Fulvic acid (FA) and humic acid (HA) make up an important part of soil organic matter (SOM), and their binding capacity affects the fate of metal ions and plays an important role in metal mobility (Stevenson 1994; Tipping 1998; Gondar et al.
A large proportion of Cu in soil solution was bound to dissolved organic matter (represented by fulvic acid in WHAM model).
Hence we tested four different HS preparations--two naturally occurring HA from the Altteich peatland in Germany, one fulvic acid (FA) preparation from a Finnish spruce forest and a synthetic HA-like polymer (caffeic acid oxidation product, KOP) for their influence on the lipopolysaccharide (LPS)-induced TNF-[alpha] release in human U937 cells.
The researchers determined the total phenolic content of the extracts using the Folin-Ciocalteu method: 24145 [+ or -] 1508 mg of fulvic acid per 100 g for the skins, and 425 [+ or -] 33 mg of fulvic acid per 100 g for the shells.
The new product, which is extract drink richly containing minerals, amino acids, humic acid and fulvic acid, helps detoxify the body and maintain health.
Organomineralization has also been used to denote early diagenetic precipitation triggered by residual organic compounds such as fulvic acids, an area not treated here.
