Ram Hari Dahal, Jaisoo Kim
A novel acidtolerant and alkalitolerant gammaproteobacterium designated strain RS22T was isolated from Kyonggi University forest soil. Cells were aerobic, Gram-staining-negative, catalase- and oxidase- positive, non-motile, non-spore-forming, rod-shaped, and yellow-pigmented. Flexirubin-type pigments were absent. Strain RS22T assimilates lactic acid, L-proline, and 3-hydroxybenzoic acid; tolerates 4 % of NaCl, ferments glucose, and can grow at pH 11.0. A phylogenetic analysis based on its 16S rRNA gene sequence revealed that strain RS22T formed a lineage within the class Gammaproteobacteria of the phylum Proteobacteria that was distinct from various species of the genus Rhodanobacter, including Rhodanobacter denitrificans 2APBS1T (97...

A phosphate-solubilizing bacterium, designated CPCC 100624T, was isolated from a fresh water reservoir in south-west China. The 16S rRNA gene sequence comparison of strain CPCC 100624T with the available sequences in the GenBank database showed that the isolate was closely related to the members of the genus Spirosoma. In the phylogenetic tree based on 16S rRNA gene sequences, strain CPCC 100624T formed a stable phylogenetic subclade with Spirosoma soli MIMBbqt12T within the genus Spirosoma, which indicated that strain CPCC 100624T could be identified as a member of the genus Spirosoma...

Pseudomonas putida is well-known for degradation activities for a variety of compounds and its infections have been reported. Thus, P. putida includes both clinical and nonclinical isolates. To date, no reports have examined the phylogenetic relationship between clinical and nonclinical isolates of the P. putida group. In this study, fifty-nine strains of P. putida group containing twenty-six clinical, and thirty-three nonclinical, isolates, were subjected to phylogenetic and taxonomic analyses based on 16S rRNA gene sequences and nine housekeeping gene sequences, including argS, dnaN, dnaQ, era, gltA, gyrB, ppnK, rpoB, and rpoD, to obtain insights into the diversity of species in this group...

The marine sponge-derived actinomycete, strain ST01-07T, was isolated from Xestospongia sp. collected from the Andaman Sea. The strain was characterised taxonomically by polyphasic approach. The strain contained meso-diaminopimelic acid in the peptidoglycan, whole cell sugars were arabinose, galactose, glucose, mannose, and ribose. Mycolic acids that co-migrated with those from the type strain of Nocardia araoensis NBRC 100135T were observed in whole cell extract. MK-8(H4-cycl) was the predominant menaquinone...

Three strains (14Y260T, 14Y268, and 14Y276) of xylose-assimilating yeasts were isolated from decayed wood and soil collected in West Java in Indonesia. A phylogenetic analysis was performed based on the sequences of the D1/D2 domains of LSU, SSU, and EF-1α, and the three strains were found to represent novel yeast species belonging to genus Pichia. The morphological, biochemical, physiological, and chemotaxonomic characteristics indicated that these strains were distinct from other closely related species...
