Background Metagenomics is emerging as a powerful method to study the function and physiology of unexplored microbial biosphere, causing us re-evaluate basic precepts ecology evolution. Most marine metagenomic analyses have been nearly exclusively devoted photic waters. Methodology/Principal Findings We constructed fosmid library from 3,000 m-deep Mediterranean plankton, which much warmer (∼14°C) than waters similar depth in open oceans (∼2°C). analyzed both by phylogenetic screening based...
Microcosm experiments simulating an oil spill event were performed to evaluate the response of natural microbial community structure Messina harbour seawater following accidental load petroleum.An experimental microcosm, supplemented with nutrients and crude oil, was monitored above 15 days in comparison unpolluted ones (control microcosms). Bacterial cells counted a Live/Dead BacLight viability kit; leucine aminopeptidase, beta-glucosidase, alkaline phosphatase, lipase esterase enzymes...
Abstract Deep-sea hypersaline anoxic lakes (DHALs) of the Eastern Mediterranean represent some most hostile environments on our planet. We investigated microbial life in recently discovered Lake Medee , largest DHAL found to-date. has two unique features: a complex geobiochemical stratification and an absence chemolithoautotrophic Epsilonproteobacteria, which usually play primary role dark bicarbonate assimilation DHALs interfaces. Presumably because these features, is less productive...
The marine pelagic zone situated > 200 m below the sea level (bls) is largest subsystem, comprising more than two-thirds of oceanic volume. At same time, it one least explored ecosystems on Earth. Few large-scale environmental genomics studies have been undertaken to examine phylogenetic diversity and functional gene repertoire planktonic microbes present in mesopelagic bathypelagic environments. Here, we description deep-sea microbial community thriving at 4900 depth Matapan-Vavilov Deep...
Abstract Planktonic communities hold a relevant role within the EU Marine Strategy Framework Directive (MSFD). In view of reaching Good Environmental Status marine ecosystems, this phyto- and zooplanktonic have received great attention, while Prokaryotes (Bacteria, Archaea, Cyanobacteria) been neglected. Indeed, relevance microbes (particularly faecal pollution indicators) as water quality indicators, that microorganisms play biogeochemical fluxes in whole ecosystem functioning, are all...
Abstract In the framework of VECTOR DIVCOST Project, a 2‐year investigation was started in 2006, with aim testing sensibility microbial parameters to environmental changes and assessing whether they can provide information about functional carbon cycle. The performed surface waters two small brackish ponds (Ganzirri Faro), located Cape Peloro transitional area (Sicily, Italy). seasonal both compartment [bacterioplankton, vibrios, exoenzymatic hydrolysis proteins polysaccharides, bacterial...
Dissolved and particulate organic carbon, bacterial biomass, microbial enzymatic activities (EEA: leucine aminopeptidase, β‐glucosidase, alkaline phosphatase), production, respiration rates, growth efficiency were determined in 10 stations of the Ionian Sea (winter 1998–1999) with aim characterizing recycling biogenic carbon phosphorus different water masses, previously identified on basis their hydrographical properties. All decreased markedly depth, a sharp increase benthic boundary layer,...
Three microbial extracellular enzymes, leucine aminopeptidase (LAP), β-glucosidase (β-glu) and alkaline phosphatase (AP), were studied in six small Mediterranean littoral ponds, to evaluate the diversity of activities relative prevailing environmental conditions. The marked diversification trophic states, ranging from oligotrophy eutrophy, ponds was reflected a range enzyme patterns at different spatial temporal scales. There higher levels greater variability activity oldest most ‘confined’...
A synthesis of field data carried out in the Mediterranean Sea are presented, aimed at contributing to knowledge three prokaryotic-mediated processes and their implications on Carbon cycle. The distribution exoenzymatic activities, secondary production respiration rates was studied together with prokaryotic abundances. Particular attention paid meso- bathypelagic layers which play an important role carbon study is noteworthy because its large spatial scale spanning entire over 4 years. In...
The Ionian Sea represents a suitable basin for studying the biogeochemical processes mediated by microbial activities. Because of its characteristics as crossing region between western and eastern Mediterranean Sea, it is one sites most affected changes in water mass composition dynamics, caused Eastern Transient (EMT). To date, relatively few data exist on activities pelagic areas Sea. From 1998 to 2004, during different research cruises, prokaryotic parameters (abundance, extracellular...
Abstract This paper presents a winter carbon budget for the northern Adriatic Sea, obtained through direct measurements during two multidisciplinary cruises and literature data. A box model approach was adopted to integrate estimates of stocks fluxes species over total area. The oligotrophy at basin scale start primary productivity well before onset spring stratification were observed. In winter, system underwent complete reset, as mixing water masses erased any signal previous hypoxia or...
Covering two-thirds of our planet, the global deep ocean plays a central role in supporting life on Earth. Among other processes, this biggest ecosystem buffers rise atmospheric CO2. Despite carbon sequestration has been known for long time, microbial activity meso- and bathypelagic realm via 'assimilation bicarbonate dark' (ABD) only recently described more details. Based recent findings, process seems primarily result chemosynthetic anaplerotic reactions driven by different groups deep-sea...
