Antarctic Soils Select Copiotroph-Dominated Bacteria

Microorganisms
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

Український 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 ...

Polyphase Taxonomy of Antarctic Bacteria [PDF]

Mikrobiolohichnyi 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.

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

Polymers (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.

Lipases from psychrotropic antarctic bacteria [PDF]

FEMS 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 ...

Kineochelins-A New Group of Siderophores From an Antarctic Bacterium. [PDF]

Microb Biotechnol
Genome‐guided analysis of an Antarctic Actinokineospora strain led to the discovery of kineochelins, a new group of siderophores involved in iron sequestration and microbial competition. Kineochelin production inhibits co‐occurring bacteria and clinically relevant yeasts, highlighting Antarctic microorganisms as promising sources of bioactive natural ...

Structure and application of antifreeze proteins from Antarctic bacteria. [PDF]

Microb Cell Fact, 2017
Antifreeze proteins (AFPs) production is a survival strategy of psychrophiles in ice. These proteins have potential in frozen food industry avoiding the damage in the structure of animal or vegetal foods. Moreover, there is not much information regarding the interaction of Antarctic bacterial AFPs with ice, and new determinations are needed to ...

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

Anais 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 ...
