چکیده

A novel thermophilic and endospore-forming Gram-positive bacterium capable of assimilating and isomerizing l-ribose was isolated from a volcanic area in Likupang, Indonesia. The isolate, RI-39(T), was able to grow at high temperatures (37-60 degrees C); optimum growth was observed at pH 6.5 and 45 degrees C. The strain contained MK-7 (87 %) as the main respiratory quinone and had a DNA G+C content of 51 mol%. The major cellular fatty acids of the isolate were iso-C(16 : 0) and anteiso-C(15 : 0) and the predominant polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and lysyl-phosphatidylglycerol. Phylogenetic analysis based on 16S rRNA gene sequences revealed that the isolate represents an evolutionary lineage that is distinct from those of other Cohnella species. Based on morphological, physiological and chemotaxonomic characteristics and 16S rRNA gene sequence comparisons, it is proposed that strain RI-39(T) represents a novel species, Cohnella laeviribosi sp. nov. The type strain is RI-39(T) (=KCTC 3987(T) =KCCM 10653P(T) =CCUG 52217(T)).

Cohnella luojiensis sp. nov., isolated from soil of a Euphrates poplar forest.

A novel strain, HY-22R(T), was isolated from soil of a Euphrates poplar forest in Xinjiang, China. The cells were Gram-positive-staining, rod-shaped and motile by means of peritrichous flagella. Growth occurred at 10-37 degrees C (optimum 30 degrees C), at pH 7.0-8.0 (optimum pH 7.0) and with 0-1 % NaCl. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain HY-22R(T) was...

A bacterial strain designated RLAHU4B(T) was isolated from root nodules of Lupinus albus in León (Spain). The 16S rRNA gene sequence of this strain showed similarities lower than 97 % with respect to species of the genus Cohnella. The strain was a Gram-variable, sporulating rod, motile by means of peritrichous flagella, and facultatively anaerobic. It was positive for oxidase, catalase and β-ga...

A new species of the Andean-Patagonian Liolaemus elongatus clade is described. Liolaemus crandalli sp. nov. differs from other members of its clade by a combination of coloration characters, scale counts and genetic traits. Liolaemus crandalli sp. nov. is known only from an isolated volcanic mountain in northwestern Patagonia above 1500 m.a.s.l. unconnected with other habitat suitable for speci...
