International Journal of Systematic and Evolutionary Microbiology. 55:2515-2518. Interpretive Summary: Odor emanating from anaerobic lagoons and swine production facilities has increased the tension among rural neighbors and among urban and rural residents. Storage of swine manure is associated with the production of a variety of odorous compounds, including ammonia, volatile organic acids and alcohols, and sulfides. In order to reduce production of odorous compounds, the responsible bacteria present in the fecal matter and manure storage pits must first be identified. We now report on the identification and scientific naming of a new species of anaerobic bacteria. The new species is Bacteroides coprosuis. This information will be of use to other researchers and environmental agencies.
Technical Abstract: Two Gram-negative staining, anaerobic, non-spore-forming rod-shaped organisms were isolated from a swine manure storage pit. Based on morphological and biochemical criteria, the strains were tentatively identified as Bacteroides, but they did not appear to correspond to any recognized species of this genus. Comparative 16S rRNA gene sequencing studies showed the strains were highly related to each other and confirmed their placement in the genus Bacteroides, but sequence divergence values of >10% with reference Bacteroides species demonstrated the organisms from manure represent a novel species. Based on biochemical criteria and molecular genetic evidence, it is proposed that the unknown isolates from manure be assigned to a new species of the genus Bacteroides, as Bacteroides coprosuis sp. nov. The type strain of Bacteroides coprosuis is CCUG 50528T = NRRL B-41113T.
