Three forest and four botanical garden top soil isolates with unique MALDI-TOF mass spectra were identified as Paraburkholderia strains closely related to Paraburkholderia sartisoli through recA gene sequence analysis. OrthoANIu, digital DNA-DNA hybridization analyses and phylogenomic analyses demonstrated that the five strains represented two new Paraburkholderia species closely related to P. sartisoli. The genome of strain LMG 31841T had a cumulative size of 6.3 Mb and a G + C content of 62.64 mol%; strain LMG 32171T had a genome size of 5.8 Mb and a G + C content of 62.91 mol%. Hemolysis on horse blood agar, beta-galactosidase and phosphoamidase activity, and assimilation of adipic acid and trisodium citrate allowed phenotypic differentiation of strains LMG 31841T, LMG 32171T and P. sartisoli LMG 24000T. An analysis of the genomic potential for aromatic compound degradation yielded additional differences among strains representing these three species, but also highlighted some discrepancies between the presence of genes and pathways, and the phenotype revealed through growth experiments using a mineral salts medium supplemented with single aromatic compounds as carbon sources. We propose to classify all isolates from the present study into two novel Paraburkholderia species, for which we propose the names Paraburkholderia gardini with LMG 32171T (=CECT 30344T) as the type strain, and Paraburkholderia saeva with LMG 31841T (=CECT 30338T) as the type strain.

UI MeSH Term Description Entries
D009693 Nucleic Acid Hybridization Widely used technique which exploits the ability of complementary sequences in single-stranded DNAs or RNAs to pair with each other to form a double helix. Hybridization can take place between two complimentary DNA sequences, between a single-stranded DNA and a complementary RNA, or between two RNA sequences. The technique is used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.
