Beyond being the most important natural compound source, actinomycetes are the origin of up to two-thirds of all clinically used antibiotics. Currently, new antimicrobials are urgently needed, as infections caused by antibiotic-resistant pathogens are on the rise. In the identification of new antibiotics, many scientists are currently investigating biosynthetic aspects of antibiotic production in actinomycetes. Since the emergence of next-generation sequencing technologies, the field of antibiotics research has experienced a remarkable revival. These bacteria have the potential to produce more antibiotics than previously thought possible. Some antibiotics are produced in standard media, while others require the presence of a specific signaling molecule in the medium. Others, however, are only produced when the native regulation of the biosynthesis gene cluster is overruled. This book covers topics in the field of antibiotic-producing actinomycetes. The following tops are addressed: - Approaches to access novel antibiotic producers for novel natural compounds - Omics and genome mining approaches for the discovery of novel natural compounds - Analyses and genetic engineering of antibiotic biosynthesis - Regulation of the secondary metabolism in actinomycetes

In recent years, marine genomics has become a growning rapidly field, helped by the large amount of information that is becoming available to the international scientific community. Taking into account the current excitement in the field of marine biotechnology, this Special Issue entitled “Genome Mining and Synthetic Biology in Marine Natural Product Discovery” aims to to assess the impact of these molecular approaches on the discovery of bioactive compounds from marine organisms. The term “genome mining” is used to identify all bioinformatic investigations aimed at detecting the biosynthetic pathways of bioactive natural products and their possible functional and chemical interactions. Several studies are now reporting on marine organisms. Oceans cover nearly 70% of the Earth’s surface and host a huge ecological, chemical, and biological diversity. The natural conditions of the sea favor, in marine organisms, the production of a large variety of novel molecules with great pharmaceutical potential. Marine organisms are unique in their structural and functional features compared to terrestrial ones. Innovation in this field is very rapid, as revealed by the funding of several Seventh Framework Programme (FP7) and Horizon 2020 projects under the topic “Blue Growth”, with the urgent goal of discovering new drugs.

Technology: general issues --- genome mining --- global regulator --- LaeA --- overexpression --- Penicillium dipodomyis --- sorbicillinoids --- ulvan-derived oligosaccharides --- ulvan lyase --- heterologous expression --- polysaccharide lyase family 25 --- whole-genome sequencing --- docosahexaenoic acid (DHA) --- polyunsaturated fatty acid --- fatty acid synthesis pathway --- polyketide synthase pathway --- bacteria --- fungi --- natural products --- synthetic biology --- microalgae --- monogalactosyldiacylglycerol synthase --- UDP-sulfoquinovose synthase --- sulfoquinovosyltransferase --- monogalactosyldiacylglycerols --- sulfoquinovosyldiacylglycerols --- transcriptome analysis --- genome mining --- global regulator --- LaeA --- overexpression --- Penicillium dipodomyis --- sorbicillinoids --- ulvan-derived oligosaccharides --- ulvan lyase --- heterologous expression --- polysaccharide lyase family 25 --- whole-genome sequencing --- docosahexaenoic acid (DHA) --- polyunsaturated fatty acid --- fatty acid synthesis pathway --- polyketide synthase pathway --- bacteria --- fungi --- natural products --- synthetic biology --- microalgae --- monogalactosyldiacylglycerol synthase --- UDP-sulfoquinovose synthase --- sulfoquinovosyltransferase --- monogalactosyldiacylglycerols --- sulfoquinovosyldiacylglycerols --- transcriptome analysis
