Unravelling the molecular basis of metabolic interactions in synthetic consortia dedicated for bio-H2 production

Romanian Moldavia is the focus of a study, initiated in 2005, on Neolithic-Eneolithic (6000–3500 BCE) settlement dynamics and salt exploitation. The underlying hypothesis that exploitation salt, along with copper gold, contributed to emergence developed Eneolithic societies from beginning 5th millennium BC. By approaching this process through its geographical dimension, 6th BC, one can measure simultaneity certain facts, be they social (the affirmation elites), territorial appearance controlling sites), or technical (first metallurgy, intensification exploitation).The sub-Carpathian region eastern Romania particularly interesting, as density springs much higher than elsewhere, dating Early Neolithic (Criș) subsequently develops into an cultural centre (Precucuteni Cucuteni) unequalled wealth importance.After decade research nature use resources, together creation archaeological database covering period 6000 BCE 3500 BCE, we now undertake preliminary assessment strategies implemented by these Carpathian region. Archaeological approaches are enhanced powerful tools such GIS application spatial analysis methods thus enabling us model patterns dynamics.Following analyses, several results emerge. A coherent observed for Neolithic: sites, which often grouped currently inter-visible, located valley zones modest terraces close minor water courses. With Linearbandkeramik (LBK) culture, situation evolves: more dispersed, settlements established open landscape.In first half millennium, witness radical change preferred topographical contexts: high- mid-altitude favoured, trend reflected establishment promontories provide commanding views over wider area. Following marked diversification forms land second 4th characterised densification population centres strengthening control.Analyses accessibility allow observations further developed. Firstly, note significant increase sites spanning millennium. It precisely during two phases appears increase. Secondly, numbers important fortified prestige goods (copper axes) occurring illustrates polarising role resources.
