The term fermentation derived from the Latin verb fevere (boil) used by humans for the production of food and beverages since the Neolithic age is the oldest of all biotechnological processes. The fermentation process used in the production of antibiotics, alcohol, bread, vinegar and other food or industrial products differs from respiration in that organic substances rather than molecular oxygen are used as electron acceptors. After successful microbial fermentation processes on microbial cells (biomass), microbial enzymes, microbial metabolites including antibiotics, and other fermented foods, currently more than 3500 different fermented foods are consumed by humans worldwide. The potential of fermentation techniques was dramatically increased in the late 1960s and 1970s through achievements in molecular genetics, cell fusion, and enzyme technology. However, additional completely novel, powerful techniques such as genetic engineering via recombinant DNA technology in 1973 and hybridoma technology (monoclonal antibody) in 1975 were responsible for the current biotechnology boom.
In genetic engineering, a known gene is inserted into a microbial, animal, or plant cell in order to achieve a desired trait for the overproduction of target compounds, but microorganisms have played a major role in the development of biotechnology. This is due to the rapid growth of microbes, cheap growth media, massive diversity in the metabolite types and easy of genetic manipulation. However, mass culture of animal cell lines is also important to manufacture viral vaccines and other therapeutic recombinant products such as enzymes, hormones, immunologicals (monoclonal antibodies, interleukins, lymphokines, etc), and anticancer agents. Mammalian cells cultivated in bioreactors have surpassed microbial systems for producing therapeutic recombinant proteins because of their capacity for proper protein folding, assembly and post‐translational modification. Major therapeutic recombinant proteins are successfully commercialized, but expensive animal free media, cost of production in large scale with low yield (the tens‐of‐milligrams/liter), microbial contamination, and gene regulation are the important issues to be resolved. Other cell culture research is also underway to produce such complex therapeutic proteins in insect cell (baculovirus) or in higher plants. Molecular biopharming using transgenic animals such as goat and pig for rDNA proteins have also successfully commercialized.
Fermentation technology for the production of compounds that find application in food, biochemical, biomaterial, bioenergy, pharmaceutical sectors encompasses a broad field, not only including (1) conventional microbial and enzyme systems, (2) genetic and metabolic engineering, along with systems biology/synthetic biology, and genome editing, but also including (3) mammalian cell and plant cell systems. Despite a long history of fermentation processes for generations, the requirement for sustainable production of bioenergy and biomaterials is also demanding innovation and development of novel fermentation concepts. Continued introduction of new technology in cell culture systems demands innovation in new bioreactor process development and scale up processes for cell factory potential.
This book reflects this transition from traditional fermentation technology to new cell fermentation technology, that provides equal emphasis on microbial, mammalian as well as plant cell technologies for new and improved processes and products in today's biochemical process industry.
Currently two fermentation textbooks available on the market (1999) are outdated and do not deal with current progress in fermentation and cell culture technologies and commercial recombinant bioproducts. Most other edited volumes are the work of multiple contributors and normal didactic criteria for explanation of evolving new techniques and applications are lacking. Experience in teaching this subject has made clear that the basic concepts and essential features have not been covered in a typical science curriculum. The primary objective of writing this book is to relate the food fermentation and cell culture biopharmaceutical actives using different expression hosts. Product diversity makes fermentation technology a multi ‐disciplinary expertise associated with microbiology, organic chemistry, biochemistry, and molecular biology. Remarkable advances in these areas will help to lift people out of wretched and empower them with new knowledge. The subject matter is divided into Part V, including microbiology, biotechnology, molecular biology, biochemical engineering, and global market size of bioproducts, and their applications.
Part I covers microbial cell technology and culture tools (including classical strain improvements and tools) and modern strain improvement and tools (genome shuffling, recombinant DNA technology, RNA interference (RNAi) and CRISPR)/Cas technology for genome editing; also includes molecular thermodynamics for biotechnology, protein engineering, genomics, proteomics and bioinformatics, systems/synthetic biology and metabolic engineering, quorum sensing and quenching. Other bioengineering and scale‐up processes and new bioprocesses of fermentation such as growth‐arrested bioprocess, integrated bioprocess, and consolidated bioprocessing (CBP) are included.
Part II deals applications of microbial fermentation to food products (dairy, meat/fishes, vegetable/cereals), organic acids, food ingredients, chemicals, and pharmaceuticals. Food products/ingredients included flavors and amino acids, sweeteners, vitamins and pigments, microbial polysaccharides/biopolymers, bacteriocins and bacteriophages, enzymes, biomass (SCP)/mushrooms, functional foods and nutraceuticals such as probiotics and prebiotics, and microbiome. Others included alcoholic beverages and other fermentation chemicals (bioethanol, biobutanol/biobutandiol, biodiesel, biomethane, biohydrogen). In final section, pharmaceuticals such as antibiotics, antibiotic growth promoters, antitumor drugs, steroids/statins, and biopesticides included.
Part III covers (i) animal cell technology including animal cell culture, bioprocessing, strain development, applications (monoclonal antibodies, different vaccines (DNA vaccines, edible vaccines, zika vaccines, hepatitis vaccines, HIV vaccines, COVID 19 vaccines), and (ii) transgenic animal bioreactors, and applications in animals and fishes, etc. Part IV on plant cell technology covered plant tissue and cell culture and applications, bioreactor types (seed‐based bioreactor, plant cell suspension bioreactor, hairy root bioreactor, chloroplast bioreactors) and modern plant breeding or biotech/GM crops and their applications.
Finally, Part V deals with safety issues of new biotechnologies on microbial, animal, and plant cells.
This book aims to give readers, general science students, researchers, and industrial practitioners as well as instructors, an overview of the essential features of advanced fermentation and cell culture technology. I would like to thank my students, post‐docs, and former colleagues at McGill University (Canada), Jiangnan University (China) and Kangwon National University (Korea), who, for the past 37 years, have helped and suggested me in teaching this subject course.
Among the over hundres of my former graduate students and post‐docs, I would like to dedicate this book specifically to my beloved former students, Dr. Young J. Choi and Dr. Marcio Belem in Montreal, whom both passed away suddenly.
Last but not least, I must thank my wife Young for her love and encouragement, together with the patience of my sons, Edward and his family (wife Maria, son Maxim) in Toronto and David and his family (wife Ronit, daughter Romy) in Santa Monica, California during the preparation of this volume.
