A process for treating an animal waste in a waste holding facility to reduce sulfides and enhance efficient degradation of large amounts of organic matter with reduced odor. The process includes a first inoculation with sulfide-utilizing bacteria and a second inoculation with organic digesting bacteria and lytic enzymes. The second organic digesting inoculation is performed at a time when the sulfidecontent of the animal waste in the facility is adequately reduced to support organic digesting bacterial growth and efficient degradation of organic matter.

Why it's free to use
- Filed August 4, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 4, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 4, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
