Actinomycetes are a group of Gram-positive bacteria of which many representatives are prominent for being prolific producers of bioactive natural products including antibiotics, fungicides, antitumor agents, or immunosuppressants. SARP transcriptional regulators are widely distributed among actinomycetes, especially in streptomycetes and are known to activate antibiotic biosynthesis. The set of genes responsible for the production of natural products, including pathway specific transcriptional regulators such as SARPs, are typically located in contiguous regions of the genome known as "biosynthetic gene clusters" (BGCs). In this book, Oona Rössler reports on the activation of antibiotic BGCs in selected actinomycetes strains upon heterologous expression of the SARP-type regulator PapR2 from Streptomyces pristinaespiralis. Applying a bioinformatic screening for the abundance of SARP genes and SARP consensus sequences as part of BGCs, the author has selected actinomycetes candidate strains from the DSMZ strain collection for heterologous SARP expression. It is shown that overexpression of papR2 increased the production of predominantly unknown antimicrobial compounds in more than half of the selected actinomycetes strains, as observed by bioassays against different microbial test strains including bacteria and fungi. About the author Oona Rössler performed her Master Thesis at the Leibniz Institute DSMZ, German Collection of Microorganisms and Cell Cultures.

This volume brings together leading international experts to offer a unique and timely perspective on geomicrobiology through their latest research and findings. Chapters address interactions of marine and freshwater microorganisms contributing to geochemical cycles, including biochemical mechanisms for mineralization and transformation of solid minerals and dissolved metals. In addition, the resilience and physiological elasticity of specific bacteria in extreme environments is discussed, such as mechanisms of metal homeostasis and electrochemistry involving extracellular electron flow. Further coverage includes resource recovery (metals, minerals) using microbial-driven processes and technologies, with the aim to contribute to a better understanding of microbial potential within the framework of circular economy. This book is designed for professionals and students, including environmental engineers, microbiologists, and individuals studying the interaction of bacteria with metals and minerals in the environment. It is also a resource for students in academic programs or short courses focused on bacterial diversity in the environment, systems of bacterial energetics, resource recovery, and bacterial activities in extreme or nutrient-stressed environments. .
