Scientific Officer of BioBench LLC, a contracting facility for purification and fermentation development in Seattle, USA Gus started the company in 2011 and is now pursuing this full time BioBench’s primary focus is initial development for product screening and vaccine Phase I clinical trials Moulton has more than 20 years of process development experience in the biotechnology community During the last 13 years he has been responsible for setting up and running fermentation labs to generate medium to high cell density fermentations He performed these services for both Corixa Corporation, a former cancer vaccine company bought by GlaxoSmithKline plc, and the Infectious Disease Research Institute (IDRI), a nonprofit organization which develops diagnostic tests and vaccines to diagnose and treat diseases in third-world countries, such as India, Brazil and in Africa During Moulton’s career at Corixa he was initially responsible for purification development of the most critical antigens, and subsequently for setting up and developing recombinant E coli fermentation processes at the 30 liter scale for Phase I clinical vaccine trials for HER2/neu He also developed an upstream and downstream process for the purification of the recombinant antigen TcF to be used in the diagnostic test for Chagas disease The upstream process was designed per GLP standards for in-house use, while the downstream process was designed for and successfully transferred to Viral Antigens, Inc xi Fed-batch fermentation During Moulton’s tenure at IDRI he again set up a fermentation lab for development of recombinant E coli production of foreign antigens Most fermentation development work Moulton performed at IDRI was for vaccine development against leishmaniasis – a disease caused by protozoan parasites of the genus Leishmania and transmitted by the bite of certain species of the sand fly (subfamily Phlebotominae) – and tuberculosis caused by Mycobacterium tuberculosis While at IDRI, Moulton developed a unique feed recipe in which he supplemented phosphate for a recombinant E coli fermentation using rich media that tripled the final cell density without any significant increase in process cost or time Moulton also developed an M smegmatis recombinant system that should easily be scalable using a wave reactor This project can be used to produce Mtb antigens for both diagnostics and vaccine development Over the last 13 years Moulton has successfully developed over 30 fermentation processes xii Introduction to fermentation DOI: 10.1533/9781908818331.1 Abstract: The use of yeast or microbial cells for the production of a foreign protein has changed the approach of medical research to finding healthcare solutions The application of recombinant systems has become mainstream in treatment of disease One of the most important aspects of this new scientific discipline is the ability to design a cell line or strain, in the case of bacterial or yeast recombinant systems that can be grown under controlled conditions, to produce significant quantities of a recombinant protein Recently, E coli has been the predominant bacteria in research and production laboratories and plays a key role in the development of modern biological engineering and industrial microbiology, enabling foreign proteins to be produced in a prodigious and cost-effective way This type of cell growth and production is called fermentation and its history and use will be discussed along with current developments and applications of recombinant technology Key words: E coli,
