    Summary: This book is open access under a CC BY 4.0 license. This book defines the new field of "Bioeconomy" as the sustainable and innovative use of biomass and biological knowledge to provide food, feed, industrial products, bioenergy and ecological services. The chapters highlight the importance of bioeconomy-related concepts in public, scientific, and political discourse. Using an interdisciplinary approach, the authors outline the dimensions of the bioeconomy as a means of achieving sustainability. The authors are ideally situated to elaborate on the diverse aspects of the bioeconomy. They have acquired in-depth experience of interdisciplinary research through the university's focus on "Bioeconomy", its contribution to the Bioeconomy Research Program of the federal state of Baden-Württemberg, and its participation in the German Bioeconomy Council. With the number of bioeconomy-related projects at European universities rising, this book will provide graduate students and researchers with background information on the bioeconomy. It will familiarize scientific readers with bioeconomy-related terms and give scientific background for economists, agronomists and natural scientists alike.

    Genetic recombination was studied in Escherichia coli F- strains in which synthesis of the recA gene product protein X is increased due to mutation in either recA (tif-1) or lexA (spr). When a single donor marker was selected, the recombination proficiency of these strains was not significantly altered in Hfr crosses. However, linkage of unselected, proximal Hfr markers was found to be much reduced among the progeny tested, and more of the progeny showed evidence of multiple exchanges between donor and recipient DNA. These effects were much more apparent when the recipient carried both tif-1 and spr mutations, but in this case recombination proficiency was reduced compared with those strains carrying either mutation alone, particularly in crosses with Hfr Cavalli. A lexA mutation was found to suppress the effect of tif-1 on the recombinant genotype.
