Undibacterium aquatile sp. nov., isolated from a waterfall

Abstract

A Gram-stain-negative, aerobic, motile and rod-shaped strain, THG-DN7.3 T , was isolated from a waterfall. Strain THG-DN7.3T grew well at 18-28 8C and at pH 6.0-7.5 on Reasoner's 2A

Undibacterium arcticum sp. nov., isolated from arctic alpine soil

“…S2). The novel isolate contained phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol as the predominant polar lipids, which is consistent with previous descriptions of species of the genus Undibacterium (K€ ampfer et al, 2007;Eder et al, 2011;Liu et al, 2013;Kim et al, 2014;Du et al, 2015). The polyamine pattern of strain 6-67…”

“…At the time of writing, this genus comprised nine species with validly published names: Undibacterium pigrum (type species; K€ ampfer et al, 2007), U. parvum (K€ ampfer et al, 2007;Eder et al, 2011), U. oligocarboniphilum (Eder et al, 2011), U. terreum (Liu et al, 2013), U. jejuense and U. seohonense (Kim et al, 2014), U. macrobrachii , U. squillarum and U. aquatile (Du et al, 2015). Cells are characteristically Gram-stain-negative, oxidase-positive, rod-shaped, motile by a single polar flagellum and chemoheterotrophic.…”

Undibacterium danionis sp. nov. isolated from a zebrafish (Danio rerio)

“…Additionally, minor amounts of two polar lipids (L1, L2) were present that were not detected after application of specific spray reagents. The polyamine pattern is well in line with that reported for U. macrobrachii (Sheu et al, 2014), U. oligocarboniphilum (Eder et al, 2011) and U. pigrum (K€ ampfer et al, 2007), and a quinone system with ubiquinone Q-8 has been also reported for species of the genus Undibacterium Eder et al, 2011;Kim et al, 2014;Sheu et al, 2014;Du et al, 2016). The major polar lipids phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol have also been reported to be present in Undibacterium aquatile, U. jejuense (Du et al, 2015), U. macrobrachii (Sheu et al, 2014), U. oligocarboniphilum (Eder et al, 2011) and U. pigrum (K€ ampfer et al, 2007).…”

“…Sheu et al (2014). All other data from Du et al (2016). All strains were positive for the following reactions: oxidase, alkaline phosphatase, leucine arylamidase, acid phosphatase, naphthol-AS-BI-phosphohydrolase; negative for the following reactions: assimilation of salicin, melibiose, sorbitol and citrate.…”

“…Data for strains 1 and 2 from this study. Data for strain 2 in parentheses from Sheu et al (2014), all other data from Du et al (2016). Fatty acids amounting to less than 0.5 % in all strains are not listed.…”
