dihydrochloride, cadaverine dihydrochloride (Sigma, St.
The second variable corresponds to HPLC quantification of biogenic amines (histamine, tyramine, putrescine
, cadaverine and phenylethylamine)
Antioxidant defense system in heat shocked wheat plants previously treated with arginine or putrescine
During PLBs induction, putrescine
exhibited higher levels as compared to spermidine and spermine (Figure 2).
Spermidine or putrescine
is the product of APAO, depending on the starting substrate, 3-acetoaminopropanal (3-AAP) or [H.sub.2][O.sub.2], respectively  (Figure 1).
Increased Uptake of Putrescine
in the Rhiozosphere Inhibits Competitive Root Colonization by Pseudomonas fluorescens Strain WCS365.
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.
Although their amounts in wine are quite low when compared with those in other fermented food products, the presence of other compounds in wine composition, such as ethanol, acetaldehyde and other biogenic amines (putrescine
and cadaverine, for instance) could enhance their side effects (ANCINAZPILICUETA et al., 2008; SOUFLEROS et al., 2007).
The major polyamines are found in every plant cell such as; spermidine (Spd), spermine (Spm) and putrescine
The process of metabolism of putrescine
and spermidine was also examined in tomato using GC-MS [4-5].
