A Gram-stain-negative, non-motile bacterial strain designated 1NM-4(T) was isolated from an abandoned lead zinc ore mine site in Mei County, Meizhou, Guangdong Province, southern China. The isolate was light yellow, strictly aerobic, oxidase-negative and catalase-positive. Phylogenetic analyses based on 165 rRNA, rpoB and gyrB gene sequences, together with DNA DNA hybridization values less than 70%, revealed that strain 1NM-4(T) belongs to the genus Acinetobacter and may represent a novel species. The major respiratory quinone was ubiquinone 9 (Q-9) and the major cellular fatty acids consisted of C-18:1 omega 9c, summed feature 3 (C-16:1 omega 7c and/or C-16:1 omega 6c), C-16:0 and C-12:0. The major polar lipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, an unidentified aminolipid and two unidentified phospholipids. The genomic DNA G+C content of strain 1NM-4(T) was 47.17 +/- 0.02 mol%. Based on phenotypic, phylogenetic and chemotaxonomic characteristics, strain 1NM-4(T) should be assigned to a novel species of the genus Acinetobacter, for which the name Acinetobacter guangdongensis sp. nov. is proposed. The type strain is 1NM-4(T) (=GIMCC 1.656(T)=CCTCC AB 2014199(T)=KCTC 42012(T)).
