The taxonomic positions of Lysobacter species with validly published names and a novel strain Ko07^T, which was newly isolated from an upflow anaerobic sludge blanket reactor treating wastewater from a brewery, were (re)estimated on the basis of results obtained by using a polyphasic taxonomy approach. Phylogenetic inference based on 16S rRNA gene sequences showed that strain Ko07^T and all Lysobacter species with validly published names clustered together in a phylogenetic branch within the class ‘Gammaproteobacteria’. The sequence similarity of strain Ko07^T to the type strains of established Lysobacter species was in the range 94·9–96·7 %. Ubiquinone Q-8 and branched fatty acids, C_{11 : 0} iso, C_{15 : 0} iso, C_{16 : 0} iso, iso C_{17 : 1}9c and C_{11 : 0} iso 3OH, predominantly appeared in strain Ko07^T as well as in all type strains of the recognized Lysobacter species. The DNA–DNA hybridization values of strain Ko07^T with those of recognized Lysobacter species were estimated to be 2–20 %. Despite sharing common taxonomic features in important phenotypic characteristics, such as gliding movement, long-rod shape and proteolytic activity, strain Ko07^T could be distinguished from the Lysobacter species with validly published names by its low DNA–DNA hybridization value, a comparatively low DNA G+C content (63·8 mol%), substrate utilization and some physiochemical characteristics. On the basis of the results obtained in this study, it is proposed that strain Ko07^T should be classified as representing a novel member of the genus Lysobacter, for which the name Lysobacter concretionis sp. nov. is proposed. The type strain is Ko07^T (=KCTC 12205^T=DSM 16239^T).

The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of strain Ko07^T, Lysobacter gummosus ATCC 29489^T and Lysobacter brunescens ATCC 29482^T are AB161359, AB161361 and AB161360, respectively.

16S rRNA gene sequence identity data for strain Ko07^T and closely related bacteria are available as supplementary material in IJSEM Online.
