ignisphaera aggregans gen. nov., sp. nov., a novel hyperthermophilic crenarchaeote isolated from hot springs in rotorua and tokaanu, new zealand.	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.s1t) 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.s1t is a hyperthermophi ...	2006	16627639
the microbial ecology of a high-temperature near-neutral spring situated in rotorua, new zealand.	a combination of both culture and culture-independent techniques were used to investigate the microbial ecology of a near-neutral, high-temperature hot spring (designated aq1) in rotorua, new zealand. the active microbial members of the community were targeted by analyzing biofilms that developed on surfaces incubated in situ in aq1. colonization of surfaces was rapid as indicated by atp assay and microscopic observation. dna-based analysis of both colonized surfaces and pool water from aq1 reve ...	2008	17207984
complete genome sequence of ignisphaera aggregans type strain (aq1.s1).	ignisphaera aggregans niederberger et al. 2006 is the type and sole species of genus ignisphaera. this archaeal species is characterized by a coccoid-shape and is strictly anaerobic, moderately acidophilic, heterotrophic hyperthermophilic and fermentative. the type strain aq1.s1(t) was isolated from a near neutral, boiling spring in kuirau park, rotorua, new zealand. this is the first completed genome sequence of the genus ignisphaera and the fifth genome (fourth type strain) sequence in the fam ...	2010	21304693
the major lipid cores of the archaeon ignisphaera aggregans: implications for the phylogeny and biosynthesis of glycerol monoalkyl glycerol tetraether isoprenoid lipids.	the lipid cores from ignisphaera aggregans, a hyperthermophilic crenarchaeon recently isolated from new zealand hot springs, have been profiled by liquid chromatography-tandem mass spectrometry. the distribution revealed includes relatively high proportions of monoalkyl (also known as h-shaped) tetraether cores which have previously been implicated as kingdom-specific biomarkers for the euryarchaeota. such high expression of monoalkyl tetraether lipids is unusual in the archaeal domain and may i ...	2011	21630026
