Isolation, characterization and comparison of bacteria from swine faeces and manure storage pits.
Storage of swine manure is associated with the microbiological production of a variety of odorous chemicals including ammonia, organic acids and alcohols, and sulphides. Although largely the product of microbiological activity, little is known about the microorganisms present in swine manure. In order to gain a better understanding of the types and activities of the microorganisms present, repr...
متن کاملMedium for the enumeration and isolation of bacteria from a Swine waste digester.
A habitat-simulating medium was developed for the enumeration and isolation of bacteria from a swine waste digester. A roll tube medium with growth factors for strict anaerobes from previously studied anaerobic ecosystems was used to evaluate the effects of deletion, addition, or level of digester fluid, digester fluid treated with acid or base, rumen fluid, fecal extract, anaerobic pit extract...

متن کاملMethane Production from a Pilot-Scale Fixed-Film Anaerobic Digester and Plug-Flow Digester Loaded with High-Solids Dairy Manure
Three pilot-scale anaerobic digesters (two of a unique fixed-film design, of which one was fed micronutrients, one not, and an identically sized plug-flow digester, which served as the control) were monitored for methane production as a comparative indication of performance. All of these pilot-scale digesters were loaded daily with high-solids dairy manure, passed through a 1.5" x 3" mesh scree...
متن کاملSwine Manure Management
Production of pork is a major agricultural enterprise in the United States, and a majority of the production occurs in the Midwest (Ohio to Nebraska and Minnesota to Missouri) and North Carolina. Seventy-nine percent of the hogs and pigs marketed in 1987 (96.6 million head) were produced in the north-central region of the United States (Bureau of the Census 1989). Iowa has ranked first in hog i...
