( 2012 ) Azospirillum formosense sp. nov., a diazotroph from agricultural soil. PMID : 21742820 DOI : 10.1099/ijs.0.030585-0 DOI : 10.1099/ijs.0.030585-0 Abstract >>
A gram-negative, spiral or rod-shaped, non-spore-forming diazotrophic bacterium, designated CC-Nfb-7(T), was isolated from agricultural soil in Yunlin County, Taiwan. 16S rRNA gene sequence analysis showed that strain CC-Nfb-7(T) was most closely related to Azospirillum brasilense DSM 1690(T) (97.4 % 16S rRNA gene sequence similarity), Azospirillum rugosum IMMIB AFH-6(T) (96.8 %) and Azospirillum oryzae JCM 21588(T) (96.6 %); <96.5 % 16S rRNA gene sequence similarity was found with all other members of the genus Azospirillum. DNA-DNA relatedness between strain CC-Nfb-7(T) and A. brasilense DSM 1690(T), A. rugosum DSM 19657(T) and A. oryzae JCM 21588(T) was 38.9, 30.1 and 31.8 %, respectively. The respiratory quinone was ubiquinone Q-10. The major fatty acids were summed feature 8 (consisting of C(18 : 1)�s7c and/or C(18 : 1)�s6c), summed feature 3 (consisting of C(16 : 1)�s7c and/or C(16 : 1)�s6c), summed feature 2 (consisting of C(14 : 0) 3-OH and/or iso-C(16 : 1) I), C(16 : 0), C(18 : 0) 2-OH and C(16 : 0) 3-OH. The polar lipids consisted mainly of phosphatidylglycerol, phosphatidylcholine and one unidentified phospholipid. Furthermore, moderate amounts of phosphatidylethanolamine, phosphatidyldimethylethanolamine and one unidentified aminophospholipid were also detected. Strain CC-Nfb-7(T) could be distinguished from members of phylogenetically related species by differences in phenotypic properties. On the basis of morphological, chemotaxonomic and phylogenetic data, strain CC-Nfb-7(T) represents a novel species within the genus Azospirillum, for which we propose the name Azospirillum formosense sp. nov. The type strain is CC-Nfb-7(T) (= BCRC 80273(T) = JCM 17639(T) = DSM 24137(T)).

( 2013 ) Chiayiivirga flava gen. nov., sp. nov., a novel bacterium of the family Xanthomonadaceae isolated from an agricultural soil, and emended description of the genus Dokdonella. PMID : 23475342 DOI : 10.1099/ijs.0.048579-0 Abstract >>
A novel Gram-reaction-negative, yellow-pigmented, aerobic, non-motile and rod-shaped bacterium designated strain CC-YHH031(T) was isolated from an agricultural soil collected at Chiayi County, Taiwan. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CC-YHH031(T) formed a discrete monophyletic lineage in the family Xanthomonadaceae, sharing high pairwise sequence similarity of 93.5-95.2 and 94.8% with species of the genus Dokdonella (94.9% similarity to the type strain of the type species) and Aquimonas voraii GPTSA 20(T), respectively. The genomic DNA G+C content of strain CC-YHH031(T) was 68.6 �� 0.7 mol% and the predominant respiratory quinone was ubiquinone Q-8. Spermidine was the principal polyamine, with minor amounts of putrescine. Major fatty acids (>5% of total fatty acids) were iso-C(16:00, iso-C(15:0), C(16:1)�s7c and/or C(16:1)�s6c (summed feature 3), iso-C(17:1)�s9c, iso-C(14:0), iso-C(11:0) and iso-C(11:0) 3-OH. The polar lipid profile of strain CC-YHH031(T) included phosphatidylethanolamine, phosphatidylmonomethylethanolamine, diphosphatidylglycerol, phosphatidylglycerol, two unidentified aminophospholipids (APL1-2) and four unidentified phospholipids (PL1-4). Strain CC-YHH031(T) was distinguished particularly from the type species of the genus Dokdonella (Dokdonella koreensis) by the presence of major amounts of iso-C(14:0) and summed feature 3 and minor amounts of iso-C(17:0) and by the complete absence of anteiso-C(17:0), the presence of PL1-3 and APL1-2, the absence of APL3 and the presence of putrescine in the former. On the basis of distinguishing genotypic and phenotypic evidence, strain CC-YHH031(T) is proposed to represent a novel genus and species within the family Xanthomonadaceae, for which the name Chiayiivirga flava gen. nov., sp. nov. is proposed. The type strain of Chiayiivirga flava is CC-YHH031(T) (=BCRC 80273(T) =DSM 24163(T)).
