Journal ArticleDOI
Long-term habituation to a danger stimulus in the crab Chasmagnathus granulatus.
TL;DR: A shadow moving overhead acts as a danger stimulus and elicits an escape response in the crab Chasmagnathus granulatus, that habituates after 15 stimulus presentations at 3-min intervals and the habituated response persisted after 24 hr in every case.
Journal ArticleDOI
Bioprospection of marine microorganisms: biotechnological applications and methods
TL;DR: The different partially overlapping biotechnological fields that make use of microorganisms are explored and the different marine habitats that are particularly attractive for bioprospection are described.
Journal ArticleDOI
Alkane Biodegradation Genes from Chronically Polluted Subantarctic Coastal Sediments and Their Shifts in Response to Oil Exposure
Lilian M. Guibert,Claudia L. Loviso,Magalí S. Marcos,M.G. Commendatore,Hebe M. Dionisi,Mariana Lozada +5 more
TL;DR: The distribution of alkB sequences among samples of different sites and years, and selection after experimental oil exposure allowed us to identify ecologically relevant alkB genes in Subantarctic sediments, which could be used as biomarkers for alkane biodegradation in this environment.
Journal ArticleDOI
Novel aromatic ring-hydroxylating dioxygenase genes from coastal marine sediments of Patagonia.
Mariana Lozada,Juan Pablo Riva Mercadal,Leandro D Guerrero,Walter Dario Di Marzio,Marcela Alejandra Ferrero,Hebe M. Dionisi +5 more
TL;DR: These results show the presence of hitherto unidentified ARHD genes in this sub-Antarctic marine environment exposed to anthropogenic contamination, and can be used to study the geographical distribution and ecological significance of bacterial populations carrying these genes, and to design molecular assays to monitor the progress and effectiveness of remediation technologies.
Journal ArticleDOI
Isolation and characterization of biosurfactant-producing Alcanivorax strains: hydrocarbon accession strategies and alkane hydroxylase gene analysis.
Nelda Lila Olivera,Marina L. Nievas,Mariana Lozada,Guillermo del Prado,Hebe M. Dionisi,Faustino Siñeriz +5 more
TL;DR: Biosurfactant production was only detectable at late growth and stationary phases, suggesting that it is not involved in initiating oil degradation and that direct interfacial adhesion is the main hydrocarbon accession mode of PA2.
