“…Likewise, culture-independent studies detected 16S rRNA sequences related to Ignisphaera in a Great Basin spring with pH 7.242 although its abundance was low. Another lineage Sulfophobococcus was previously reported in environments with a pH range of 6.5~8.5 and a low ion strength (<0.2% w/v NaCl)43, however, this lineage was detected in alkaline Tengchong springs with pH ≥ 9. Similarly, Desulfurella , which was considered as a neutrophile44, was found in acidic springs in the present study, co-existing with Hydrogenobaculum and such co-occurrence has been observed in another acidic spring, i.e.…”

“…Dragon spring in Yellowstone National Park (YNP)45. Collectively, these results suggest that some uncultured members within these lineages can tolerate a broader pH range in complex natural environments than in defined culture media3843. Furthermore, microbes in natural environments can be present in micro-environments within sediments or surrounded by their own cell aggregates to avoid unfavorable conditions.…”

Temporal variation in geochemistry can cause changes in microbial community structure and diversity. Here we studied temporal changes of microbial communities in Tengchong hot springs of Yunnan Province, China in response to geochemical variations by using microbial and geochemical data collected in January, June and August of 2011. Greater temporal variations were observed in individual taxa than at the whole community structure level. Water and sediment communities exhibited different temporal variation patterns. Water communities were largely stable across three sampling times and dominated by similar microbial lineages: Hydrogenobaculum in moderate-temperature acidic springs, Sulfolobus in high-temperature acidic springs, and Hydrogenobacter in high-temperature circumneutral to alkaline springs. Sediment communities were more diverse and responsive to changing physicochemical conditions. Most of the sediment communities in January and June were similar to those in waters. However, the August sediment community was more diverse and contained more anaerobic heterotrophs than the January and June: Desulfurella and Acidicaldus in moderate-temperature acidic springs, Ignisphaera and Desulfurococcus in high-temperature acidic springs, the candidate division OP1 and Fervidobacterium in alkaline springs, and Thermus and GAL35 in neutral springs. Temporal variations in physicochemical parameters including temperature, pH, and dissolved organic carbon may have triggered the observed microbial community shifts.

“…The fermentation of polysaccharides and/or peptides has also been noted for other members of the family Desulfurococcaceae, such as Desulfurococcus (Zillig et al, 1982), Thermosphaera (Huber et al, 1998), Staphylothermus (Fiala et al, 1986), Sulfophobococcus (Hensel et al, 1997) and both Acidilobus (Prokofeva et al, 2000) and Caldisphaera (Itoh et al, 2003) of the 'Acidilobus group'. The formation of cell aggregates that was typical of AQ1.S1…”

Consortia containing a novel coccus-shaped, anaerobic heterotroph together with Pyrobaculum rods were cultivated from geothermal environments in New Zealand. Pure cultures of the cocci were only obtained from one such consortium, despite extensive attempts. Cells of this strain (AQ1.S1 T ) were regular to irregular cocci in morphology and occasionally formed large aggregates, especially when utilizing polysaccharides such as konjac glucomannan as a carbon source. Strain AQ1.S1 T is a hyperthermophile, with an optimal temperature for growth between 92 and 95 6C (range 85-98 6C), and a moderate acidophile, with optimal growth occurring at pH 6?4 (range 5?4-7?0). Growth was inhibited by the addition of sulphur and NaCl (optimal growth occurred without addition of NaCl) and an electron acceptor was not required. Strain AQ1.S1T utilized starch, trypticase peptone, lactose, glucose, konjac glucomannan, mannose, galactose, maltose, glycogen and b-cyclodextrin as carbon sources. The G+C content was 52?9 mol%. Based on 16S rRNA gene sequence analysis and physiological features it is proposed that isolate AQ1.S1 T (=DSM 17230represents the type strain of a novel species of a new genus within the Crenarchaeota, Ignisphaera aggregans gen. nov., sp. nov.

“…Thus, growth of most fermentative archaea in closed vessels is either obligately dependent on elemental sulfur or stimulated by its presence. An exception is the fermentation observed with two representatives of the Crenarchaeota, Sulfophobococcus zilligii (Hensel et al, 1997) and Thermosphaera aggregans (Huber et al, 1998), which do not require elemental sulfur and are inhibited by its presence. All members of the genus Desulfurococcus reported to date (Zillig et al, 1982;BonchOsmolovskaya et al, 1988) grow exclusively or preferably on peptides, concomitantly reducing elemental sulfur to H 2 S. Their growth on peptides is stimulated significantly by the presence of elemental sulfur and inhibited by H 2 (Slobodkin & Bonch-Osmolovskaya, 1994 (Pfennig & Lippert, 1965), 1 ml l…”

An obligately anaerobic, hyperthermophilic, organoheterotrophic archaeon, strain Z-1312T, was isolated from a freshwater hot spring of the Uzon caldera (Kamchatka Peninsula, Russia). The cells were regular cocci, 1–4 μm in diameter, with one long flagellum. The cell envelope was composed of a globular layer attached to the cytoplasmic membrane. The temperature range for growth was 63–89 °C, with an optimum between 80 and 82 °C. The pH range for growth at 80 °C was 4·8–6·8, with an optimum at pH 6·0. Strain Z-1312T grew by hydrolysis and/or fermentation of a wide range of polymeric and monomeric substrates, including agarose, amygdalin, arabinose, arbutin, casein hydrolysate, cellulose (filter paper, microcrystalline cellulose, carboxymethyl cellulose), dextran, dulcitol, fructose, lactose, laminarin, lichenan, maltose, pectin, peptone, ribose, starch and sucrose. No growth was detected on glucose, xylose, mannitol or sorbitol. Growth products when sucrose or starch were used as the substrate were acetate, H2 and CO2. Elemental sulfur, thiosulfate and nitrate added as potential electron acceptors for anaerobic respiration did not stimulate growth when tested with starch as the substrate. H2 at 100 % in the gas phase did not inhibit growth on starch or peptone. The G+C content of the DNA was 42·5 mol%. 16S rRNA gene sequence analysis placed the isolated strain Z-1312T as a member of the genus Desulfurococcus, where it represented a novel species, for which the name Desulfurococcus fermentans sp. nov. (type strain Z-1312T=DSM 16532 T=VKM V-2316T) is proposed.
