How the bacterial community of a tannery effluent responds to bioaugmentation with the consortium SFC 500-1. Impact of environmental variables
(Elsevier Inc, 2019-10-01)
Bioaugmentation with the consortium SFC 500-1 is a promising alternative to remediate wastewaters, such as tannery effluents. With the aim of assessing the changes produced in response to bioaugmentation, bacterial 16S ...
Influence of Climate on Soil and Wine Bacterial Diversity on a Vineyard in a Non-traditional Wine Region in Argentina
(Frontiers Media, 2021-08-12)
Argentina is the fifth world-wide wine producer, with an area of emerging importance in the Southwest of Buenos Aires Province, where climatic conditions are rather challenging. We studied the variations in soil and wine ...
Fast decolorization of azo dyes in alkaline solutions by a thermostable metal-tolerant bacterial laccase and proposed degradation pathways
(Springer Tokyo, 2020-07)
Biocatalytic decolorization of azo dyes is hampered by their recalcitrance and the characteristics of textile effluents. Alkaline pH and heavy metals present in colored wastewaters generally limit the activity of enzymes ...
High phosphorus content in leachates of the austral beech nothofagus pumilio stimulates bacterioplankton c-consumption
(University of Chicago Press, 2019-09)
In the Northern Patagonian Andes, the austral beech Nothofagus pumilio dominates the upper limit of the temperate forest and is an important source of allochthonous dissolved organic matter (DOM) in mountain lakes. In ...
Observed frequency-independent torque in flagellar bacterial motors optimizes space exploration
(American Physical Society, 2012-12-17)
A surprising feature of many bacterial motors is the apparently conserved form of their torque-frequency relation. Experiments indicate that the torque provided by the bacterial rotary motor is approximately constant over ...
Chitosan and cloxacillin combination improve antibiotic efficacy against different lifestyle of coagulase-negative Staphylococcus isolates from chronic bovine mastitis
(Nature Publishing Group, 2018-12-23)
Bovine mastitis affects the health of dairy cows and the profitability of herds worldwide. Coagulase-negative staphylococci (CNS) are the most frequently isolated pathogens in bovine intramammary infection. Based on the ...
Habitat heterogeneity and connectivity shape microbial communities in South American petlands
(Nature Publishing Group, 2016-05)
Bacteria play critical roles in peatland ecosystems. However, very little is known of how habitat heterogeneity affects the structure of the bacterial communities in these ecosystems. Here, we used amplicon sequencing of ...
Marine bacterial community structure resilience to changes in protist predation under phytoplankton bloom conditions
(Nature Publishing Group, 2016-03)
To test whether protist grazing selectively affects the composition of aquatic bacterial communities, we combined high-throughput sequencing to determine bacterial community composition with analyses of grazing rates, ...
Influence of allochthonous dissolved organic matter on pelagic basal production in a northerly estuary
(Academic Press Ltd - Elsevier Science Ltd, 2018-05)
Phytoplankton and heterotrophic bacteria are key groups at the base of aquatic food webs. In estuaries receiving riverine water with a high content of coloured allochthonous dissolved organic matter (ADOM), phytoplankton ...
Interactions of “de novo” designed peptides with bacterial membranes: Implications in the antimicrobial activity
(Elsevier Science, 2020-11)
Antimicrobial peptides are small molecules that display antimicrobial activity against a wide range of pathogens. In a previous work, by using model membranes we studied P6, a peptide that shows no antimicrobial activity, ...
