Yellowish Orange

A Gram-reaction-negative, aerobic, yellowish-orange-pigmented bacterial strain, designated JC2436T, was isolated from tidal-flat sediment of Oi Island in Korea. Comparative 16S rRNA gene sequence analysis indicated its close affiliation to Vitellibacter vladivostokensis, with 96 % sequence similarity to the type strain. Cells grew with 2–6 % NaCl and at 10–41 °C. Orange flexirubin pigments were present. The major isoprenoid quinone was MK-6, the DNA G+C content was 48.7 mol% and the predominant fatty acids (>10 %) were iso-C15 : 0 and iso-C17 : 0 3-OH. The data obtained from this polyphasic study support the classification of this isolate within a novel species in the genus Vitellibacter, for which the name Vitellibacter aestuarii sp. nov. is proposed. The type strain is JC2436T (=IMSNU 14137T =KACC 13727T =KCTC 22361T =JCM 15496T).

Iucn Criteria

An emended description of the poorly known Begonia serotina A.DC. (Begoniaceae) is provided and B. asympeltata L.B.Sm. & Wassh. is newly synonymised with that species. The classification of Begonia serotina in B. sect. Knesebeckia (Klotzsch) A.DC. is confirmed. Begonia compacticaulis Irmsch. is shown to be a synonym of B. ludwigii Irmsch., while the circumscription of B. compacticaulis in the Flora of Ecuador is shown to be based on specimens of both B. ludwigii and B. serotina. Begonia serotina is more widely distributed than previously recorded and is newly reported from Ecuador’s Los Rios, Bolivar and Loja provinces and Peru’s Tumbes region. Begonia serotina is reassessed as Vulnerable (VU), according to IUCN criteria.

Close Relationship

16S rRNA gene sequence information has indicated that Xylanibacter oryzae has a close relationship with the genus Prevotella . To clarify the taxonomic position of X. oryzae , we determined the sequence of hsp60 as it represents an alternative phylogenetic marker for identification and classification of Gram-negative anaerobic rods. On the basis of hsp60 sequences, X. oryzae was located within the genus Prevotella , indicating that the species does not represent a distinct taxon at the genus level. Statistical tests (the Shimodaira–Hasegawa test and the approximately unbiased test) supported the finding that X. oryzae is monophyletic with members of the genus Prevotella and thus belongs to the genus. On the basis of the phylogenetic findings, we propose that X. oryzae should be reclassified as Prevotella oryzae comb. nov.; the type strain is KB3T ( = JCM 13648T  = DSM 17970T). An emended description of the genus Prevotella is also provided.
