... (mainly soil) washed into the lake produced a more alkaline environment, which excluded some of the acidophilous taxa. Diatom zone II is largely transitional to zone III, which is dominated by Melosira species and includes many indicators of a more eutrophic (nutrient-rich) environment, for example...

... to known fungal lignocellulose degradation genes, including glucanases and xylanases. We conclude that the BSL-adapted taxa Acidomyces , Ochroconis , and Paecilomyces may be promising sources of enzymes that combine heat- and acid-tolerance, potentially valuable in streamlining the pre-treatment...

... (fragilarioid taxa) load positively on axis 1, whereas low species scores are typical of acidophils ( Aulacoseira distans , A. perglabra , Eunotia spp.). The remarkable correspondence between the PCA and WA results indicates (1) that pH is the dominant environmental control over diatom assemblage composition...

... the laminae, and (3) the silicified microbes that dominate some laminae. Identification of silicified microbes can be problematic ( Jones et al., 2001 , 2005 ). Those microbes that can be recognized in terms of extant taxa with a reasonable level of confidence can provide useful paleoecological information...

... of growth medium were prepared for the isolation of microorganisms directly in the subsurface, including: acidophilic S- and Fe-oxidizers (ATCC medium 2039, DSMZ Medium 70, and DSMZ Medium 71) and neutrophilic S-oxidizers (ATCC medium 125). Growth in all medium types was tested and confirmed by molecular...

... in organisms belonging to the animal taxa as well as fungi. It is absent in the prokaryotes, such as the Actinomycetes, which have filaments that resemble mycelia. The presence of chitin in the filamentous microfossils is thus another strong indication that they represent fossilized eukaryotes. In spite of its...

... in methanogens and several recently evolved bacterial taxa. From this perspective, it would be surprising if Nif evolved in any organism other than in an ancestor of the methanogens. The third explanation hinges on the reduction of the inert N≡N triple bond in N 2 having a high activation energy (~200–400 kJ...

Tolm. et Kozhan. could be considered endemic to the ultramafic substrates in the Chukotka region. Species Asplenium viride Huds...

Reactive transport models ( Steefel et al. 2005 ) are now merged with in-silico models and bioinformatics approaches ( King et al. 2009 ) to yield simulations that explain or predict the active microbial taxa...

... focus on neutrophilic iron oxidation. Neutrophilic iron-oxidising organisms are difficult to grow, and this has limited their biological characterisation. It is probable that the pH gradient between the cell interior and the external solution is much reduced compared to that for acidophiles...

....” This bacterium has been the subject of in-depth study of genetic controls on proteins involved in metal reduction (e.g., DiChristina et al., 2002 ). Thiobacillus ferrooxidans , which is an acidophilic iron-oxidizing bacterium, has been shown to greatly increase rates of Fe oxidation (Singer and Stumm, 1970...
