Newcastle disease virus in penguins from King George Island on the Antarctic region
(ELSEVIER SCIENCE BV, 2010)
Here we report the isolation of Newcastle disease virus (NDV) from cloacal swabs obtained from penguins in the South Atlantic Antarctic region (62 degrees 08S, 58 degrees 25W). Samples of 100 penguins from King George ...
High Prevalence of Gammaproteobacteria in the Sediments of Admiralty Bay and North Bransfield Basin, Northwestern Antarctic Peninsula
(Frontiers Media Sa, 2017)
Microorganisms dominate most Antarctic marine ecosystems, in terms of biomass and taxonomic diversity, and play crucial role in ecosystem functioning due to their high metabolic plasticity. Admiralty Bay is the largest bay ...
In situ rhizosphere microbiome in antarctic vascular plants, modulated by soil condition
(American Society for Microbiology, 2020-12-10)
Antarctic soils are considered young soils; therefore, the microbiota associated with Antarctic vascular plants play a critical role in their productivity. In this research, we compared the microbiota from three different ...
Activity of Antarctic fungi extracts against phytopathogenic bacteria
(2018-06-01)
This study aims to obtain secondary metabolites extracts from filamentous fungi isolated from soil and marine sediments from Antarctic ecosystems and to assess its potential antibacterial activity on Xanthomonas euvesicatoria ...
Influence of nutrients addition and bioaugmentation on the hydrocarbon biodegradation of a chronically contaminated Antarctic soil
(Wiley Blackwell Publishing, Inc, 2009-04)
Complexity involved in the transport of soils and the restrictive legislation for the area makes on‐site bioremediation the strategy of choice to reduce hydrocarbons contamination in Antarctica. The effect of biostimulation ...
Antarctic yeasts: analysis of their freeze-thaw tolerance and production of antifreeze proteins, fatty acids and ergosterol
(BMC, 2018-07-05)
Background: Microorganisms have evolved a number of mechanisms to thrive in cold environments, including the production of antifreeze proteins, high levels of polyunsaturated fatty acids, and ergosterol. In this work, ...
Characterization of the Gut microbiota of the Antarctic Heart Urchin (Spatangoida) Abatus agassizii
(Frontiers Media, 2020)
Abatus agassizii is an irregular sea urchin species that inhabits shallow waters of South Georgia and South Shetlands Islands. As a deposit-feeder, A. agassizii nutrition relies on the ingestion of the surrounding sediment ...
Elucidating viral communities during a phytoplankton bloom on the west Antarctic Peninsula
(Frontiers Media, 2019)
In Antarctic coastal waters where nutrient limitations are low, viruses are expected to play a major role in the regulation of bloom events. Despite this, research in viral identification and dynamics is scarce, with limited ...
Draft genomic DNA sequence of the multi-resistant sphingomonas sp. strain AntH11 isolated from an Antarctic hypolith
(Wiley Blackwell Publishing, Inc, 2015-04)
Hypoliths are microbial communities that live underneath translucent rocks in desert ecosystems and represent a key refuge niche in the Antarctic Dry Valleys. These cryptic microbial assemblages are crucial as they mediate ...
