Abstract

For over twenty years now, the agri-foodstuffs sector has been marked by an ongoing revaluation of the typical product. Such products encompass an increasingly intangible value connected, not only with their intrinsic qualities, but also with what is evoked by the production methods and the context from which they originate. The typical product is identified by a decided stability in the features, deriving from the concentration of a major historic tradition in geographically small territories by a relatively restricted human group. As a result, in general, the local identity tends to predominate over the image of the firm. This accentuates the most significant strategic phenomenon: the collaboration between direct competitors implemented by the producers.

Abstract

Minerals are very significant components of coal from both academic and practical perspectives. Minerals may react when the coal is burned, either forming an ash residue, or, in many cases, releasing volatile components, or being needed to be removed as slag from the blast furnace during metallurgical processing. Minerals in coal can also be a source of unwanted abrasion, stickiness, corrosion, or pollution associated with coal handling and use. Minerals in coal, in some cases, are major carriers of valuable metals, such as Ga, Al, and rare earth elements, and these coals with highly-evaluated valuable metals have the potential to be raw sources for industry use. From the genetic point of view, the minerals in coal are products of the processes associated with peat accumulation and rank advance, as well as other aspects of epigenetic processes, and, thus, the minerals in coal can provide information on the depositional conditions and geologic history of individual coal beds, coal-bearing sequences, and regional tectonic evolution. This Special Issue, “Minerals in Coal”, focuses on providing an up-to-date series of papers, covering research and technological developments in the nature, origin, and significance of the minerals in coal, and productions derived from combustion and gasification.

Abstract

Fungal natural products are friends and foes of humans such as deleterious mycotoxins, cytotoxic, carcinogenic compounds or beneficial compounds such as antibiotics, fungicides, insecticides, antiviral and antitumor metabolites. Understanding fungal diversity and estimation of fungal species on our planet poses a great challenge to researchers. This complexity is further multiplied by secondary metabolite diversity of fungi, which requires interdisciplinary studies. It is extremely important to understand the fungal secondary metabolism to stop human, animal and plant diseases caused by fungi and harvest their valuable metabolites. Furthermore, many secondary metabolite gene clusters are silenced under laboratory conditions. It is vital to develop effective methods to activate those clusters in order to discover novel potent metabolites. This e-book is a compilation of original review articles contributed by leading fungal secondary metabolite researchers with a wide range of expertise. Important aspects of fungal secondary metabolism, including regulation, genome mining, evolution, synthetic biology and novel methods have been discussed. This book will be a great source to those people, who are interested in understanding overall structure, diversity and regulation of production of these tiny but precious chemicals.

Abstract

Algae biomass has enormous potential to produce fuels and value-added products. Algae-derived biofuels and bioproducts offer great promise in contributing to U.S. energy security and in mitigating the environmental concerns associated with conventional fuels. Algae’s ability to grow in low quality water/wastewater and to accumulate lipids has encouraged scientists to investigate algae as a medium for wastewater treatment and a potential source of fuel and bioproducts. There are growing demands for biomass-based transportation fuels, including biodiesel, bio-oil, biomethane, biohydrogen, and other high-value products (nutraceuticals, proteins, omega-3 etc.). Algae can help address these needs. The topic of algae energy includes the production and characterization of algae cultures, conversion into fuel feedstocks and high value products, and optimization of product isolation and use. In view of the increasing efforts in algae biomass production and conversion into energy and high-value products, the current research topic covers important aspects of algal strain selection, culture systems, inorganic carbon utilization, lipid metabolism and quality, biomass harvesting, extraction of lipids and proteins, and thermochemical conversion of algal feedstocks into biocrude.

Abstract

Livestock species are either herbivores or omnivores that are maintained largely on plant-based diets. We have long appreciated the importance of understanding dietary plants from both nutritional and agronomic perspectives. However, it is increasingly clear that the fungi, bacteria and other microorganisms that live in the plants and animals are also significant factors in the ecology of agricultural animals. Many of the effects exerted on animals by dietary plants are attributable to secondary metabolites produced by the plants themselves or commensal microorganisms. Some fungal and plant secondary metabolites have multiple biological effects. We must be careful not to categorize a plant as strictly beneficial or harmful. Furthermore, we must be careful not to categorize even a particular plant or fungal compound as strictly beneficial or harmful. Rather, the harm or benefit of secondary metabolites are often dependent on the metabolic status of the animal, the interaction with other dietary factors including other secondary metabolites, and the dose received through the diet. This collection examines a range of agriculturally important plant and fungal products including essential oils, alkaloids, isoflavones and nitrates.

