Microbial natural products have been an important traditional source of valuable antibiotics and other drugs but interest in them waned in the 1990s when big pharma decided that their discovery was no longer cost-effective and concentrated instead on synthetic chemistry as a source of novel compounds, often with disappointing results. Moreover understanding the biosynthesis of complex natural products was frustratingly difficult. With the development of molecular genetic methods to isolate and manipulate the complex microbial enzymes that make natural products, unexpected chemistry has been revealed and interest in the compounds has again flowered. This two-volume treatment of the subject wi...
This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.
Bacterial cells are encased in a cell wall, which is required to maintain cell shape and to confer physical strength to the cell. The cell wall allows bacteria to cope with osmotic and environmental challenges and to secure cell integrity during all stages of bacterial growth and propagation, and thus has to be sufficiently rigid. Moreover, to accommodate growth processes, the cell wall at the same time has to be a highly dynamic structure: During cell enlargement, division, and differentiation, bacteria continuously remodel, degrade, and resynthesize their cell wall, but pivotally need to assure cell integrity during these processes. Finally, the cell wall is also adjusted according to both...
This book provides in-depth insights into the biology, taxonomy, genetics, physiology and biotechnological applications of Actinobacteria. It especially focuses on the latter, reviewing the wide variety of actinobacterial bioactive molecules and their benefits for diverse industrial applications such as agriculture, aquaculture, biofuel production and food technology. Actinobacteria are one of the most promising sources of small bioactive molecules and it is estimated that only a small percentage of actinobacterial bioactive chemicals have been discovered to date. Identifying new diverse gene clusters of biotechnological relevance in the genome of Actinobacteria will be crucial to developing advanced applications for pharmaceutical, industrial and agricultural purposes. The book offers a unique resource for all graduate students, researchers and practitioners in the fields of microbiology, microbial biotechnology, and the genetic engineering of Actinobacteria.
With lessons learned from COVID-19, a world-leading expert on pandemic preparedness proposes a pragmatic plan urgently needed for the future of global health security. The COVID-19 pandemic revealed how unprepared the world was for such an event, as even the most sophisticated public health systems failed to cope. We must have far more investment and preparation, along with better detection, warning, and coordination within and across national boundaries. In an age of global pandemics, no country can achieve public health on its own. Health security planning is paramount. Lawrence O. Gostin has spent three decades designing resilient health systems and governance that take account of our int...
A case-study of the growth of the SA (or stormtroopers) in Weimar Germany.
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, whil...
Received document entitled: APPENDIX TO PETITION FOR WRIT
Nicht noch eine Geschichte über einen Neuanfang! Denn Johanna findet, dass Neuanfänge etwas für Loser sind. Deswegen tut sie ehrgeizig alles dafür, dass bei ihr alles nach Plan läuft: Ein Job als Projektmanagerin, eine Hamburger WG mit der besten Freundin der Welt und ein Freund, mit dem sie den Rest ihres Lebens verbringen möchte. Leider ist ein perfektes Leben aber vor allem eins: Anstrengend. Als Johanna am Ende ihrer Kräfte ist, bleibt ihr nichts anderes übrig, als doch einen Neuanfang zu wagen. Statt als Aussteigerin an einem paradiesischen Strand landet sie aber nur eine Stunde außerhalb von Hamburg auf dem Dorf. Dort lernt Johanna, dass sie ein ungeahntes Talent hat: Das Springreiten. Sie und die neurotische Stute Carrie werden ein unschlagbares Team und schon bald verfolgt Johanna wieder mit aller Kraft ein ehrgeiziges Ziel: Die Teilnahme am Hamburger Springderby. Aber ist es das, was sie wirklich will? Zum Glück findet sie in ihrem neuen Leben auch neue zwei- und vierbeinige Freunde, die ihr helfen, das herauszufinden.
