Thermophilic aerobic digestion process for producing animal nutrients and other digested products
Patent
·
OSTI ID:5060843
Waste materials are digested by thermophilic bacteria to produce single-cell protein and vitamin B12. The bacteria are contained in the waste and are not inoculated. Thus, a hog manure slurry containing 10% solids was stirred with aeration in an insulated reactor to allow the temperature to be maintained at greater than 55/sup 0/. The temperature was maintained at 55-65/sup 0/ and the dissolved O/sub 2/ concentration at 1.5-3 ppm for 6 days. After 10 days reaction, the product was fed to hogs as 10% of their nutrient supply with no apparent adverse effects.
