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:Although the key role of long-distance trade in the transformation of cuisines worldwide has been well-documented since at least the Roman era, the prehistory of the Eurasian food trade is less visible. In order to shed light on the transformation of Eastern Mediterranean cuisines during the Bronze and Early Iron Age, we analyzed microremains and proteins preserved in the dental calculus of individuals who lived during the 2nd millennium BCE in the Southern Levant. Our results provide clear evidence for the consumption of expected staple foods, such as cereals (Triticeae), sesame (Sesamum) and dates (Phoenix). We additionally report evidence for the consumption of soybean (Glycine), probable banana (Musa), and turmeric (Curcuma), which pushes back the earliest known availability of these foods in the Mediterranean by centuries (turmeric) or even millennia (soybean). We find that, from the early 2nd millennium onwards, at least some people in the Eastern Mediterranean had access to food from distant locations, including South Asia, and such trade goods likely reached the Eastern Mediterranean in the form of oils, dried fruits, and spices. These novel insights force us to rethink the complexity and intensity of Indo-Mediterranean trade during the Bronze Age and also the degree of globalization in early Eastern Mediterranean cuisine.

Project description:The Baltic Sea is one of the largest brackish water bodies in the world. Redoxclines that form between oxic and anoxic layers in the deepest sub-basins are a semi-permanent character of the pelagic Baltic Sea. The microbially mediated nitrogen removal processes in these redoxclines have been recognized as important ecosystem service that removes large proportion of the nitrogen load originating from the drainage basin. However, nitrification, which links mineralization of organic nitrogen and nitrogen removal processes, has remained poorly understood. To gain better understanding of the nitrogen cycling in the Baltic Sea, we analyzed the assemblage of ammonia oxidizing bacteria and archaea in the central Baltic Sea using functional gene microarrays and measured the biogeochemical properties along with potential nitrification rates. Overall, the ammonia oxidizer communities in the Baltic Sea redoxcline were very evenly distributed. However, the communities were clearly different between the eastern and western Gotland Basin and the correlations between different components of the ammonia oxidizer assemblages and environmental variables suggest ecological basis for the community composition. The more even community ammonia oxidizer composition in the eastern Gotland Basin may be related to the constantly oscillating redoxcline that does not allow domination of single archetype. The oscillating redoxcline also creates long depth range of optimal nitrification conditions. The rate measurements suggest that nitrification in the central Baltic Sea is able to produce all nitrate required by denitrification occurring below the nitrification zone.
