Duganella ginsengisoli sp. nov., isolated from ginseng soil

Abstract

A Gram-stain-negative, rod-shaped bacterium, designated DCY83T , was isolated from soil of a ginseng field in Gwangju Province, Republic of Korea. Cells were motile by means of flagella. Growth occurred at 4-40 8C (optimum 30 8C), at pH 6-8 (optimum pH 7.0) and with j0.4 % NaCl. Strain DCY83 T was able to produce siderophore and was positive for phosphate solubilization. Indole-3-acetic acid production was 12.9 mg ml 21 after 3 days in culture. 16SrRNA gene sequence analysis showed that strain DCY83 T belonged to the genus Duganella

“…Strains FT29W T and FT103W T contained Q-8 as the sole respiratory quinone. This is similar to the respiratory quinone profiles of other members within the family Oxalobacteraceae [23][24][25][26][27]. The cellular fatty acid profiles were homogeneous among strains FT29W T , FT103W T and the six reference strains.…”

“…Strain FT29W T contained less C 10 : 0 3OH than strain FT103W T (0.8 and 4.4 %, respectively). The polar lipids of strain FT103W T consisted of phosphatidylethanolamine, phosphatidylglycerol and one unidentified phospholipid, which was similar to the polar lipid profiles of other members within the family Oxalobacteraceae [23,[25][26][27], but strain FT29W T only contained phosphatidylethanolamine and one unidentified phospholipid (Fig. S4).…”

“…The genus Duganella was proposed by Hiraishi et al in 1997 with the reclassification of Zoogloea ramigera IAM 12670 T (P. R. Dugan 115) [1]. Since then, four novel species within this genus have been reported: Duganella phyllosphaerae T54 T , Duganella ginsengisoli DCY83 T , Duganella sacchari Sac-22 T and Duganella radicis Sac-41 T [2][3][4]. The species within this genus are Gram-strain-negative, rod-shaped and motile with flagella.…”

“…Growth at different pH (4.0-10.5 at 0.5 unit intervals) was tested in R2A broth at 24 °C and the pH values were adjusted using the buffer system as described by Lu et al [22]. Growth at different temperatures (4,10,15,20,24,30,34,37, 40 and 45 °C) was also assessed in R2A broth without NaCl. Catalase activity was tested by observing bubble production by the strain in 3 % (v/v) H 2 O 2 .…”
