The use of biocatalysts, including enzymes and metabolically engineered cells, has attracted a great deal of attention in the chemical and bio-industry, because biocatalytic reactions can be conducted under environmentally-benign conditions and in more sustainable ways. The catalytic efficiency and chemo-, regio-, and stereo-selectivity of enzymes can be enhanced and modulated using protein engineering. Metabolic engineering seeks to enhance cellular biosynthetic productivity of target metabolites via controlling and redesigning metabolic pathways using multi-omics analysis, genome-scale modeling, metabolic flux control, and reconstruction of novel pathways. The aim of this book is to cover the recent advances in biocatalysis and metabolic engineering for biomanufacturing of biofuels, chemicals, biomaterials, and pharmaceuticals. Reviews and original research articles on the development of new strategies to improve the catalytic efficiency of enzymes, biosynthetic capability of cell factories, and their applications in production of various bioproducts and chemicals are included.

Bioengineering is a field of study that deals with the application of engineering practices to biology whereas biotechnology is a branch of applied science that uses living organisms and their derivatives to produce products and processes. Biocatalysis refers to the chemical process in which the biological catalysts or enzymes speed-up the process of reactions among organic components. Metabolic engineering aims to improve cellular biosynthetic productivity of target metabolites. This is done by redesigning and controlling metabolic pathways, through the utilization of genome-scale modeling, formation of novel pathways, multi-omics analysis and metabolic flux regulation. Biocatalysis and metabolic engineering together seek to create novel products using biological means by using genetic engineering in various microbial chassis with appropriate metabolic repertoires. This book is a valuable compilation of topics, ranging from the basic to the most complex advancements in the field of biotechnology and bioengineering. The advancements in biocatalysis and metabolic engineering have been glanced at in detail. The book will provide comprehensive knowledge to the readers.

Metabolic engineering and biocatalysis aim to produce new value-added products from biological routes through careful and deliberate genetic engineering in different microbial chassis with suitable metabolic repertoire. Hitherto, the endeavor has largely been confined to the production of new products from glucose and a few other well characterized substrates. But, as the bioeconomy gains in importance and the world seeks to explore new sources of carbon as feedstocks, a possibility exists in developing alternative C2 compounds as feedstocks in contrast to the current reliance on C6 (glucose and fructose), C5 (xylose) and C3 (glycerol) substrates. Two potential C2 alternative substrates explored in this work are ethanol and ethylene glycol. Ethanol is a biofuel whose biotechnological potential has not been fully explored. In the first part of the book, the potential of using the NADH generated from a reconstructed ethanol utilization pathway to power a biotransformation reaction is explored in Escherichia coli. Experimental results indicate that ethanol utilization delivers higher biotransformation efficiency compared to state-of-the-art glucose dehydrogenase system, which confirmed theoretical predictions of relative efficiency of the two systems. Next, the book switches attention to ethylene glycol which could be derived as breakdown products of lignocellulosic waste or from plastic waste. Here, the proposal is to demonstrate the potential of an NADH generating ethylene glycol utilization pathway that terminates at glycolate to support biocatalytic reactions in E. coli. Subsequently, the two-step ethylene glycol utilization pathway would be extended to malate and 2-phosphoglycerate to help another biotechnology workhorse, Bacillus subtilis, to grow on ethylene glycol as the sole carbon source. Different connection points to central carbon metabolism would provide a natural experiment to decipher the relative efficiencies of activating tricarboxylic acid cycle and glycolysis in supporting cell growth, and illuminate insights into the relative efficiency and evolutionary importance of different branches of metabolism in B. subtilis. Finally, ethylene glycol utilization would be combined with product formation to help B. subtilis to synthesize green fluorescent protein using flux from the C2 alternative substrate. This system would provide a platform for examining the efficacy of different ethylene glycol utilization pathways and entry points in central carbon metabolism in synthesizing amino acids and proteins. Overall, this book hopes to explore the biotechnological potential of two alternative C2 substrates (ethanol and ethylene glycol) in biocatalysis and metabolic engineering from the substrate utilization perspective.
