Technical Abstract: Intensive modern livestock farming practices has resulted in the concentration of generated waste products into increasingly smaller locations. Lagoon treatment or deep pit storage are among the more favored methods used to handle liquid swine manure. The storage of swine manure is associated with the production of a variety of odorous chemicals, much of which is due to the incomplete digestion process associated with anaerobic systems. In addition, production of odorous compounds within confined facilities as used with swine can pose potential health problems to both the animals and human workers. Although production of these chemicals is the result of microbiological activity, little is known about the types of microorganisms responsible for their production. During the course of an ongoing study into the microbial diversity present within manure storage pits (Whitehead & Cotta, 2000), we characterized four strictly anaerobic, Gram-positive, asporogenous, rod-shaped organisms of uncertain taxonomic position. Based on the results of a polyphasic taxonomic study, it is proposed that the isolates be assigned to a new genus Hespellia, as Hespellia stercorisuis sp. nov. and Hespellia porcinus sp. nov.
