Isolation by Miniaturized Culture Chip of an Antarctic bacterium Aequorivita sp. with antimicrobial and anthelmintic activity

open access: yesBiotechnology Reports, 2018
Microbes are prolific sources of bioactive molecules; however, the cultivability issue has severely hampered access to microbial diversity. Novel secondary metabolites from as-yet-unknown or atypical microorganisms from extreme environments have ...

Microbial Community Structure Driven by a Volcanic Gradient in Glaciers of the Antarctic Archipelago South Shetland

open access: yesMicroorganisms, 2021
It has been demonstrated that the englacial ecosystem in volcanic environments is inhabited by active bacteria. To know whether this result could be extrapolated to other Antarctic glaciers and to study the populations of microeukaryotes in addition to ...

Microbiology: lessons from a first attempt at Lake Ellsworth [PDF]

open access: yes, 2015
During the attempt to directly access, measure and sample Subglacial Lake Ellsworth in 2012–2013, we conducted microbiological analyses of the drilling equipment, scientific instrumentation, field camp and natural surroundings.

Reproductive endosymbiotic bacteria of Antarctic springtails: on the verge of new discoveries?

open access: yesУкраїнський антарктичний журнал
Endosymbiotic bacteria infect a vast number of invertebrate representatives from diverse taxa. This study reviews the results of identifying endosymbiotic bacteria (specifically the genera Wolbachia, Cardinium, Rickettsia, Arsenophonus and Spiroplasma ...

Characterization of Bacterial, Archaeal and Eukaryote Symbionts from Antarctic Sponges Reveals a High Diversity at a Three-Domain Level and a Particular Signature for This Ecosystem.

open access: yesPLoS ONE, 2015
Sponge-associated microbial communities include members from the three domains of life. In the case of bacteria, they are diverse, host specific and different from the surrounding seawater.

Trematocine, a Novel Antimicrobial Peptide from the Antarctic Fish Trematomus bernacchii: Identification and Biological Activity

open access: yesAntibiotics, 2020
Antimicrobial peptides (AMPs) are short peptides active against a wide range of pathogens and, therefore, they are considered a useful alternative to conventional antibiotics.

Diversity of Cultivable Microbes From Soil of the Fildes Peninsula, Antarctica, and Their Potential Application

open access: yesFrontiers in Microbiology, 2020
To explore the diversity and application potential of Antarctic microorganisms, 1208 strains bacteria and fungi were isolated from 5 samples collected from the Fildes Peninsula during China’s 27th and 31st Antarctic expeditions.

Microbial community composition of transiently wetted Antarctic Dry Valley soils [PDF]

open access: yes, 2015
During the summer months, wet (hyporheic) soils associated with ephemeral streams and lake edges in the Antarctic Dry Valleys (DVs) become hotspots of biological activity and are hypothesized to be an important source of carbon and nitrogen for arid DV ...

Antarctic marine biodiversity and deep-sea hydrothermal vents.

open access: yesPLoS Biology, 2012
The diversity of many marine benthic groups is unlike that of most other taxa. Rather than declining from the tropics to the poles, much of the benthos shows high diversity in the Southern Ocean. Moreover, many species are unique to the Antarctic region.

Toll-Like Receptor Evolution: Does Temperature Matter?

open access: yesFrontiers in Immunology, 2022
Toll-like receptors (TLRs) recognize conserved pathogen-associated molecular patterns (PAMPs) and are an ancient and well-conserved group of pattern recognition receptors (PRRs).
