Project description:Physiological and gene expression studies of deep-sea bacteria under pressure conditions similar to those experienced in their natural habitat are critical to understand growth kinetics and metabolic adaptations to in situ conditions. The Epslilonproteobacterium, Nautilia sp. strain PV1, was isolated from hydrothermal fluids released from an active deep-sea hydrothermal vent at 9°N on the East Pacific Rise. Using a high pressure/high temperature continuous culture system we established that strain PV-1 has the shortest generation time of all known piezophilic microorganisms and we investigated its protein expression pattern in response to different hydrostatic pressures. Proteomic analyses of strain PV-1 grown at 200 Bars and 5 Bars showed that pressure adaptation is not restricted only to stress response or homeoviscous adaptation, but that it is more diversified and protein specific, with a fine and variegated regulation of enzymes involved even in the same metabolic pathway. As previously reported, proteins synthesis, motility, transport and energy metabolism are all affected by pressure, although to different extents. In strain PV-1, low pressure condition seems to activate the synthesis of phage-related proteins and an overexpression of enzymes involved in central carbon metabolism.

Project description:The goal of this study was to identify the key functions of the six main symbionts that are hosted in gills of the marine bivalve, Idas modiolaeformis, which lives at deep-sea hydrocarbon seeps and wood falls in the Eastern Atlantic Ocean and the Mediterranean Sea. These symbionts include the main autotrophic methane- and sulfur-oxidizing lineages (Methyloprofundus, Thioglobus, Thiodubillierella), as well as a Methylophagaceae methylotrophic autotroph, a flavobacterial degrader of complex polysaccharides Urechidicola and a Nitrincolaceae heterotroph that specializes in degradation of nitrogen-rich compounds such as peptides and nucleosides. Four I. modiolaeformis individuals were preserved in RNAlater following retrieval from a brine pool habitat in the Eastern Mediterranean at 1,150 m water depth (32° 13.4' N 34° 10.7' E), using a remotely-operated vehicle. RNAlater was discarded after 24 hours, and the specimens were kept at -80°C until DNA/RNA/protein co-extraction using the AllPrep DNA/RNA/Protein Mini Kit (Cat. No. 80004, Qiagen).

Project description:We compared genetic profiles of planktonic stage to biofilm stage of deep sea bacterium Pseudoalteromonas sp. SM9913 and revealed genetic features during switch from planktonic to pellicle stage in Pseudoalteromonas sp. SM9913. mRNA profiles of Pseudoalteromonas sp. SM9913 planktonic cells, initial pellicle cells and mature pellicle cells were generated by Illumina Hiseq2000.

Project description:Despite the fact that deep sea mining is becoming more popular nowadays in terms of obtaining metals ores for daily life purposes, its potential impact to the deep sea habitat, which is originally stable and converse, stills remains uncertain. In order to estimate and regulate the imapct of deep sea mining activities, an in-situ exposure experiment is performed to observe the change in proteomics expression of the deep-sea scvangers, Abyssorchomene distinctus, to copper exposure. This project aims to suggest a potenial protein bio-marker in Abyssorchomene distinctus to assess the impact of mining activities towards deep sea organisms and also discuss the potential application of other deep sea in-situ exposure experiment in the future.

Project description:The present study describes the isolation of a Thermococcus sp. strain 175 from the world‘s deepest hydrothermal vent sites known thus far – The Mid-Cayman Rise.consisting of two hydrothermal venting systems Bee Bee (or Piccard), at 4950m depth and Von Damm (or Walsh) at 2300m The strain is capable of growth over 0.1MPa (atm. Pressure) to 120MPa, the widest known range of pressure dependent growth. The study further explores piezophilic adaptation using comparative genomic tools. Insights into the transcriptome of this strain providers the first look into the transcriptional machinery of peizophilic Thermococci.

Project description:As part of our investigations on the chemical diversity of organisms from unexplored marine habitats of Mexico, a series of 29 fungal strains isolated from deep-sea sediments (more than 600 m deep) from the Gulf of Mexico were investigated. The antimicrobial potential of their organic extracts from solid cultures grown under the OSMAC approach was assessed against a panel of ESKAPE bacteria and the yeast C. albicans. Chemical studies on the active scaled-up cultures and some small-scale cultures led to the isolation of benzochromenones from Alternaria sp. CIGOM4, benzodiazepines from P. echinulatum CONTIG4, a cytochalsin from Biatriospora sp. CIGOM2, and an imidazopyridoindole from Penicillium sp. CIGOM10. Molecular network analysis by GNPS combined with manual dereplication showed the enormous potential of these fungi to produce bioactive compounds.
