Soot biodegradation by psychrotolerant bacterial consortia

Biodegradation, 2022
To probe the bioavailability of soot released into the atmosphere is pivotal to understanding their environmental impacts. Soot aerosol absorbs organic matter, creating a hot spot for biogeochemical transformation and the global carbon cycle. Soot primarily contains condensed aromatics chemically recalcitrant; however, oligotrophic microorganisms might

Characterization of psychrotolerant heterotrophic bacteria from Finnish Lapland

Systematic and Applied Microbiology, 2006
A total of 331 aerobic heterotrophic bacterial strains were isolated from various ecosystems of Finnish Lapland (68-69 degrees N) including forest soil, arctic alpine-tundra soil, stream water, lake and mire sediments, lichen and snow algae. Whole cell fatty acid and 16S rRNA gene sequence analysis and microscopy indicated that the isolates were ...

[Consumption of hydrocarbons by psychrotolerant degrader strains].

Prikladnaia biokhimiia i mikrobiologiia, 2007
Oil-oxidizing microorganisms have been sampled in various regions of Siberia and used in strain associations, which degrade n-alkanes of oil from various fields by 64-92% after 6 days of growth in a wide temperature range. These strains are salt-tolerant and psychrotolerant. They are compatible with aboriginal soil microflora.

Occurrence of psychrotolerant Bacillus cereus group strains in ice creams

International Journal of Food Microbiology, 2010
The occurrences of Bacillus cereus group strains in 40 ice cream samples were investigated. Among 109 isolated B. cereus group strains confirmed by 16S rDNA sequence analysis only 50 were identified as B. cereus and one as B. thuringiensis by using FDA (U.S. Food and Drug Administration) standard, indicating the two identification standards were highly

Psychrophilic and Psychrotolerant Yeasts

Cold habitats, defined by temperatures below 5 °C, cover much of the Earth and are vital for microbial diversity, particularly psychrophilic (cold-loving) and psychrotolerant (cold-tolerant) yeasts. These habitats, once thought lifeless, play key roles in biogeochemical cycles.

Culturable psychrotolerant methanotrophic bacteria in landfill cover soil

Microbiology, 2013
Methanotrophs closely related to psychrotolerant members of the genera Methylobacter and Methylocella were identified in cultures enriched at 10@C from landfill cover soil samples collected in the period from April to November. Mesophilic methanotrophs of the genera Methylobacter and Methylosinus were found in cultures enriched at 20 degrees C from the

Anhydrobiosis in yeasts: Psychrotolerant yeasts are highly resistant to dehydration

Yeast, 2019
AbstractYeast cells are able to transition into a state of anhydrobiosis (temporary reversible suspension of metabolism) under conditions of desiccation. One of the most efficient approaches for understanding the mechanisms underlying resistance to dehydration–rehydration is to identify yeasts, which are stable under such treatments, and compare them ...

Psychrotolerant actinomycetes in soils of the tundra and northern taiga

Moscow University Soil Science Bulletin, 2011
Actinomycetes adapted to low-temperature conditions are present in the cold soils of the tundra and northern taiga in quantities comparable to mesophylic forms and dominate in the soil actinomycete complex. Actinomycetes isolated from cold soils were identified as Streptomyces.

[Taxonomical status of the psychrotolerant Antarctic microorganisms].

Mikrobiolohichnyi zhurnal (Kiev, Ukraine : 1993), 2014
The aerobic chemoorganotrophic bacteria, dominating in soils and phytocenosis of the Antarctic Region, on combination of morphological and biochemical properties belong to several taxons of Bacteria domain. Gram-negative strains 3189, 3415 (fam. Halomonadaceae, Halomonas sp.) and 3088, 3468, 3469 (fam. Moraxellaceae, Psychrobacter sp.) belong to phylum

Ecophysiology of psychrophilic and psychrotolerant microorganisms.

Cellular and molecular biology (Noisy-le-Grand, France), 2005
This review describes psychrophilic and psychrotolerant microorganisms, which are abundant in different kinds of environments. Their ecophysiological properties and strategies for survival are reviewed in relation to their occurrences in marine and terrestrial environments, with special reference to the deep-sea, the sea ice and the permafrost soils.
