A Specialized Citric Acid Cycle Requiring Succinyl-Coenzyme A (CoA):Acetate CoA-Transferase (AarC) Confers Acetic Acid Resistance on the Acidophile Acetobacter aceti
The characteristic ability of acetic acid bacteria to aerobically oxidize ethanol to acetic acid has been harnessed for millennia to produce vinegar. Acetic acid permeates cell membranes at low pH and generally inhibits bacterial growth at low millimolar concentrations. The strains used for vinegar …

AcidopHiles : a not- so-basic life
… One subset of extremophile called the acidophile live in acidic environments, at time even more corrosive than battery acid. Acidophiles are microbes, and live together in hugely diverse ecosystems. Each species of acidophile fills a different niche. They survive in high acid …

Studies on Thiobacillus ferrooxidans ATCC 33020 ATP genes and gene products, using Escherichia coli
An atp gene cluster from the extreme acidophile Thiobacillus ferrooxidans ATCC 33020 was cloned by complementation of Escherichia coli unc mutants. Eight different E. coli unc mutants were screened with T. ferrooxidans ATCC 33020 pEcoR251 plasmid and pHC79 cosmid gene banks. The ability of the …

High-power acid Biophotovoltaic cells for the generation of green electricity
… in chapters 4 and 5 explores the extent to which acidophiles may be used as the biological material in MFCs. A search to find a set of naturally-occurring, metallotolerant acidophiles is undertaken throughout the Rio Tinto ecosystem, selected for its unique extreme physicochemical nature and …

Towards bioengineered ecosystems: Three studies in invasion biology
… human environments. Second, experiments with the acidophile Alicyclobacillus acidoterrestris showed that while acid-tolerant invaders exist, the presence of environmental hurdles such as low temperature and high osmolarity are major factors in preventing their establishment in sourdough cultures. …

Scale-up and Measurement Enhancements of a BioGenerator Bioreactor
… the bioreactor. Study into the search for hyperacidophiles thriving in ultra-low pH conditions revealed an interesting finding from the red algae Cyanidium caldarium that was demonstrated to show observable growth to pH -0.85 (19.5% w/w H2SO4), surpassing the current record holders of …

Genome Sequence Analysis and Characterization of Recombinant Enzymes from the Thermoacidophilic Archaeon Picrophilus torridus
Picrophilus torridus ist ein thermo- und acidophiles Archaebacterium, welches mit seinen Wachstumsoptimum bei 60 °C und pH 0,7 den bislang acidophilsten bekannten Organismus repräsentiert. Im Rahmen dieser Arbeit wurde das komplette Genom von P. torridus sequenziert und im Anschluss die …

Etude de l’évolution et caractérisation des milieux semi-naturels des versants du Brabant sablo-limoneux dans le bassin amont de la Dyle : Propositions de mesures de restauration de la lande sèche : Cas de la Grande Bruyère de Rixensart
Au sein du district phytogéographique brabançon, le Brabant sablo-limoneux est caractérisé par une grande diversité de conditions stationnelles. Les versants sont occupés par d’importants affleurements de sables du tertiaire, alternant avec des placages limoneux du quaternaire. Les activités …
