 Obiettivo del progetto (Objective)

'Methane, a key greenhouse gas, is cycled by microorganisms via two pathways, aerobically and anaerobically. Research on the marine methane cycle has mainly concentrated on anaerobic processes. Recent biomarker work has provided compelling evidence that aerobic methane oxidation (AMO) can play a more significant role in cycling methane emitted from sediments than previously considered. AMO, however, is not well studied requiring novel proxies that can be applied to the sedimentary record. A group of complex lipids biosynthesised by aerobic methanotrophs known as aminobacteriohopanepolyols represent an ideal target for developing such poxies. Recently BHPs have been identified in a wide range of modern and recent environments including a continuous record from the Congo deep sea fan spanning the last 1.2 million years. In this integrated study, the regulation and expression of BHP will be investigated and calibrated against environmental variables including temperature, pH, salinity and, most importantly, methane concentrations. The work program has three complementary strands. (1) Pure culture and sedimentary microcosm experiments providing an approximation to natural conditions. (2) Calibration of BHP signatures in natural marine settings (e.g. cold seeps, mud volcanoes, pockmarks) against measured methane gradients. (3) Application of this novel approach to the marine sedimentary record to approximate methane fluxes in the past, explore the age and bathymetric limits of this novel molecular proxy, and identify and potentially 14C date palaeo-pockmarks structures. Crucial to the success is also the refinement of the analytical protocols to improve both accuracy and sensitivity, using a more sensitive analytical instrument (triple-quadrupole mass spectrometer).'
