The biosphere of planet Earth is delineated by physico-chemical conditions that are too harsh for, or inconsistent with, life processes and maintenance the structure function biomolecules. To define window on (and perhaps gain insights into limits could tolerate elsewhere), hence understand some most unusual biological activities operate at such extremes, it necessary to causes cellular basis systems failure beyond these windows. Because water plays a central role in biomolecules...
Summary Hydrocarbon‐contaminated superficial sediments collected from the Harbor of Milazzo (Tirrenean Sea, northern Sicily), a zone strongly affected by anthropogenic activities, were examined for in situ biodegradative capacities. A culture‐independent molecular phylogenetic approach was used to study influence hydrocarbon and nutrient addition on activity diversity indigenous microbiota during microcosm evaluation. The autochthonous microbial community non‐polluted represented eubacterial...
Summary There is little information on how different strategies for the bioremediation of marine oil spills influence key indigenous hydrocarbon‐degrading bacteria (hydrocarbonoclastic bacteria, HCB), and hence their remediation efficacy. Therefore, we have used quantitative polymerase chain reaction to analyse changes in concentrations HCB response intervention applied experimental microcosms. Biostimulation with nutrients (N P) produced no measurable increase either biodegradation or...
Ubiquitous bacteria from the genus Oleispira drive oil degradation in largest environment on Earth, cold and deep sea. Here we report genome sequence of antarctica show that compared with Alcanivorax borkumensis—the paradigm mesophilic hydrocarbonoclastic bacteria—O. has a larger witnessed massive gene-transfer events. We identify an array alkane monooxygenases, osmoprotectants, siderophores micronutrient-scavenging pathways. also at low temperatures, main protein-folding machine Cpn60...
Abstract Two of the largest crude oil-polluted areas in world are semi-enclosed Mediterranean and Red Seas, but effect chronic pollution remains incompletely understood on a large scale. We compared influence environmental geographical constraints anthropogenic forces (hydrocarbon input) bacterial communities eight geographically separated sites along coastlines Seas. The differences community compositions their biodegradation potential were primarily associated (P < 0.05) with both...
The purpose of present study was the simulation an oil spill accompanied by burial significant amount petroleum hydrocarbons (PHs) in coastal sediments. Approximately 1,000 kg sediments collected Messina harbor were spiked with Bunker C furnace fuel (6,500 ppm). rapid consumption oxygen aerobic heterotrophs created highly reduced conditions subsequent recession biodegradation rates. As follows, after three months ageing, anaerobic did not exhibit any levels and more than 80% added remained...
Crude oil is one of the most important natural assets for humankind, yet it a major environmental pollutant, notably in marine environments. One largest crude polluted areas word semi‐enclosed Mediterranean Sea, which metabolic potential indigenous microbial populations towards large‐scale chronic pollution to be defined, particularly anaerobic and micro‐aerophilic sites. Here, we provide an insight into metabolism sediments from three chronically sites along coastline Italy: Priolo...
The effects of the co-location energy production from a photovoltaic (PV) plant and aromatic crops (thyme, oregano, Greek mountain tea) in hot dry environment have been investigated Enel Green Power PV located Kourtesi (Greece). study was aimed at evaluating influence on microclimate, soil temperature water potential, crops’ growth testing area (the corridors between two modules rows) compared to full sunlight control area. net radiation wind speed recorded showed 44% 38% reduction...
Summary The distribution of bacterial communities terminal restriction fragment length polymorphism (T‐RFLP) fingerprint patterns was evaluated at three proximal hydrocarbon‐contaminated sites located within the harbour Messina. In order to analyse short‐term variability individual (T‐RF) patterns, water samples were collected on occasions 3 months (T 0 , T 90 and 91 ). Four sample sizes, from 50 1000 ml for each sample, analysed separately (36 total samples) evaluate relationship between...
In this study, we evaluated the removal efficiency of fuel hydrocarbons from a jet contaminated area using bioaugmentation treatment in biopile.The hydrocarbon analysis sample revealed total mainly constituted by benzene, toluene, ethylbenzene, xylenes (BTEX) and heavy aliphatic hydrocarbons. Enrichments soil were performed with BTEX, pristane JP-5, respectively, selected hydrocarbon-degrading strains, namely Acinetobacter sp., Pseudomonas sp. Rhodococcus Three hundred litres culture...
Summary Dark ocean microbial communities are actively involved in chemoautotrophic and anaplerotic fixation of bicarbonate. Thus, aphotic pelagic realm the might represent a significant sink CO 2 source primary production. However, estimated metabolic activities dark fraught with uncertainties. Typically, deep‐sea samples recovered to sea surface for downstream processing on deck. Shifts ambient settings, associated such treatments, can likely change activity community structure adapted...
The development of monitoring strategies for the early warning seawater pollution, with particular reference to faecal and hydrocarbon contamination, has been specific goal research carried out within Cluster 10-SAM (Advanced Systems Coastal Marine Monitoring) Project, funded by Italian Ministry University Scientific Research. Advanced analytical approaches have designed applied detect bacterial species that selected as potential indicators pollution in samples. We report results obtained...
Oil spill microcosms experiments were carried out to evaluate the effect of bioemulsificant exopolysaccharide (EPS2003) on quick stimulation hydrocarbonoclastic bacteria. Early hours oil spill, stimulated using an experimental seawater microcosm, supplemented with crude and EPS2003 (SW+OIL+EPS2003); this system was monitored for 2 days compared control microcosm (only oil-polluted seawater, SW+OIL). Determination bacterial abundance, heterotrophic cultivable hydrocarbon-degrading bacteria...
The aims of this study were: (i) the characterization structure indigenous microbial community associated with sediments under study; (ii) isolation and consortia able to degrade aged hydrocarbons contaminating sediments, (iii) assessment related biodegradation capability selected consortia. Samples surface were collected in Priolo Gargallo harbour (Sicily, Italy). samples analysed for physical, chemical (GC-FID analysis) microbiological characteristics (qualitative (16S rDNA clone library)...
Three bacterial species related to the genus Thalassospira (T. lucentensis, T. xianhensis and profundimaris), isolated from polluted sediment seawater samples collected Priolo Bay (eastern coast of Sicily, Ionian Sea), were analyzed for their biotechnological potential. For this purpose, presence specific catabolic genes associated aliphatic aromatic hydrocarbon metabolism, production biosurfactants emulsification activity, capability degrade oil-derived linear, branched, cyclic alkanes,...
Five psychrotolerant Alcanivorax spp. strains were isolated from Antarctic coastal waters. Strains screened for molecular and physiological properties analyzed regarding their growth capacity. Partial 16S rDNA, alk-B1, P450 gene sequencing was performed. Biolog EcoPlates the API 20E test used to evaluate metabolic biochemical profiles. Bacterial in sodium acetate determined at 4, 15, 20, 25 °C optimal temperature. Furthermore, ability of each strain grow a hydrocarbon mixture 4 assayed....
