Abstract

In this book, the authors present current research in the study of the geochemistry, composition and environmental impacts of seawater. Topics discussed include the impact of internal wave breaking on the ocean upper layer formation; trace elements in seawater in offshore oil production platform areas; self-purification of seawater; the Salton Sea megaport and seawater canal; and assessing the effect of nearshore currents over the SO2 absorption in Caribbean seawater.

Abstract

Microorganisms (bacteria, archaea, microeukaryotes) in marine environments secrete a diverse array of exopolymeric substances that facilitate attachment to surfaces, the formation of organic colloids and larger aggregations of cells (marine snow), and that can influence many ocean, as well as global, processes. The aim of this Research Topic is to highlight recent advances in the sources, chemistry and function of these microbial-produced macromolecules. We encouraged original research and reviews on exopolymeric substances, from their sources, chemico-physiological properties, functions and ecosystem effects, and including their role in the Gulf of Mexico following the Deepwater Horizon oil spill disaster.

Abstract

Planctomycetes, and their relatives within the PVC superphylum of domain Bacteria,  including verrucomicrobia and chlamydia,  challenge our classical concept of the bacterium and its modes of life and provide new experimental models for exploring evolutionary cell biology and the full diversity of how living cells can be organized internally. Unique among Bacteria they include species possessing cells with intracellular membrane-bounded compartments and a peptidoglycan-less cell wall, and bacteria such as the anammox organisms performing unique anaerobic ammonium oxidation significant for global nitrogen cycle. The book introduces these fascinating and important bacteria and deals in detail with their unusual structure, physiology, genomics and evolutionary significance.  It is a definitive summary of our recent knowledge of this important distinctive group of bacteria, microorganisms which challenge our very concept of the bacterium.

Abstract

Marine habitats are promising sources to identify novel organisms and compounds. A total of 70% of the planet’s surface is covered by ocean, and little is known about the biosphere within these habitats. In the last few years, numerous novel bioactive compounds or secondary metabolites from marine environments have been described. This is, and will be, a promising source of candidate compounds in pharma research and chemical biology. In recent years, a number of novel techniques have been introduced to the field and it has become easier to actually (bio-)prospect compounds such as enzyme inhibitors. Those novel compounds then need to be characterized and evaluated in comparison to well-known representatives. This Special Issue focuses on the description of novel enzyme inhibitors of marine origin, including bioprospecting, omic approaches, and structural and mechanistic aspects.

Abstract

The G.B. Elyakov Pacific Institute of Bioorganic Chemistry of the Far-Eastern Branch of the Russian Academy of Sciences (PIBOC FEB RAS) was founded in 1964 in Vladivostok in the Far East of Russia. Over many years, we have been carrying out studies on the natural products of both marine and terrestrial origin. In collaboration with many Russian and foreign scientists, we have investigated many hundreds of diverse biomolecules, including steroids and terpenoids, quinoid compounds and alkaloids, polysaccharides and lipids, enzymes and lectins, proteins, and peptides. The Institute has a collection of marine microorganisms (KMM) PIBOC, which includes more than 4000 strains of marine bacteria and more than 1000 strains of marine fungi. The biological activity of natural compounds is also being studied. This book includes the 14 manuscripts which covered almost all aspects of PIBOC research activity in the fields of bioorganic chemistry, biochemistry, organic synthesis of natural compounds, marine microbiology, and genetic engineering, and we hope it will provide interesting new information for scientists working in these fields.

Abstract

Essential oils extracted by the distillation or hydrodistillation of aromatic plants are a complex mixture of volatile compounds with several biological activities. Their efficacy as antimicrobial agents is related to the activity of several natural compounds belonging to different chemical families that can act both in synergy with each other and with other antibiotics. The antibiotic resistance detected among pathogens has been quickly increasing in recent years, and the control of some of these microorganisms is becoming a planetary emergency for human and animal health. The control of the microbial growth is a problem of great importance also for the food industry (food deterioration and shelf life extension) and for the world of cultural heritage (indoor and outdoor phenomena of biodeterioration). Essential oils can play an important role in this scenario, due their recognized broad-spectrum antimicrobial activity. Therefore, the main subject of this Special Issue includes an essential oil-based approach to control microrganisms in areas such as human and veterinary medicine, entomology, food industry and agriculture. In addition, the chemical composition of essential oils from endemic and rare medicinal/aromatic plants, nanoformulations of essential oils, applications in human and veterinary medicine and its use as animal feeding supplements are topics covered in this Special Issue

Abstract

This book is a collection of a group of peer-reviewed scientific papers dealing with both the evaluation and the solution of the complex but pressing problem of water source pollution. In the case of both fresh and marine water, the environmental and health protection aspects are closely linked. Monitoring activities supply continuous information on the contamination levels in inland surface, ground, and coastal waters, providing an alert in case of increased or new contamination and monitoring the effectiveness of remediation strategies. On the other hand, new or improved remediation and bioremediation tools are urgently needed to tackle the scarcity of safe drinking water. The papers in this book represent interesting starting points for future researches.

Abstract

This book presents contributions from scientists who are directly involved in the potential of marine enzymes as useful tools in biocatalysis; the results of enzymatic bioprospecting in gross marine environments are acknowledged, including two review articles on general enzymatic processes and microalgal enzymes. In addition, studies on structural characterizations, biological functions and aspects related to the complexity of marine enzyme-based bioprocesses are discussed. Prominent conclusions by many scientists in the field of marine biotechnology emphasize that, due to marine biological diversity and the specificity of biological marine metabolisms, the study of biocatalysts on a global scale from this environment is just starting, and possesses huge potential for the development of applications with industrial benefits.

Abstract

Many research teams are working to demonstrate that microorganisms can be our daily partners, due to the great diversity of biochemical transformations and molecules they are able to produce. This Special Issue highlights several facets of the production of microbial metabolites of interest. From the discovery of new strains or new bioactive molecules issued from novel environments, to the increase in their synthesis by traditional or innovative methods, different levels of biotechnological processes are addressed. Combining the new dimensions of "Omics" sciences, such as genomics, transcriptomics or metabolomics, microbial biotechnologies are opening up incredible opportunities for discovering and improving microorganisms and their production.
