摘要： A Gram-stain-negative, motile, rod-shaped bacterium, designated strain LAM2020(T), was isolated from a sulfonylurea herbicides-degrading bacterial consortium. The optimal temperature and pH for the growth of strain LAM2020(T) were 30 degrees C and 7.0, respectively. Strain LAM2020(T) formed a distinct phylogenetic subclade within the genus Cedecea in the phylogenetic trees built with 16S rRNA gene sequences and shared the highest similarity with Cedecea davisae DSM 4568(T) (98.4%). The values of digital DNA-DNA hybridization and average nucleotide identity (ANI) based on the genome sequences between LAM2020(T) and C. davisae DSM 4568(T) were 22.7% and 80.0%, respectively. It contained 54.0 mol% of G+C in the genomic DNA. The major cellular fatty acids of strain LAM2020(T) were summed feature 3 (C-16:1 omega 6c and/or C-16:1 omega 7c), C-16:0 and summed feature 8 (C-18:1 omega 7c/C-18:1 omega 6c). The major polar lipids present in strain LAM2020(T) were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and aminophospholipid. The respiratory quinone of strain LAM2020(T) was ubiquinone-8 and ubiquinone-7. Based on the phenotypic characteristics, chemotaxonomic data and genotypic analyses, strain LAM2020(T) should be classified as a novel species of genus Cedecea, for which the name Cedecea sulfonylureivorans sp. nov. is proposed. The type strain is LAM2020(T) (=GDMCC 1.2363(T)=JCM 34640(T)).
