초록
Plant-derived oils, carvacrol and thymol, when added to human or animal waste reduce the production of gas and short-chain volatile fatty acids, and the viability of total anaerobic bacteria and fecal coliforms. In an embodiment, carvacrol or thymol are combined with eugenol.
대표청구항▼
1. A method for inhibiting fermentative production of gaseous emissions, production of short chain volatile fatty acids and the viability of total anaerobic bacteria and fecal coliforms, and for promoting lactic acid accumulation in waste selected from the group consisting of excreta, feedlot waste
1. A method for inhibiting fermentative production of gaseous emissions, production of short chain volatile fatty acids and the viability of total anaerobic bacteria and fecal coliforms, and for promoting lactic acid accumulation in waste selected from the group consisting of excreta, feedlot waste and mixtures thereof, comprising applying to said waste an agent comprising eugenol and a component selected from the group consisting of carvacrol, thymol, and a mixture thereof in an amount effective to provide said inhibiting of fermentative production of gaseous emissions, production of short chain volatile fatty acids and the viability of total anaerobic bacteria and fecal coliforms, and promoting of lactic acid accumulation.2. The method of claim 1, wherein said waste is excreta of an animal.3. The method of claim 1, wherein said excreta is urine or fecal material.4. The method of claim 1, wherein said waste is human excreta.5. The method of claim 2, wherein said animal is a herbivore.6. The method of claim 2, wherein said animal is selected from the group consisting of cattle, swine, sheep, bison, horses, poultry, and exotic animals.7. The method of claim 1, wherein said waste is accumulated waste present in a pit toilet, portable toilet, manure treatment lagoon, or in an animal confinement area.8. The method of claim 1, wherein said agent is comprised of less than 50% eugenol.9. The method of claim 1, wherein said agent is applied to said waste at a concentration of at least 10 mM.10. The method of claim 1, wherein said agent is applied to said waste at a concentration of at least 13 mM.11. The method of claim 1, wherein said agent is applied to said waste at a concentration of at least 16 mM.12. A composition comprising waste selected from the group consisting of excreta, feedlot waste, and mixtures thereof and an agent comprising eugenol and a component selected from the group consisting of carvacrol, thymol, and mixture thereof, said composition produced as a result of the method of claim 1.13. The composition of claim 12, wherein said waste is excreta of an animal.14. The composition of claim 12, wherein said excreta is urine or fecal material.15. The composition of claim 12, wherein said waste is human excreta.16. The composition of claim 13, wherein said animal is a herbivore.17. The composition of claim 13, wherein said animal is selected from the group consisting of cattle, swine, sheep, bison, horses, poultry, and exotic animals.18. The composition of claim 12, wherein said agent is applied to said waste at a concentration of at least 10 mM.19. The composition of claim 12, wherein said agent is applied to said waste at a concentration of at least 13 mM.20. The composition of claim 12, wherein said agent is applied to said waste at a concentration of at least 16 mM.
