A composition which has bactericidal or bacteriostatic properties comprises coal-derived fulvic acid or a salt or a derivative thereof as active ingredient in a suitable carrier. The carrier is preferably water. ____________________________________________________________________________ Bacteriostatic and bacteriocidal method using fulvic acid derivatives United States Patent 5,204,368 Invento...

Many studies tested different feed additives, among these additives, humic substances (HS) have been used in livestock and poultry diets. Humic substances commonly present in nature as they are created from the organic matter decomposition, and are normally found in the soil and natural water. Active components of HS consist of humic acid (HA), humus, ulmic acid, fulvic acid, humin and certain ...

The biodegradation of 14C-labeled phenanthrene in the presence of particles of montmorillonite and fulvic and humic acid–montmorillonite complexes was studied in a batch system. A mathematical model that takes into account the contribution to mineralization by the slowly desorbing compound was used to calculate the initial mineralization rates. Sorption of phenanthrene to the particles was dete...

The phosphodiesterase 5A, hydrolyzes cGMP, is expressed in the corpus cavernosum and main player behind erectile dysfunction. Inhibition of PDE5A is therefore a natural target in treatments of erectile dysfunction. Fulvic acid which is a principal constituent of shilajit (a natural substance used against erectile dysfunction) was found to be stably bound to Q pocket of catalytic site of PDE5A a...

The objective of the present work was to evaluate malodor-reducing effects spraying fulvic acid in swine barns and providing growing pigs drinking water. Fulvic acids for were prepared at 0.02%, compost 0.1%. Prepared 1 L sprayed test nursery pig twice a week but not control barn. 0.02% provided 4 weeks group. In experiment compost, 3 additives consisted 1) probiotics 0.08 L, 2) 0.04 + 3) teste...

Young children with their hand-to-mouth activity may be exposed to contaminated soils. However few studies assessing exposure of organic compounds sequestrated in soil were realized. The present study explores the impact of different organic matters on retention of NDL-PCBs during digestive processes using commercial humic substances in a close digestive model of children: the piglet. Six artif...

Shilajit is a natural substance found mainly in the Himalayas, formed for centuries by the gradual decomposition of certain plants by the action of microorganisms. It is a potent and very safe dietary supplement, restoring the energetic balance and potentially able to prevent several diseases. Recent investigations point to an interesting medical application toward the control of cognitive diso...

The humic substances including humic acid (HA) and fulvic acids (FAs) extracted from a refuse compost were investigated the average conditional concentration quotients of the complexes formed by the reaction of heavy metals with the humic substances. The characteristics of these humic substances were previously investigated by a related study. The concentrations of the free ions of Pb, Cu, Cd, ...

The main objective of the study was to investigate the characteristics of dissolved organic matter (DOM) in leachate with different landfill ages through the chemical, spectroscopic, and elemental analysis. Humic acid (HA), fulvic acid (FA), and hydrophilic (HyI) fractions were isolated and purified by the XAD-8 resin combined with the cation exchange resin method. The analytical results of flu...
