miRò is a web-based knowledge base that provides users with miRNA–phenotype associations in humans. It integrates data from various online sources, such as databases of miRNAs, ontologies, diseases and targets, into a unified database equipped with an intuitive and flexible query interface and data mining facilities. The main goal of miRò is the(More)
The bacterial community inhabiting the water column at Terra Nova Bay (Ross Sea, Antarctica) was examined by the fluorescent in situ hybridization (FISH) technique and the genotypic and phenotypic characterization of 606 bacterial isolates. Overall, the FISH analysis revealed a bacterioplankton composition that was typical of Antarctic marine environments(More)
Microorganisms from Antarctica have evolved particular strategies to cope with cold. Moreover, they have been recently reported as producers of antimicrobial compounds, which inhibit the growth of other bacteria. In this work we characterized from different viewpoints the Gillisia sp. CAL575 strain, a psychrotrophic bacterium that produces microbial(More)
This review covers available information concerning the bacterial communities inhabiting coastal areas of Terra Nova Bay (Antarctica). Research was mainly focused on seawater, sediment, and benthic filter feeders. Coping with adverse environmental conditions, Antarctic bacteria have evolved peculiar strategies to survive in this harsh environment. In(More)
Culturable psychrotolerant bacteria were isolated from the top snow on the high Antarctic Plateau surrounding the research station Concordia. A total of 80 isolates were recovered, by enrichment cultures, from two different isolation sites (a distant pristine site [75° S 123° E] and a site near the secondary runway of Concordia). All isolates were(More)
We report here the draft genome sequence of the Flavobacterium sp. TAB 87 strain, isolated from Antarctic seawater during a summer campaign near the French Antarctic station Dumont d'Urville (60°40'S, 40°01'E). It will allow for comparative genomics and the fulfillment of both fundamental and application-oriented investigations. It allowed the recognition(More)
Bacteria belonging to the Pseudoalteromonas genus have important ecological implications in marine environments, playing a role in the control of microbial community as producers of bioactive molecules endowed with antifouling activity and able to antagonize larvae, fungi and bacteria, including important human pathogens. For these reasons, representatives(More)
Byers Peninsula (Livingston Island, Antarctica), the largest seasonally ice-free region of the Maritime Antarctica, holds a large number of lakes, ponds, and streams. The prokaryotic structure and bacterial diversity in sediment samples collected during the 2008–2009 austral summer from five inland lakes, two coastal lakes, and an estuarine site were(More)
The cryosphere is an integral part of the global climate system and one of the major habitable ecosystems of Earth's biosphere. These permanently frozen environments harbor diverse, viable and metabolically active microbial populations that represent almost all the major phylogenetic groups. In this study, we investigated the microbial diversity in the(More)
High concentrations of heavy metals have been previously detected in Antarctic sponge tissues, but their effect on the associated bacterial assemblages has been never investigated. Metal tolerance is often linked to antibiotic resistance and can also affect biochemical activities within microbial populations. In the present work, the response to heavy(More)
