Cells of the strain were aerobic, short rod or coccoid, Gram-stain-negative and non-motile. Colonies of the strain were initially transparent but with time changed to a creamy white colour. Phylogenetic analysis based on the 16S rRNA marker gene showed that it was closely associated with Paracoccus aestuariivivens GHD-30T (99.1 %) and Paracoccus limosus NB88T (98.0 %), followed by Paracoccus laeviglucosivorans 43PT (97.9 %) and Paracoccus marinus KKL-A5T (97.0 %). The DNA–DNA hybridization values of strain LP91T with the closely related type strains mentioned above were below 51.2±0.64 %, confirming it as a distinct species from other known species of the genus Paracoccus . The major cellular fatty acids of strain LP91T were C18 : 0 ω7c/C18  : 0 ω6c and C16 : 0. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine and aminophospholipid, along with other lipids including glycolipids, aminolipids and other unknown phosphoglycolipids. Spermine was the major polyamine, along with putrescine in a minor amount. Ubiquinone (Q-10) was the sole isoprenoid quinone. Based on the results of phylogenetic, phenotypic and chemotaxonomic analysis, it is proposed that the isolate represents a new species of the genus Paracoccus , for which the name Paracoccus sordidisoli sp. nov. is proposed. The type strain is LP91T (=KCTC 42938T=CCM 8696T=MCC 3128T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.002289
