  • Flavobacterium aestuarii sp. nov., a novel species isolated from the Pearl River Estuary. Li, Qi Peng, Zi-Qi Wang, Hong-Chuan Dong, Lei Guo, Dan-Yuan Wang, Pan-Deng Luo, Xiao-Qing Luo, Zhen-Hao Yang, Zi-Wen Li, Wen-Jun Phylogeny Flavobacterium RNA, Ribosomal, 16S Estuaries Base Composition Rivers DNA, Bacterial Fatty Acids China Bacterial Typing Techniques Nucleic Acid Hybridization Sequence Analysis, DNA Phospholipids Strain SYSU M80003, a Gram-stain-negative and aerobic bacterium, was isolated from water sample of the Pearl River Estuary, Guangzhou, Guangdong, PR China. The strain could grow at 4-37 °C (optimal: 28 °C), pH 6.0-8.0 (optimal: 7.0), and with 0-1% NaCl (w/v, optimal: 0%). The main fatty acids were anteiso-C, Summed Feature 3 (C ω7c and/or C ω6c) and iso-C. The predominant respiratory quinone was MK-6. The polar lipids contained phosphatidylethanolamine, three unidentified aminolipids, two unidentified aminophospholipids, and two unidentified polar lipids. The genomic DNA G + C content was 35.06%. Phylogenetic analysis based on the 16S rRNA gene revealed that strain SYSU M80003 was closely related to Flavobacterium aquicola JCM 30987 with similarity of 97.28%. Furthermore, the average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between strain SYSU M80003 and F. aquicola JCM 30987 were 83.8% and 28.1%, respectively. Based upon the consensus of phylogenetic and ANI analyses, we conclude that strain SYSU M80003 represents a novel species within the genus Flavobacterium, for which the name Flavobacterium aestuarii sp. nov. is proposed. The type strain is SYSU M80003 (= GDMCC 1.4521 = KCTC 102267).
