Functional Diversity and Community Composition of Soil Fungi Associated With Canopy Dieback in Araucaria araucana Forests of Contrasting Edaphic Conditions. [PDF]

Environ Microbiol Rep
Soil fungal communities associated with Araucaria araucana differ primarily according to site edaphic conditions rather than tree health status. Restrictive, nutrient‐poor soils are linked to higher canopy dieback and distinct functional community shifts, with symptomatic trees harbouring stress‐tolerant taxa and asymptomatic trees supporting ...

Characterization of the First Cultured Psychrotolerant Representative of Legionella from Antarctica Reveals Its Unique Genome Structure

Microbiology Spectrum, 2021
Culture-independent analysis shows that Legionella spp. inhabit a wide range of low-temperature environments, but to date, no psychrotolerant or psychrophilic strains have been reported.

Microbiological safety of ungulates meat intended to be frozen and defrosting of frozen ungulates meat. [PDF]

EFSA J
Abstract Based on the need for a scientific basis for existing requirements in EU legislation on freezing of meat or for its possible amendment, the opinion compares microbial growth of relevant pathogenic, spoilage and indicator microorganisms within five scenarios of chilling, storage and defrosting of bovine, ovine and porcine meat, using predictive

Enterotoxin Genes, Antibiotic Susceptibility, and Biofilm Formation of Low-Temperature-Tolerant Bacillus cereus Isolated from Green Leaf Lettuce in the Cold Chain

Foods, 2020
The prevalence and characteristics of low-temperature-tolerant Bacillus cereus (psychrotolerant B. cereus) in green leaf lettuce collected during cold chain were investigated. Among the 101 isolated B. cereus samples, only 18 were capable of growth at 7 &

Isolation and Characterization of Phenol-Degrading Psychrotolerant Yeasts [PDF]

Water, Air, & Soil Pollution, 2017
In this study, the potential of selected psychrotolerant yeast strains for phenol biodegradation was studied. From 39 strains isolated from soil and water samples from Rucianka peat bog, three psychrotolerant yeast strains, A011, B021, and L012, showed the ability to degrade phenol.

Selection and Optimization of Medium Components for the Efficient Production of L-Asparaginase by Leucosporidium scottii L115—A Psychrotolerant Yeast

Fermentation, 2022
This study reports the production of L-asparaginase (ASNase), an enzyme mainly used for the treatment of acute lymphoblastic leukemia, by Leucosporidiumscottii L115, a psychrotolerant yeast isolated from the Antarctic ecosystem. Focus was given to select

Physiological and biochemical studies on psychrotolerance in Listeria monocytogenes [PDF]

Journal of Applied Microbiology, 1997
Studies were undertaken to explain the ability of Listeria monocytogenes to grow at low temperatures in a chemostat. It was found that when grown in continuous culture at a dilution rate of 0.02 h-1 L. monocytogenes had a lower proportion of anteiso-17:0, and a higher proportion of anteiso-15:0, and smaller chain fatty acids when grown at 10 degrees C ...

Genome Analysis Reveals Diversity and Functional Potential of Novel Janthinobacterium Species From Subarctic Soils. [PDF]

Microbiologyopen
The Pseudomonadota are abundant and diverse members of high‐latitude soils. Here, we describe two novel species, Janthinobacterium silvisoli and Janthinobacterium saanense, of the order Burkholderiales, isolated from tundra heath and northern boreal forest soils.

Pilot-Scale Cultivation of the Snow Alga Chloromonas typhlos in a Photobioreactor

Frontiers in Bioengineering and Biotechnology, 2022
The most studied and cultivated microalgae have a temperature optimum between 20 and 35°C. This temperature range hampers sustainable microalgae growth in countries with colder periods.
