Gene Sequence Analysis

An aerobic, Gram-stain-negative, yellow-pigmented, non-motile, rod-shaped bacterium designated strain KMM 9005T was isolated from a sediment sample collected from the Sea of Japan seashore. Comparative 16S rRNA gene sequence analysis showed that strain KMM 9005T belonged to the genus Luteimonas and was most closely related to Luteimonas cucumeris KCTC 23627T (96.5 % sequence similarity) and Luteimonas aquatica LMG 24212T (96.1 % sequence similarity). Strain KMM 9005T was characterized by the presence of thin fimbriae, the major ubiquinone Q-8, by the predominance of iso-C17 : 1 followed by iso-C16 : 0, iso-C15 : 0 and iso-C17 : 0 in its fatty acid profile, weak hydrolytic capacity and the inability to assimilate most organic substrates. Based on these distinctive phenotypic characteristics and phylogenetic analysis, strain KMM 9005T represents a novel species of the genus Luteimonas , for which the name Luteimonas vadosa sp. nov. is proposed. The type strain is KMM 9005T ( = NRIC 0881T = JCM 18392T).

Strains of the recently proposed species Bacteroides chinchillae share more than 99.4 % 16S rRNA gene sequence similarity with the type strain of Bacteroides sartorii although these two species do not appear to be similar from their published descriptions. The aim of this study was to perform phenotypic and genetic analyses of both species to clarify their taxonomic position. B. chinchillae JCM 16497T exhibited high hsp60 gene sequence similarity with B. sartorii JCM 17136T (100 %) as well as B. chinchillae JCM 16498 (100 %). The hsp60 gene sequence analysis and levels of DNA–DNA relatedness observed demonstrated B. sartorii JCM 17136T, B. chinchillae JCM 16497T, and B. chinchillae JCM 16498 are members of a single species. Based on these data, we propose Bacteroides chinchillae as a later heterotypic synonym of Bacteroides sartorii . An emended description of B. sartorii is provided.

A novel actinomycete, designated strain NEAU-GRX6T, was isolated from mucky soil collected from a stream of Jinlong Mountain in Harbin, Heilongjiang Province, north China, and characterized using a polyphasic approach. The isolate formed irregular sporangia containing motile sporangiospores on the substrate mycelium. The whole-cell sugars were xylose, glucose and galactose. The predominant menaquinones were MK-9(H6), MK-10(H4) and MK-9(H4). The major fatty acids were C16 : 0, C15 : 0, C18 : 1ω9c, C17 : 1ω7c and C18 : 0. The phospholipids were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylinositol. The DNA G+C content was 67 mol%. 16S rRNA gene sequence similarity studies showed that strain NEAU-GRX6T belonged to the genus Actinoplanes , being most closely related to Actinoplanes palleronii IFO 14916T (97.80 % similarity) and Actinoplanes missouriensis NBRC 102363T (97.76 %). However, the low observed levels of DNA–DNA relatedness allowed the isolate to be differentiated from the above-mentioned species of the genus Actinoplanes . Moreover, strain NEAU-GRX6T could also be distinguished from A. palleronii IFO 14916T and A. missouriensis NBRC 102363T by phenotypic characteristics. Therefore, it is proposed that strain NEAU-GRX6T represents a novel species of the genus Actinoplanes , for which the name Actinoplanes lutulentus sp. nov. is proposed. The type strain is strain NEAU-GRX6T ( = CGMCC 4.7090T = DSM 45883T).

A beige-coloured, Gram-stain-negative, aerobic, non-motile moderately thermotolerant, rod-shaped organism, strain CC-SPIO-10-1T, was isolated from a coastal hot spring of Green Island (Lutao), located off Taituang, Taiwan, on Marine Agar 2216. Based on 16S rRNA gene sequence analysis, this organism was grouped into the genus Stappia , showing 98.3 % sequence similarity to Stappia indica B106T and 98.2 % gene sequence similarity to Stappia stellulata IAM 12621T . Ubiquinone Q-10 was the major respiratory quinone and C18 : 1ω7c and C18 : 1ω7c 11-methyl were detected as the major fatty acids. The hydroxylated fatty acid C18 : 0 3-OH was detected as well. Predominant polar lipids were diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, unidentified aminolipid AL1 and unidentified phospholipid PL1. Minor amounts of several unidentified lipids (PL2 and L1–L7) were present as well. The polyamine pattern contained the major compounds spermidine and spermine. Strain CC-SPIO-10-1T could be differentiated from the type strains of S. stellulata and S. indica by a set of biochemical tests. On the basis of the 16S rRNA gene sequence analysis and the chemotaxonomic and physiological data, it is concluded that strain CC-SPIO-10T represents a novel species of the genus Stappia for which the name Stappia taiwanensis sp. nov. is proposed. The type strain is CC-SPIO-10 T ( = CCUG 59208T = LMG 25538 T = CCM 7757T).

Six facultatively anaerobic, non-motile lactic acid bacteria were isolated from spontaneous cocoa bean fermentations carried out in Brazil, Ecuador and Malaysia. Phylogenetic analysis revealed that one of these strains, designated M75T, isolated from a Brazilian cocoa bean fermentation, had the highest 16S rRNA gene sequence similarity towards Weissella fabaria LMG 24289T (97.7 %), W. ghanensis LMG 24286T (93.3 %) and W. beninensis LMG 25373T (93.4 %). The remaining lactic acid bacteria isolates, represented by strain M622, showed the highest 16S rRNA gene sequence similarity towards the type strain of Fructobacillus tropaeoli (99.9 %), a recently described species isolated from a flower in South Africa. pheS gene sequence analysis indicated that the former strain represented a novel species, whereas pheS, rpoA and atpA gene sequence analysis indicated that the remaining five strains belonged to F. tropaeoli ; these results were confirmed by DNA–DNA hybridization experiments towards their respective nearest phylogenetic neighbours. Additionally, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry proved successful for the identification of species of the genera Weissella and Fructobacillus and for the recognition of the novel species. We propose to classify strain M75T ( = LMG 26217T  = CCUG 61472T) as the type strain of the novel species Weissella fabalis sp. nov.
