Emended description of the family Chromatiaceae, phylogenetic analyses of the genera Alishewanella, Rheinheimera and Arsukibacterium, transfer of Rheinheimera longhuensis LH2-2T to the genus Alishewanella and description of Alishewanella alkalitolerans sp. nov. from Lonar Lake, India.

Phylogenetic analyses were performed for members of the family Chromatiaceae, signature nucleotides deduced and the genus Alishewanella transferred to Chromatiaceae. Phylogenetic analyses were executed for the genera Alishewanella, Arsukibacterium and Rheinheimera and the genus Rheinheimera is proposed to be split, with the creation of the Pararheinheimera gen. nov. Furthermore, the species Rheinheimera longhuensis, is transferred to the genus Alishewanella as Alishewanella longhuensis comb. nov. Besides, the genera Alishewanella and Rheinheimera are also emended. Strain LNK-7.1T was isolated from a water sample from the Lonar Lake, India. Cells were Gram-negative, motile rods, positive for catalase, oxidase, phosphatase, contained C16:0, C17:1�s8c, summed feature3 (C16:1�s6c and/or C16:1�s7c) and summed feature 8 (C18:1�s7c) as major fatty acids, PE and PG as the major lipids and Q-8 as the sole respiratory quinone. Phylogenetic analyses using NJ, ME, ML and Maximum parsimony, based on 16S rRNA gene sequences, identified Alishewanella tabrizica RCRI4T as the closely related species of strain LNK-7.1T with a 16S rRNA gene sequence similarity of 98.13%. The DNA-DNA similarity between LNK-7.1T and the closely related species (A. tabrizica) was only 12.0% and, therefore, strain LNK-7.1T was identified as a novel species of the genus Alishewanella with the proposed name Alishewanella alkalitolerans sp. nov. In addition phenotypic characteristics confirmed the species status to strain LNK-7.1T. The type strain of A. alkalitolerans is LNK-7.1T (LMG 29592T = KCTC 52279T), isolated from a water sample collected from the Lonar lake, India.

Rheinheimera tilapiae sp. nov., isolated from a freshwater culture pond.
PMID : 22843724 DOI : 10.1099/ijs.0.043836-0
A bacterial strain designated Ruye-90(T) was isolated from a freshwater tilapiine cichlid fish culture pond in Taiwan and characterized using a polyphasic taxonomic approach. Strain Ruye-90(T) was gram-negative, aerobic, yellow-coloured, rod-shaped, and motile by means of a single polar flagellum. Growth occurred at 4-30 �XC (optimum, 20-30 �XC), at pH 7.0-9.0 (optimum, pH 8.0-9.0) and with 0-2 % NaCl (optimum, 0 %). Phylogenetic analyses based on 16S rRNA gene sequences showed that strain Ruye-90(T) belonged to the genus Rheinheimera and its most closely related neighbour was Rheinheimera tangshanensis JA3-B52(T) with sequence similarity of 97.5 %. The major fatty acids were summed feature 3 (comprising C16 : 1�s7c and/or C16 : 1�s6c, 41.3 %), C16 : 0 (19.3 %), C18 : 1�s7c (8.4 %) and C12 : 0 3-OH (7.0 %). The major respiratory quinone was Q-8. The DNA G+C content of the genomic DNA was 49.0 mol%. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylserine, aminolipid and two uncharacterized phospholipids. The DNA-DNA relatedness of strain Ruye-90(T) with respect to recognized members of the genus Rheinheimera was less than 70 %. On the basis of the genotypic, chemotaxonomic and phenotypic data, strain Ruye-90(T) represents a novel species in the genus Rheinheimera, for which the name Rheinheimera tilapiae sp. nov. is proposed. The type strain is Ruye-90(T) (= LMG 26339(T) = BCRC 80263(T) = KCTC 23315(T)).
