Flavobacterium nakdongensis sp. nov., Isolated from Fresh Water during the Cyanobacterial Bloom Period.
A novel Gram-negative bacterial strain, 20NA77.7T, was isolated from fresh water of the Nakdong River. Strain 20NA77.7T shared the highest similarity with Flavobacterium indicum GPTSA100-9T (97.91%) and Flavobacterium urocaniciphilum DSM 27078T (96.24%) in the 16S rRNA gene sequence. The digital DNA-DNA hybridization and average nucleotide identity values for strain 20NA77.7T with Flavobacterium species were below 20.8% and 77.33%, respectively. The major fatty acids of strain 20NA77.7T were identified as iso-C15:0, iso-C16:0, iso-C15:1 G, anteiso-C15:0, iso-C15:0 3OH, and iso-C16:0 3OH. Strain 20NA77.7T contained phosphatidylethanolamine, one unidentified aminolipid, and three unidentified lipids as polar lipids and menaquinone-6 as menaquinone. The polyphasic evidence supports the classification of strain 20NA77.7T as a novel species belonging to the genus Flavobacterium, for which the name Flavobacterium nakdongensis is proposed. The type strain is 20NA77.7T (= KCTC 102000T = LMG 33137T).
期刊介绍：
The Journal of Microbiology and Biotechnology (JMB) is a monthly international journal devoted to the advancement and dissemination of scientific knowledge pertaining to microbiology, biotechnology, and related academic disciplines. It covers various scientific and technological aspects of Molecular and Cellular Microbiology, Environmental Microbiology and Biotechnology, Food Biotechnology, and Biotechnology and Bioengineering (subcategories are listed below). Launched in March 1991, the JMB is published by the Korean Society for Microbiology and Biotechnology (KMB) and distributed worldwide.
