Pontibacter korlensis sp. nov., isolated from the desert of Xinjiang, China

Abstract

Two Gram-negative, rod-shaped, gliding and pink-pigmented bacterial strains, X14-1 T and X19-1, were isolated from a mixture of sand samples collected from the desert of Xinjiang, China, and characterized by using a polyphasic taxonomic approach. Strains X14-1 T and X19-1 contained MK-7 as the predominant menaquinone. The major cellular fatty acids included iso-C 15 : 0 , iso-C 17 : 0 3-OH, summed feature 3 and summed feature 4.

Pontibacter niistensis sp. nov., isolated from forest soil

“…Nedashkovskaya et al (2005), Zhou et al (2007), Zhang et al (2008), Wang et al (2010), Suresh et al (2006) and this study and were obtained under identical growth conditions except for data in columns 5 and 6. +, Positive; 2, negative; ND, no data available.…”

“…At the time of writing, the genus Pontibacter comprises five species with validly published names: Pontibacter actiniarum, the type species (Nedashkovskaya et al, 2005), Pontibacter akesuensis, Pontibacter korlensis and Pontibacter xinjiangensis (Zhou et al, 2007;Zhang et al 2008;Wang et al, 2010) and Pontibacter roseus, resulting from the recent reclassification of Effluviibacter roseus (Suresh et al, 2006;Wang et al, 2010). The type strains of recognized species of the genus are Gram-negative, aerobic, heterotrophic, pink-pigmented bacteria and have been isolated from a marine actinian, desert soil, other soils and muddy water.…”

Pontibacter amylolyticus sp. nov., isolated from a deep-sea sediment hydrothermal vent field

“…At the time of writing, the genus Pontibacter comprised 20 species with validly published names. Members of the genus Pontibacter have been isolated from an actinian (Nedashkovskaya et al, 2005), seawater (Kang et al, 2013), a solar saltern (Subhash et al, 2013), a drainage system (Suresh et al, 2006), soils (Dastager et al, 2010;Wang et al, 2010;Xu et al, 2012;Cao et al, 2014;Dai et al, 2014;Srinivasan et al, 2014), hexachlorocyclohexanecontaminated soils (Dwivedi et al, 2013;Singh et al, 2013Singh et al, , 2014Singh et al, , 2015, and desert soils or sands Zhang et al, 2008Zhang et al, , 2013Subhash et al, 2014;Xu et al, 2014). Three additional species, 'Pontibacter salisaro' (Joung et al, 2011), 'Pontibacter rhizosphera' (Raichand et al, 2011) and 'Pontibacter jeungdoensis' (Joung et al, 2013) have been described; however, the names had not validly published as of September 2015.…”

Pontibacter mucosus sp. nov., isolated from hexachlorocyclohexane-contaminated pond sediment

“…The species belonging to the genus Pontibacter are Gram-stain-negative, heterotrophic, aerobic, rod-shaped, motile by means of gliding or nonmotile, have MK-7 (menaquinone 7) as the predominant respiratory quinone and phosphatidylethanolamine as the major polar lipid. At the time of writing, 24 species of the genus Pontibacter have been isolated and classified from diverse niches such as desert soils, muddy water, seawater, hexachlorocyclohexane (HCH)-contaminated soil and pond sediments, forest soils, solar salterns, mountain soils, rhizosphere soils and also from marine actinians (Nedashkovskaya et al, 2005;Suresh et al, 2006;Zhou et al, 2007;Zhang et al, 2008;Dastager et al, 2010;Raichand et al, 2011;Xu et al, 2012;Dwivedi et al, 2013;Kang et al, 2013;Subhash et al, 2013Subhash et al, , 2014Singh et al, 2014Singh et al, , 2015Srinivasan et al, 2014;Mahato et al, 2015). However, out of the 24 known species of the genus Pontibacter, the names of three species, namely 'Pontibacter salisaro' (Joung et al, 2011), 'Pontibacter jeungdoensis' and 'Pontibacter rhizosphera' (Raichand et al, 2011), have yet to be validly published according to the List of Prokaryotic names with Standing in Nomenclature (http://www.…”
