sp. nov., isolated from taro () Free

Abstract

A polyphasic approach was used to characterize an aerobic, Gram-stain-negative, rod-shaped bacterium (designed as strain CC-MHH0539) isolated from the chopped tuber of taro () in Taiwan. Strain CC-MHH0539 was able to grow at 15–30 °C (optimum, 25 °C), at pH 6.0–9.0 (optimum, 7.0) and with 0–1 % (w/v) NaCl. Strain CC-MHH0539 showed highest 16S rRNA gene sequence similarity to LNB2 (96.8 %) 469 (96.5 %), E62-3 (96.4 %) and YC7378 (96.2 %) and <96.1 % similarity to other sphingomonads. Strain CC-MHH0539 was found to cluster mainly with the clade that accommodated members of the genus The dominant cellular fatty acids were C, C 5, C 2-OH, C 7/C 6 and C 7/C 6. Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, two sphingoglycolipids and two unidentified phospholipids were detected in strain CC-MHH0539. The DNA G+C content was 69.5 mol%. The respiratory quinone system and predominant polyamine was ubiquinone 10 (Q-10) and -homospermidine, respectively, which is in line with representatives. Based on the distinct phylogenetic, phenotypic and chemotaxonomic traits, strain CC-MHH0539 is considered to represent a novel species of the genus , for which the name sp. nov. is proposed. The type strain is CC-MHH0539 (=BCRC 80933=JCM 31229).
