The proteolytic bacterium strain A7P-90mT was isolated from Lake Untersee, Antarctica. The anoxic water was collected from a perennially sealed (~100 millennia) glacial ice lake. Gram-stain-negative cells were 0.18-0.3×8.0-25.0 µm in size, straight, slender rods with unusual gliding motility by external, not previously reported, organelles named here as antiae. At the end of stationary phase of growth, spheroplasts were terminally formed and the cells resembled dandelions. After death, cells were helical...

Landscape-grown foxtail palm (Wodyetia bifurcata A. K. Irvine) trees displaying symptoms of severe foliar chlorosis, stunting, general decline and mortality reminiscent of coconut yellow decline disease were observed in Bangi, Malaysia, during 2012. DNA samples from foliage tissues of 15 symptomatic palms were analysed by employing a nested PCR assay primed by phytoplasma universal ribosomal RNA operon primer pairs, P1/P7 followed by R16F2n/R2. The assay yielded amplicons of a single band of 1.25 kb from DNA samples of 11 symptomatic palms...

Strain ATCC 33076, which produces the antibiotic ramoplanin, was isolated from a soil sample collected in India, and it was classified as a member of the genus Actinoplanes on the basis of morphology and cell-wall composition. A phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain forms a distinct clade within the genus Actinoplanes, and it is most closely related to Actinoplanes deccanensis IFO 13994T (98.71 % similarity) and Actinoplanes atraurantiacus Y16T (98.33 %).

A bacterial strain designated CCM 8645T was isolated from a soil sample collected nearby a mummified seal carcass in the northern part of James Ross Island, Antarctica. The cells were short rods, Gram-stain-negative, non-motile, catalase and oxidase positive, and produced a red-pink pigment on R2A agar. A polyphasic taxonomic approach based on 16S rRNA gene sequencing, extensive biotyping using conventional tests and commercial identification kits and chemotaxonomic analyses were applied to clarify its taxonomic position...
