Pedobacter koreensis sp. nov., isolated from fresh water

Abstract

A motile, rod-shaped bacterium, designated strain WPCB189T , was isolated from fresh water collected from the Woopo wetland (Republic of Korea). The cells were found to be Gram-negative, aerobic and catalase-and oxidase-positive. A phylogenetic analysis based on 16S rRNA gene sequences showed that this isolate forms a lineage within the genus Pedobacter, showing sequence similarities of 89.7-96.4 % with respect to recognized species of the genus, and represents a novel member of this genus. The major fatty acids were iso-C 15 : 0 2-OH and/or C 16 : 1 v7c (summed feature 3, 29.7 %), iso-C 15 : 0 (26.4 %) and iso-C 17 : 1 3-OH (10.1 %). The DNA G+C content was 38.0 mol%. On the basis of data obtained from this polyphasic taxonomic study, strain WPCB189 T represents a novel species of the genus Pedobacter, for which the name Pedobacter koreensis sp. nov. is proposed. The type strain is WPCB189 T

“…Many novel species have been recovered from various environments and, at the time of writing, the genus Pedobacter contained 26 recognized species (Steyn et al., 1998;Margesin et al, 2003;Shivaji et al, 2005;Vanparys et al, 2005;Gallego et al, 2006;Hwang et al, 2006; Ten et al, 2006;Baik et al, 2007; Kwon et al, 2007;Muurholm et al, 2007;Yoon et al, 2006Yoon et al, , 2007aAn et al, 2009;Roh et al, 2008;Lee et al, 2009). The description of the genus Pedobacter has also been emended recently (Vanparys et al, 2005;Gallego et al, 2006;Hwang et al, 2006).…”

“…At the time of writing, the genus Pedobacter comprises 46 species with validly published names, with a rapid increase in number since 2006. The majority of these species were isolated from soil (Steyn et al, 1998;Ten et al, 2006;Yoon et al, 2006Yoon et al, , 2007aRoh et al, 2008;Gordon et al, 2009;Jeon et al, 2009;Zhang et al, 2010;Luo et al, 2010;Zhou et al, 2012;Jung et al, 2012;Hoang et al, 2013;Yang et al, 2013;Oh et al, 2013;Margesin & Zhang, 2013;Kook et al, 2014) and water (Gallego et al, 2006;Hwang et al, 2006;Baik et al, 2007;Muurholm et al, 2007;Asker et al, 2008;Urios et al, 2013), and the others were collected from glaciers (Margesin et al, 2003;Shivaji et al, 2005;Qiu et al, 2014), a nitrifying inoculum (Vanparys et al, 2005), the plant rhizosphere (Kwon et al, 2007(Kwon et al, , 2011, compost (Lee et al, 2009), sediment Gordon et al, 2009) and chilled food (Derichs et al, 2014). Members of the genus Pedobacter are aerobic, non-spore-forming, rod-shaped, Gram-stain-negative bacteria positive for catalase and oxidase reactions and negative for gelatinase, urease, indole production and nitrate reduction (Zhou et al, 2012).…”
