Antarctic Fungi as a Source of Alternative Antifungal Compounds: Bioactive Metabolites from South Shetland Islands Fungi with Activity Against Candida Species [PDF]

Microorganisms
The emergence of drug-resistant Candida species has intensified efforts to discover novel bioactive compounds. Antarctic environments harbor psychrophilic microorganisms that produce unique secondary metabolites adapted to extreme conditions, making them

Antarctic fungi with antibiotic potential isolated from Fort William Point, Antarctica [PDF]

Scientific Reports, 2022
The Antarctic continent is one of the most inhospitable places on earth, where living creatures, mostly represented by microorganisms, have specific physiological characteristics that allow them to adapt to the extreme environmental conditions.

Antarctic fungi: a bio-source alternative to produce polyunsaturated fatty acids (PUFAs) [PDF]

Microbiology Spectrum
The Antarctic ecosystems are a combination of conditions, including extremely low values of temperature and humidity. Nonetheless, some organisms, such as fungi, can adapt to these extreme conditions.

Climate Change Projected to Double the Richness and Abundance of Soilborne Phytopathogenic Fungi in Southern Maritime Antarctica. [PDF]

Glob Chang Biol
We sequenced fungal DNA in barren soils sampled from 12 sites along a 1900‐km transect through sub‐ and Maritime Antarctica and Patagonia. Using LASSO regression, we found air temperature ‐ and notably mean annual air temperature (BIO1) ‐ to be a highly significant predictor for the richness and relative abundance of soilborne plant pathogens.

Secondary metabolites of Antarctic fungi antagonistic to aquatic pathogenic bacteria [PDF]

Open Life Sciences, 2018
Polar microbial derived antibiotics have potential as alternatives to traditional antibiotics in treating fish against pathogenic bacteria. In this paper, 23 strains of polar fungi were fermented to detect bacteriostatic products on three aquatic ...

Amplicon-Metagenomic Analysis of Fungi from Antarctic Terrestrial Habitats

Frontiers in Microbiology, 2017
In cold environments such as polar regions, microorganisms play important ecological roles, and most of our knowledge about them comes from studies of cultivable microorganisms.

Occurrence of Soil Fungi in Antarctic Pristine Environments

Frontiers in Bioengineering and Biotechnology, 2019
The presence of fungi in pristine Antarctic soils is of particular interest because of the diversity of this microbial group. However, the extreme conditions that coexist in Antarctica produce a strong selective pressure that could lead to the evolution ...

Antimicrobial Peptides Induce Cell Death in Marginal Zone Lymphoma Models Resistant to Targeted Therapies. [PDF]

EJHaem
ABSTRACT Introduction Marginal zone lymphoma (MZL) is an indolent yet incurable B‐cell malignancy in which targeted agents such as BTK and PI3K inhibitors frequently fail due to resistance or toxicity. Antimicrobial peptides (AMPs), evolutionarily conserved effectors of innate immunity, possess selective cytotoxicity against malignant cells by ...
