Paeniglutamicibacter quisquiliarum sp. nov., isolated from midden soil waste

A Gram- stain-positive, irregular short -rod and non-motile bacterium, designated strain ABSL32- 1T, was isolated from a soil sample collected from the Suphan Buri municipal solid waste disposal area. According to the results of a polyphasic taxo-nomic study, a novel species belonging to the genus Paeniglutamicibacter was described. Strain ABSL32- 1T grew optimally at 20-25 degrees C and at pH 6.0-8.0 in the presence of 1 % (w/v) NaCl. The whole -cell sugars were ribose, mannose and glucose. The peptidoglycan structure contained A4 alpha peptidoglycan (Lys-Glu; A11.54). The polar lipids contained digalactosyldiacylglycerol, diphosphatidylglycerol, phosphatidylglycerol, unidentified phospholipids and two unidentified lipids. The major menaquinones were MK -9 and MK-10. The major cellular fatty acid was anteiso- C15: 0 (70.1 %). Based on 16S rRNA gene sequence analysis, strain ABSL32-1T showed the highest similarity to Paeniglutamicibacter sulfureus DSM 20167T (99.5 %), followed by Paeniglutamicibac-ter antarcticus SPC26T (99.0 %) and Paeniglutamicibacter psychrophenolicus AG31T (98.8 %). The genome of strain ABSL32- 1T is 4.4 Mbp with a DNA G+C content of 66.0 mol%. The average nucleotide identity values between strain ABSL32- 1T and the type strains P. sulfureus DSM20167T, P. antarcticus SPC26T and P. psychrophenolicus AG31T were 86.6, 74.7 and 83.6 %, respectively. On the basis of phenotypic, chemotaxonomic and genotypic properties, strain ABSL32- 1T is proposed to represent a novel species to be named Paeniglutamicibacter quisquiliarum sp. nov. The type strain is ABSL32- 1T (=TBRC 14976T=NBRC 115252T).
