- Abstract
A urea-utilizing bacterium, designated Q2-2
T , was isolated from landfill. Cells of strain Q2-2T were Gram stain-negative, aerobic, short-rod bacteria. Strain Q2-2T was observed to grow at a temperature range of 15–37℃ (optimum 30 ℃), a pH range of 5.5–9.5 (optimum pH 8.0) and 0–4% (w/v) NaCl (optimum 1%). The major respiratory quinone was Q-8, and the major polar lipids were diphosphatidyl glycerol, phosphatidylethanolamine, phosphatidylmethylethanolamine, and phosphatidyl glycerol. Based on the 16S rRNA gene sequence, strain Q2-2T had the highest similarity with Paracandidimonas caeni 24T (98.0%), followed by Pusillimonas soli MJ07T (97.5%), Parapusillimonas granuli Ch07T (97.2%), Pusillimonas ginsengisoli DCY25T (97.1%) and Paracandidimonas soli IMT-305T (96.4%). The ANI values between strain Q2-2T and the above related type strains were 71.02%, 73.52%, 74.32%, 74.59% and 72.29%, respectively. The DNA G + C content of strain Q2-2T was 61.1%. Therefore, strain Q2-2T represents a novel species of the genus Paracandidimonas, for which the name Paracandidimonas lactea sp. nov. (type strain Q2-2T = CGMCC 1.19179T = JCM 34906T ) is proposed.