Abstract

Oceans include the greatest extremes of pressure, temperature and light, and habitats can range from tropical waters to ocean trenches, several kilometers below sea level at high pressure. With its 70% of the surface of our planet marine ecosystem still remains largely unexplored, understudied and underexploited in comparison with terrestrial ecosystems, organisms and bioprocesses. The biological adaptation of marine organisms to a wide range of environmental conditions in the specific environment (temperature, salinity, tides, pressure, radiation, light, etc.) has made them an enormous reservoir of interesting biological material for both basic research and biotechnological improvements. As a consequence marine ecosystem is valued as a source of enzymes and other biomolecules exhibiting new functions and activities to fulfill human needs. Indeed, in recent years it has been recognised as an untapped source of novel enzymes and metabolites even though, with regard to the assignment of precise biological functions to genes, proteins and enzymes, it is still considered as the least developed. Using metagenomics to recover genetic material directly from environmental samples, this biogenetic diversification can be accessed but despite the contributions from metagenomic technologies the new field requires major improvements. A few words on the complexity of marine environments should be added here. This complexity ranges from symbiotic relationships to biology and chemistry of defence mechanisms and from chemoecology of marine invasions up to the strategies found in prokaryotes to adapt to extreme environments. The interdisciplinary study of this complexity will enable researchers to find an arsenal of enzymes and pathways greatly demanded in biotechnological applications. As far as marine enzymes are concerned they may carry novel chemical and stereochemical properties, thus biocatalytically oriented studies (testing of suitable substrates, appropriate checking of reaction conditions, study of stereochemical asset of catalysis) should be performed to appropriately reveal this “chemical biodiversity” which increases interest for these enzymes. Among other biomolecules, polysaccharides are the most abundant renewable biomaterial found on land and in oceans. Their molecular diversity is very interesting; except polysaccharides used traditionally in food and non-food industries, the structure and the functionality of most of them are unknown and unexplored. Brown seaweeds synthesize unique bioactive polysaccharides: laminarans, alginic acids and fucoidans. A wide range of biological activities (anticoagulant, antitumor, antiviral, anti-inflammation, etc.) have been attributed to fucoidans and their role with respect to structure-activity relationship is still under debate. In this Research Topic, we wish to centralize and review contributions, idea and comments related to the issues above. In particular results of enzymatic bioprospecting in gross marine environment will be acknowledged along with research for structural characterization and biological function of biomolecules such as marine polysaccharides and all kind of research related to the complexity of bioprocesses in marine environments. Inter- and multi-disciplinary approach to this field is favoured in this Research Topic and could greatly be facilitated by the web and open access nature as well.

Abstract

Dear Colleagues,This Special Issue is dedicated to fungi that are found as endophytes in the world’s plants. Among many other things, it covers newly-discovered fungi that are endophytic. The role of the endophyte in the plant microbiome is of emerging interest, and aspects of are included. Secondary products of endophytes are receiving renewed attention as some have been found that are potential fuels, antibiotics, antioxidants, and anticancer agents, as well as immunosuppressive compounds. Aspects concerning the physiological/biochemical/role of the endophyte, as it relates to its host are also of interest. It goes without saying that this volume also includes aspects of the genetics and epigenetics of endophytes, especially as they relate to the host genome or the production of valuable and important products.

Abstract

This book proposes an array of 11 key papers aimed at investigating the complex and multifaceted nature of the bio-based economy, focusing both on a conceptual understanding of the transition and on the measurement issues associated with it. More specifically, the papers included in this book can be broadly divided in two groups: (1) those aiming at adding to our understanding of the transition process towards a sustainable bio-based economy; and (2) those aiming at adding to the definition and measurement of the emerging sustainable bio-based economy. The book offers a comprehensive view of the phenomenon, providing a logical framework for understanding the ongoing transition towards a bio-based economy, as well as an overview of existing tools to assess and measure it. Policy-makers will largely benefit from the book, which contributes to taking a further step towards the much-needed transition to sustainability.
