| description of methanobrevibacter gottschalkii sp. nov., methanobrevibacter thaueri sp. nov., methanobrevibacter woesei sp. nov. and methanobrevibacter wolinii sp. nov.. | formal nomenclature is proposed for five methanogens, isolated from horse, pig, cow, goose and sheep faeces, that represent four novel species of the genus methanobrevibacter. the four species, methanobrevibacter gottschalkii sp. nov., methanobrevibacter thaueri sp. nov., methanobrevibacter woesei sp. nov. and methanobrevibacter wolinii sp. nov., are distinguished from each other by a lack of genomic dna reassociation and from previously described members of the genus on the basis of differences ... | 2002 | 12054244 |
| identification and quantification of methanogenic archaea in adult chicken ceca. | by using molecular methods for the identification and quantification of methanogenic archaea in adult chicken ceca, 16s rrna genes of 11 different phylotypes, 10 of which were 99% similar to methanobrevibacter woesei, were found. methanogen populations, as assessed by cultivation, and the 16s rrna copy number were between 6.38 and 8.23 cells/g (wet weight) and 5.50 and 7.19 log(10)/g (wet weight), respectively. | 2007 | 17085694 |
| molecular profiling and identification of methanogenic archaeal species from rabbit caecum. | during a comparison of 16s rdna pcr-denaturant gradient gel electrophoresis (dgge) profiles of methanogenic archaea from rumen fluid, rabbit caecum and pig feces, a unique band common to all rabbit caecum samples was observed. dgge profiling also showed that the methanogen community from the new zealand white adult rabbits is different and less complex than the methanogen communities from the rumen and pig feces. small subunit ribosomal gene sequences of methanogenic archaea were subsequently re ... | 2010 | 20950344 |
| archaeal characterization of bioaerosols from cage-housed and floor-housed poultry operations. | although bioaerosols from both cage-housed (ch) and floor-housed (fh) poultry operations are highly concentrated, the concentrations of dust, endotoxin, and bacteria are significantly higher in fh bioaerosols. workers from ch operations have reported a greater prevalence of respiratory symptoms. to date, archaea have been examined in swine and dairy bioaerosols but not in poultry bioaerosols. the objective of this study was to directly compare methanogenic archaea concentrations in bioaerosols f ... | 2012 | 23391229 |
