Abstract

This project aims to understand, through the magnetic and mineralogical properties of sediments, the various environmental conditions of benthic micro-ecosystems based on the presence of magnetotatic bacteria. With more detail to the different materials, this project aims to understand if there is a relationship between the presence of magnetotactic bacteria in recent and ancient sediments and some specific environmental characteristics. In this sense, this project aims to obtain a high resolution sedimentary record in areas of the continental shelf, reefs and ocean bottoms that present high levels of current primary production (resurgence zone), and analyze, using a multi-proxies ) the decadal and / or secular variability of biological productivity. Among these are a large number of oceanographic parameters (oxygen, nutrients and methane) related to water bodies and their chemistry in the variations during the day and during the year. In relation to this, together with paleomagnetic analyzes there is a series of multidisciplinary ancillary analyzes (elements, minerals, associations of microphysses) that need to be coupled to understand the causes of the presence of magnetotatic bacteria in recent sediments. In relation to the isolation of recent bacteria, it is essential to detect magnetotactic bacteria in water and sediment samples; (2) to analyze the phylogenetic morphology and diversity of magnetotactic bacteria; (3) isolating magnetotactic microorganisms using specific culture media; (4) characterize the magnetotamic microorganisms with electron microscopy with special interest in the size, shape and composition of their magnetosomes.
