| quadrisphaera granulorum gen. nov., sp. nov., a gram-positive polyphosphate-accumulating coccus in tetrads or aggregates isolated from aerobic granules. | a gram-positive bacterium, designated strain ag019(t), was isolated by micromanipulation from aerobic granules obtained from a laboratory-scale sequencing batch reactor. this isolate grew axenically as cocci clustered predominantly in tetrads, and was morphologically similar to the dominant organisms observed in the biomass. the morphology also resembled that of the tetrad-forming organisms commonly seen in activated sludge samples. strain ag019(t) was found to be an oxidase-negative, catalase-p ... | 2005 | 16166665 |
| an update of the structure and 16s rrna gene sequence-based definition of higher ranks of the class actinobacteria, with the proposal of two new suborders and four new families and emended descriptions of the existing higher taxa. | the higher ranks of the class actinobacteria were proposed and described in 1997. at each rank, the taxa were delineated from each other solely on the basis of 16s rrna gene sequence phylogenetic clustering and taxon-specific 16s rrna signature nucleotides. in the past 10 years, many novel members have been assigned to this class while, at the same time, some members have been reclassified. the new 16s rrna gene sequence information and the changes in phylogenetic positions of some taxa influenc ... | 2009 | 19244447 |
| pseudokineococcus lusitanus gen. nov., sp. nov., and reclassification of kineococcus marinus lee 2006 as pseudokineococcus marinus comb. nov. | a gram-positive motile coccus shaped actinobacterium, strain t2a-s27(t), was isolated from a roof tile in oporto (portugal) and studied using a polyphasic approach. the 16s rrna gene sequence of the isolate showed high similarity to kineococcus marinus kst3-3(t) (97.8% sequence similarity). lower 16s rrna gene sequence similarities were shown to other members of the genus kineococcus and members of the family kineosporiaceae (<94%). the phylogenetic tree, based on 16s rrna gene sequences, showed ... | 2010 | 21112988 |
