Repair eXtreme - DNA repair proteins from Antarctic extremophiles
The McMurdo Dry valleys (DV) in Antarctica are one of the harshest environments on Earth, with high levels of UV radiation, freeze-thaw cycles, low moisture, and nutrient content. Bacteria in this extreme environment have adapted to slow growth and low-nutrient conditions. It is proposed that …

USE OF MOLECULAR APPROACHES TO STUDY THE OCCURRENCE OF EXTREMOPHILES AND EXTREMODURES IN NON-EXTREME ENVIRONMENTS
A number of samples were collected from various extreme and non-extreme environments. A range of molecular approaches, in addition to classical microbiology techniques, were used to isolate microorganisms, mainly archaea and bacteria from unusual environments. Halo-bacteria and archaea from …

AcidopHiles : a not- so-basic life
… life forms, however, thrive. They are called extremophiles. 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 …

Prevalence, persistence and consequences of microorganisms within oil field environments and mitigation strategies
… presence of toxic metals). Furthermore, these “extremophiles” can significantly impact oil production operations both negatively (i.e., reservoir souring) and positively (i.e., reservoir souring control). To date, most microbiology studies of hydraulically fractured hydrocarbon reservoirs have …

Phenotypic Switching of Bacterial Cells in Extreme Environments
… and metagenomics of these organisms, also called extremophiles due to their love for extremes of physicochemical conditions. However, these studies only provide a small window into their adaptation. A better insight into their adaptation to these conditions can be obtained by investigating the …

Synthesis of enantio-pure amides by reversal of the Geobacillus pallidus RAPc8 amidase hydrolysis reaction in non-aqueous media
… food industries. The discovery of amidases from extremophiles has increased the potential for application of these enzymes for the development of new processes. In nonaqueous media, amidases have the ability to synthesize enantiopure amides due to the shift in thermodynamic equilibrium towards …

Doctoral Research Project : Sustainable production of bacterial polymers
… step towards commercialising PHAs' use of extremophiles, addressing challenges related to contamination prevention procedures, wastewater treatment costs, and low productivity. To promote environmental sustainability, the study investigated green methods for extracting P(3HB) and …

Characterizing Modified Nucleosides in RNA by LC/UV/MS
… differences among organisms, especially extremophiles that live in harsh conditions, provides clues to how modifications function to enhance structural stability of RNA. RNA modification guides the decoding process in tRNA and organisms of different kingdoms use slightly different …

A technical and economic feasibility study on repurposing copper mine tailings via microbial induced calcium carbonate precipitation
… anaerobic and copper tolerant ureolytic extremophiles contained within, which had the potential to grow more robust bio-columns.

Insights into communities, metabolic and ecological potential of the bacteria of two extreme acidic environments
This work examines the microbial communities in two extremely acidic habitats:the terrestrial environment of the Paint Pots Mound (Kootenay National Park, BritishColumbia, Canada) and the sediments of an ultra-acidic lake in the Smoking Hills (CapeBathurst, Northwest Territories, Canada) area. …

Biotechnologická produkce polyhydroxyalkanoátů pomocí termofilních bakterií
Polyhydroxyalkanoáty (PHA) jsou mikrobiální biopolymery, které mohou představovat částečnou alternativu k petrochemicky vyráběným plastům. Jejich hlavní předností je biodegradabilita, biokompatibilita a možnost produkce z obnovitelných zdrojů. Nicméně náklady na jejich produkci jsou stále vyšší než …
