverine and putrescine
, and increase its electrical resistance as a result.
The final enzyme preparation showed a specific activity of 42 Umg-1 determined by the guaiacol spectrophotometric method with putrescine
as a substrate .
Polyamines like spermine, spermidine and putrescine
were detected in elevated concentrations in urine in cases of a rapid regeneration of cells of certain tissue.
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 same company also supplied five bioactive amine standards: putrescine
(PUT), spermidine (SPD), histamine (HIM), tyramine (TYM) and tryptamine (TRM).
The process of metabolism of putrescine
and spermidine was also examined in tomato using GC-MS [4-5].
Evidence for horizontal gene transfer as origin of putrescine
production in Oenococcus oeni RM83.
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.
