isolation of the anaerobic thermoacidophilic crenarchaeote acidilobus saccharovorans sp. nov. and proposal of acidilobales ord. nov., including acidilobaceae fam. nov. and caldisphaeraceae fam. nov.	an anaerobic acidophilic, hyperthermophilic archaeon, designated strain 345-15(t), was isolated from an acidic hot spring of kamchatka (russia). cells of strain 345-15(t) were regular or irregular cocci, 1-2 mum in diameter, with flagella. strain 345-15(t) grew optimally at 80-85 degrees c and ph 3.5-4.0 and fermented a wide range of carbohydrates, including polysaccharides. acetate, ethanol and lactate were the fermentation products. growth was stimulated by elemental sulfur and thiosulfate, wh ...	2009	19643887
isolation, characterization, and ecology of sulfur-respiring crenarchaea inhabiting acid-sulfate-chloride-containing geothermal springs in yellowstone national park.	elemental sulfur (s(0)) is associated with many geochemically diverse hot springs, yet little is known about the phylogeny, physiology, and ecology of the organisms involved in its cycling. here we report the isolation, characterization, and ecology of two novel, s(0)-reducing crenarchaea from an acid geothermal spring referred to as dragon spring. isolate 18u65 grows optimally at 70 to 72 degrees c and at ph 2.5 to 3.0, while isolate 18d70 grows optimally at 81 degrees c and ph 3.0. both isolat ...	2007	17720836
caldisphaera lagunensis gen. nov., sp. nov., a novel thermoacidophilic crenarchaeote isolated from a hot spring at mt maquiling, philippines.	four novel, thermoacidophilic, crenarchaeotic cocci that grew anaerobically and heterotrophically were isolated from an acidic hot spring in the philippines; two representative strains were characterized in detail. most cells were regular cocci, 0.8-1.1 microm in width, which occurred singly or in pairs. they were non-motile and grew at 45-80 degrees c (optimum 70-75 degrees c) and ph 2.3-5.4 (optimum 3.5-4.0). they utilized starch, glycogen, gelatin, beef extract, yeast extract and peptone as c ...	2003	12892143
