Potential of halotolerant and halophilic microorganisms for biotechnology
Halotolerant microorganisms play an essential role in food biotechnology for the production of fermented food and food supplements and the degradation or transformation of a range of organic pollutants and theproduction of alternative energy are other fields of applications of these groups of extremophiles.

Characterization of Hydrocarbon-Degrading Microbial Populations in Contaminated and Pristine Alpine Soils
No correlation was found between the prevalence of hydrocarbon-degradative genotypes and biological activities (respiration, fluorescein diacetate hydrolysis, lipase activity) or numbers of culturable hydrocarbon -degrading soil microorganisms; there also was no correlation between the numbers of hydro carbon degraders and the contamination level. Expand
Diversity and ecology of psychrophilic microorganisms.
Recent knowledge on the abundance, on the taxonomic and functional biodiversity, on low temperature adaptation and on the biogeography of microbial communities in a range of aquatic and terrestrial cold environments are summarized. Expand
Biodegradation and bioremediation of hydrocarbons in extreme environments
Hydrocarbon biodegradation in the presence of high salt concentrations is of interest for the bioremediation of oil-polluted salt marshes and industrial wastewaters, contaminated with aromatic hydrocarbons or with chlorinated hydro carbons. Expand
Monitoring of bioremediation by soil biological activities.
Inorganic nutrients stimulated hydrocarbon biodegradation but not all biological activities to a significant extent, and the residual hydrocarbon content correlated positively with soil respiration, biomass-C (substrate-induced respiration), and with activities of soil dehydrogenase, urease and catalase.

Cold-loving microbes, plants, and animals—fundamental and applied aspects
The mechanisms of microorganisms, plants, and animals to cope with the cold and the resulting biotechnological perspectives are described. Expand
Bioremediation (Natural Attenuation and Biostimulation) of Diesel-Oil-Contaminated Soil in an Alpine Glacier Skiing Area
In the fertilized soil, all biological parameters were significantly enhanced and correlated significantly with each other, as well as with the residual hydrocarbon concentration, pointing to the importance of biodegradation. Expand
Microbial communities and activities in alpine and subalpine soils.
A significant (P<0.05-0.01) increase in the relative amount of culturable psychrophilic heterotrophic bacteria, in therelative amount of the fungal population and in the Relative amount of Gram-negative bacteria was found, which indicates shifts in microbial community composition with altitude.

Bioremediation of diesel-oil-contaminated alpine soils at low temperatures
Abstract Bioremediation of two diesel-oil-contaminated alpine subsoils, differing in soil type and bedrock, was investigated in laboratory experiments at 10 °C after supplementation with an inorganicExpand
