Antarctic Soils Select Copiotroph-Dominated Bacteria

open access: yesMicroorganisms
The life strategies of bacterial communities determine their structure and function and are an important driver of biogeochemical cycling. However, the variations in these strategies under different soil resource conditions remain largely unknown.

Biocontrol potential of Antarctic endophytic bacteria

open access: yesУкраїнський антарктичний журнал
Antarctic endophytes, adapted to harsh environmental conditions, possess unique metabolic capabilities that can influence plant-microbe interactions. In this study, we investigated the impact of 15 plant growth-promoting bacterial strains isolated from ...

Biodeterioration of Untreated Polypropylene Microplastic Particles by Antarctic Bacteria. [PDF]

open access: yesPolymers (Basel), 2020
Microplastic pollution is globally recognised as a serious environmental threat due to its ubiquitous presence related primarily to improper dumping of plastic wastes. While most studies have focused on microplastic contamination in the marine ecosystem, microplastic pollution in the soil environment is generally little understood and often overlooked.

Polyphase Taxonomy of Antarctic Bacteria [PDF]

open access: yesMikrobiolohichnyi Zhurnal, 2021
The phylogenetic structure of bacteria is not always consistent with the traditional classification scheme based on the phenotypic properties of bacteria. That is one of the problems of modern bacterial taxonomy. In addition, traditional methods to identify bacteria using phenotypic properties have a number of disadvantages.

Lipases from psychrotropic antarctic bacteria [PDF]

open access: yesFEMS Microbiology Letters, 1990
Properties of lipases excreted by 4 psychrotropic Moraxella strains from antarctic sea water have investigated. Despite an optimal cell generation time at 25°C, maximal lipase excretion essentially occurs at low temperatures. These enzymes are characterized by a shift of the apparent optimal activity towards low temperatures, by a reduction of the ...

VIABILITY OF COLIFORM BACTERIA IN ANTARCTIC SOIL [PDF]

open access: yesJournal of Bacteriology, 1963
Boyd, William L. (Ohio State University, Columbus) and Josephine W. Boyd . Viability of coliform bacteria in antarctic soil. J. Bacteriol. 85: 1121–1123. 1963.—The distribution of coliform bacteria in soils of Ross Island and the nearby mainland was studied.

Enzymatic Activity of Psychrotolerant Antarctic Bacteria [PDF]

open access: yesMikrobiolohichnyi Zhurnal, 2021
The Antarctic region has significant potential to study the biodiversity of microorganisms and to search for bacterial producers of glycolytic and proteolytic enzymes with new properties. The aim was to study the extracellular glycosidase and proteolytic activity of four bacteria strains isolated from black lichens of the cliffs of Galindez Island in ...

Aerobiology in High Latitudes: Evidence of Bacteria Acting as Tracer of Warm Air Mass Advection reaching Northern Antarctic Peninsula [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2023
Despite the extent use of geochemical tracers to track warm air mass origin reaching the Antarctic continent, we present here evidences that microorganisms being transported by the atmosphere and deposited in fresh snow layers of Antarctic ice sheets do ...

Insight Into Ecology, Metabolic Potential, and the Taxonomic Composition of Bacterial Communities in the Periodic Water Pond on King George Island (Antarctica)

open access: yesFrontiers in Microbiology, 2021
Polar regions contain a wide variety of lentic ecosystems. These include periodic ponds that have a significant impact on carbon and nitrogen cycling in polar environments.

Gastrointestinal Bacteria of Certain Antarctic Birds and Mammals [PDF]

open access: yesApplied Microbiology, 1970
An investigation was carried out of the aerobic gram-negative intestinal flora of 158 penguins, 30 skuas, and 66 seals from the Antarctic and sub-Antarctic zones and Phillip Island. Among penguins and seals, 17% and 11%, respectively, were devoid of aerobic enteric organisms, but microscopic examination showed the presence of other
