Abstract

The remains of the monastery of San Quirico stand on the slopes of Poggio Tondo, a hill not far from the ancient city of Populonia. They overlook the Tyrrhenian Sea, dotted with the islands of the Tuscan archipelago. Field research at this site, carried out in the first decade of the new millennium by two different teams, from Siena University and Venice’s Ca’ Foscari University, respectively, was part of ongoing efforts to expand the Baratti-Populonia Archeological Park, and to further explore the features present within it. This volume contains the results of this research work: a scientific publication of the excavation, and a critical analysis of the material found. Processing of the data collected during these investigations, together with a re-reading of written documentation, has made it possible to piece together the complex history of this important monastery, in a totally new narration. In this narration, the history of the monastery, and of the features which existed prior to it, are closely interwoven with the history of the promontory of Populonia and the surrounding area, ultimately producing a new overview which sets out the historical boundaries of this area, between Late Antiquity and the modern era.

Abstract

Biosurfactants are structurally diverse group of bioactive molecules produced by a variety of microorganisms. They are secondary metabolites that accumulate at interfaces, reduce surface tension and form micellar aggregates. This research topic describes few novel microbial strains with a focus on increasing our understanding of genetics, physiology, regulation of biosurfactant production and their commercial potentials. A major stumbling block in the commercialization of biosurfactants is their high cost of production. Many factors play a significant role in making the process cost-effective and the most important one being the use of low-cost substrates such as agricultural residues for the production of biosurfactants. With the stringent government regulations coming into effect in favor of production and usage of the bio-based surfactants, many new companies aim to commercialize technologies used for the production of biosurfactants and to bring down costs. This Research Topic covers a compilation of original research articles, reviews and research commentary submitted by researchers enthusiastically working in the field of biosurfactants and highlights recent advances in our knowledge of the biosurfactants and understanding of the biochemical and molecular mechanisms involved in their production, scale-up and industrial applications. Apart from their diverse applications in the field of bioremediation, enhanced oil recovery, cosmetic, food and medical industries, biosurfactants can also boast off their unique eco-friendly nature to attract consumers and give the chemical surfactants a tough competition in the global market. This biosurfactant focused research topic aims to summarize the current achievements and explore the direction of development for the future generation of biosurfactants and bioemulsifiers. Some of the biosurfactant optimization processes presented are well-structured and already have a well-established research community. We wish to stimulate on-going discussions at the level of the biosurfactant production including common challenges in the process development, novel organisms and new feedstock and technologies for maximum benefit, key features of next generation biosurfactants and bioemulsifiers. We have compiled the research outputs of international leaders in the filed of biosurfactant particularly on the development of a state-of-the-art and highly-efficient process platform.

Abstract

The cell surface of fungi, bacteria and sea organisms is highly glycosylated. These glycans are oligo- or polysaccharide molecules that can be secreted or attached to protein or lipids forming glycoconjugates. They present extraordinary structural diversity that could explain their involvement in many fundamental cellular processes, including growth, differentiation and morphogenesis. Considerable advances have been made on the structural elucidation of these glycans. Their primary structures were determined based on a combination of mass spectrometry and NMR spectroscopy techniques. The combination of these sensitive and powerful techniques has allowed us to increase our structural knowledge of a wide variety of glycans expressed by different fungi, bacteria and sea organisms.

Abstract

This book is a new history of an ancient geography. It reassesses the evidence for why Europeans believed a massive southern continent existed, and why they advocated for its discovery. When ships were equal to ambitions, explorers set out to find and claim Terra Australis. Antipodes charts these voyages—voyages both through the imagination and across the High Seas—in pursuit of the mythical Terra Australis. In doing so, the question is asked: how could so many fail to see the realities they encountered? And how is it a mythical land held the gaze of an era famed for breaking free the shackles of superstition? That Terra Australis did not exist didn’t stop explorers pursuing the continent, unwilling to abandon the promise of such a rich and magnificent land till it was stripped of every ounce of value it had ever promised. In the process, the southern continent—an imaginary land—became one of the shaping forces of early modern history. Includes 48 pages of b&w and colour images.
