Embodiment 1

[0168] Example 1 - Screening of compounds with anti-urealytic properties

[0169] Example purpose

[0170] Seventy-one commercially available compounds were screened for their anti-urealytic effects on pure Klebsiella pneumoniae cultures and purified Canavalia urease (JBU).

[0171] Materials and methods

[0172] Medicines and equipment.

[0173] Phenylphosphodiamide (PPDA), 97% was purchased from Fisher Scientific (Roskilde, Denmark). N-(n-butyl)phosphorothioate triamide was purchased from Carboxens Limited (Compton, UK). Liuric acid was purchased from Alfa Aesar (Karlsruhe, Germany). Iron(III) dimethyldithiocarbamate and 2-hydroxy-1,2-bis(2-thienyl)ethan-1-one were purchased from TCIEEurope (Zwijndrecht, Belgium). All other chemicals were purchased from Sigma-Aldrich and used as received unless otherwise stated. All equipment was purchased sterile or autoclaved prior to use. All solutions were autoclaved or sterile filtered through sterile filters with a pore size...

Embodiment 2

[0188] Example 2—Validation of Synergistic Inhibition of Ammonia Production in Complex Samples and Pure Cultures

[0189] Example purpose

[0190] Some representative compounds assayed in Example 1 were combined in pairs to test potential synergistic inhibition of ammonia production in swine fecal slurries. After establishing that tannin and fluoride were responsible for the synergistic inhibition in swine fecal slurry, the mixture was tested in pure bacterial cultures to demonstrate that tannin (TA) and fluoride were observed in complex samples (swine fecal slurry) The synergistic inhibitory effect of compound (F) on ureolytic bacteria was not dependent on unknown components present in the fecal slurry, as it was shown in pure bacterial cultures grown in well-characterized minimal media.

[0191] Materials and methods

[0192] Kjeldahl method.

[0193] Tannic acid, sodium fluoride, NaOH, HCl and H 3 BO 3 Available from Sigma-Aldrich.

[0194] Total ammonia nitrogen ...

Embodiment 3

[0207] Example 3 - Tannic Acid and Fluoride - Reduced Ammonia Generation

[0208] Example purpose

[0209] demonstrated the synergistic inhibitory effect of a mixture of tannic acid and fluoride over a range of concentrations on urea breakdown in swine manure slurries (measured by the concentration of ammonia gas in solution) and showed that the reduction in ammonia gas production resulted in more than 12 days of swine manure Reduction of ammonia emissions in the slurry (reduced ammonia concentration in the headspace).

[0210] Materials and methods

[0211] Kjeldahl method.

[0212] Same procedure as described in Example 2.

[0213] Headspace measurements.

[0214]Ammonia emissions were measured at ambient temperature (22-24° C.) in headspace experiments. Pig urine (30 ml) and 10 g of frozen pig manure were thawed and added to nine 100 mL reactors, respectively, and mixed with different concentrations of tannic acid and sodium fluoride. Tannic acid and sodium fluori...

Abstract

The present invention relates to a composition comprising tannin, preferably tannic acid, and fluoride for reducing the production and emission of ammonia gas, methane and / or odor. The invention also relates to related uses of such compositions.

Description

technical field [0001] The present invention relates to compositions comprising tannins and fluorides which significantly reduce ammonia, methane and odor emissions. In particular, the invention relates to the reduction of ammonia from animal manure using a composition comprising tannic acid and sodium fluoride. Background technique [0002] Industrial agriculture produces large quantities of manure slurries (a mixture of livestock manure and urine) from intensive animal production. The manure slurry is typically used as a field fertilizer or for biogas production. The emission of biogas in fecal slurry raises many environmental and social concerns. For example, the emitted ammonia (NH 3 ) is an economic problem in crop cultivation, which leads to the loss of fertilizer nitrogen, and the discharged ammonia gas is deposited in the nearby environment, causing harm to the water ecosystem and vegetation, and the discharged ammonia gas forms a greenhouse through the process of...
