Abstract

A novel predatory bacterium, strain LBG001, has been isolated from Reynosa, Mexico. The 16S rRNA shares approximately 97 % sequence identity with many reported strains in the genus including the type strain HD100. Phylogenetic trees based on the 16S rRNA gene and on 30 concatenated housekeeping genes or core genes showed that LBG001 is on a separate branch from the group. LBG0001 has a genome size of 3 582 323 bp with a G+C content of 43.1 mol %. The average nucleotide identity, average amino acid identity and digital DNA–DNA hybridization values with other members of the genus (<79, <72 and <17 %, respectively) qualifies the strain to represent a new species in the genus. Strain LBG001 formed visible plaques on all 10 tested Gram-negative bacterial species. The phenotypic characteristics, phylogenetic analysis and genomic taxonomic studies support the classification of the strain as representing a new species for which the name sp. nov. is proposed. The type strain is LBG001(=ATCC TSD-288 CM-CNRG 0932).
