Fulvic acids (FA) are a class of water-soluble compounds of humic matter, which is a
mixture of polyphenolic acids formed in nature as a result of chemical and biological
processes of decomposition of dead plants, animals and microorganisms. Recently, FAs
have been found to have antioxidant activity, nutraceutical properties, and physiological
effects on the human body: neuroprotective,
antimicrobial, anti-inflammatory [1], and
can also modulate the immune system and improve gastrointestinal function [2]. In this
regard, further study of the properties of peat originated FA is an important research
area for scientists from the Khanty-Mansiysk Autonomous Okrug - Yugra (KhMAO),
on the territory of which about 25% of Russian and 10% of the world's peat reserves are
concentrated.
In this work, we studied FA isolated from peat harvested on the territory of the
Tavolozhny tract (KhMAO). As a result of IR spectroscopy
of a freeze-dried sample,
there was obtained an IR spectrum containing a set of groups absorption bands
characteristic of fulvic acids: alcohol hydroxyls, aromatic and aliphatic carboxyls and
carbonyls, aliphatic C–H, and amides. Taking into account the absence of water in the
sample (less than 1%), a wide and intense absorption band with a maximum at 3407 cm
-

indicates the presence of strong hydrogen bonds between fulvic acid molecules, due to
which these humic substances form a spatial network in aqueous solutions. The results
of determining the atomic ratios in the sample also turned out to be characteristic of FC
and were: H/C=1.21; O/C=0.76; N/C=0.02. A microbiological
study of a sample of
fulvic acids showed that they do not support the growth and development of Bacillus
cereus (lat.), Gram-positive spore-forming soil bacteria.
