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 [PDF]

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 ...

Biological Activities of Ethanolic Extracts from Deep-Sea Antarctic Marine Sponges [PDF]

Marine Drugs, 2013
We report on the screening of ethanolic extracts from 33 deep-sea Antarctic marine sponges for different biological activities. We monitored hemolysis, inhibition of acetylcholinesterase, cytotoxicity towards normal and transformed cells and growth ...

Diversity and Physiological Characteristics of Antarctic Lichens-Associated Bacteria [PDF]

Microorganisms, 2021
The diversity of lichen-associated bacteria from lichen taxa Cetraria, Cladonia, Megaspora, Pseudephebe, Psoroma, and Sphaerophorus was investigated by sequencing of 16S rRNA gene amplicons.

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 ...

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

, 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.

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 ...
