Aromatic hydrocarbon degradation genes from chronically polluted Subantarctic marine sediments
(Wiley Blackwell Publishing, Inc, 2009-11)
Aim: The goal of this study was to identify functional targets to detect polycyclic aromatic hydrocarbon (PAH)-degrading bacterial populations in cold marine ecosystems. Methods and Results: We designed a degenerate primer ...
Abundance, dynamics, and biogeographic distribution of seven Polycyclic aromatic hydrocarbon dioxygenase gene variants in coastal sediments of Patagonia
(American Society for Microbiology, 2012-02)
Novel polycyclic aromatic hydrocarbon dioxygenase gene variants were present in abundances similar to or higher than those of phnA1 from Cycloclasticus spp. at a chronically polluted subantarctic coastal marine environment ...
The skin of Commerson's dolphins (Cephalorhynchus commersonii) as a biomonitor of mercury and selenium in Subantarctic waters
(Elsevier, 2015-07)
The skin of bycaught Commerson’s dolphins was tested for mercury (Hg) and selenium (Se) biomonitoring in Subantarctic environments. The correlation of levels detected in the skin with those found in internal tissues – lung, ...
Aromatic hydrocarbon degradation genes from chronically polluted subantarctic marine sediments
(Wiley, 2011)
With the goal of identifying functional biomarkers associated with polycyclic aromatic hydrocarbon (PAH) biodegradation in chronically-polluted Subantarctic marine sediments, we amplified from environmental metagenomic ...
Diversity of protease-producing marine bacteria from sub-antarctic environments
(Wiley VCH Verlag, 2011-12)
From seawater and the intestines of benthonic organisms collected from the Beagle Channel, Argentina, 230 marine bacteria were isolated. Cultivable bacteria were characterized and classified as psychrotolerant, whereas few ...
Metagenomics reveals the high polycyclic aromatic hydrocarbon-degradation potential of abundant uncultured bacteria from chronically polluted subantarctic and temperate coastal marine environments
(Wiley Blackwell Publishing, Inc, 2015-06-16)
Aims: To investigate the potential to degrade polycyclic aromatic hydrocarbons (PAHs) of yet-to-be-cultured bacterial populations from chronically polluted intertidal sediments. Methods and Results: A gene variant encoding ...
Predominance and high diversity of genes associated to denitrification in metagenomes of subantarctic coastal sediments exposed to urban pollution
(Public Library of Science, 2018-11)
The aim of this work was to characterize the microbial nitrogen cycling potential in sediments from Ushuaia Bay, a subantarctic environment that has suffered a recent explosive demographic growth. Subtidal sediment samples ...
Characterization of inducible cold-active β-glucosidases from the psychrotolerant bacterium Shewanella sp. G5 isolated from a sub-Antarctic ecosystem
(Elsevier Science Inc, 2009-12)
The psychrotolerant bacterium Shewanella sp. G5 was used to study differential protein expression on glucose and cellobiose as carbon sources in cold-adapted conditions. This strain was able to growth at 4 °C, but reached ...
Cryptic speciation in gentoo penguins is driven by geographic isolation and regional marine conditions: Unforeseen vulnerabilities to global change
(Wiley Blackwell Publishing, Inc, 2020-05)
Aim: The conservation of biodiversity is hampered by data deficiencies, with many new species and subspecies awaiting description or reclassification. Population genomics and ecological niche modelling offer complementary ...
Nitrate reduction activity determined with a continuous flow-through system in sediments from a subantarctic coastal environmentActividad nitrato reductora determinada con un sistema de flujo continuo en sedimentos de un ambiente costero subantártico
(Instituto de Oceanología, 2012-08)
Sedimentation and accumulation of autochthonous and allochthonous organic detritus in marine sediments stimulate microbial activity, consume dissolved oxygen and decrease redox potential. In anaerobic conditions, other ...
