Our leadership team has over a century of combined biotechnology, biochemistry and biofuels experience, with more than 400 million gallons of bio-based products brought onto the market by our team. Our patents and our proprietary know-how will allow us to generate butyric acid and butanol from a variety of renewable biomass sources. Our focus is on lignocellulosic biomass, including wood, prairie grasses, bagasse, and corn stover as well as low cost sugar crops such as sweet sorghum, sugar beets and corn.

Science Advisory Team:

David Ramey / Founder and Scientific Advisor

David Ramey is the founder of butylfuel™ LLC and a scientific advisor to the company. David received the "Technologist of the Year" award in 1996 from the Ohio Academy of Science for his pioneering efforts to bring organically derived butanol to the market.

He has twenty years of extensive experience in fermentation and has worked with closely with Dr. Yang of the Ohio State University on a number of DOE-STTR and USDA-SBIR projects. David is a physicist by training with degrees in physics from San Diego State University.

In 2005, Mr. Ramey demonstrated the efficacy of biobutanol as a motor fuel to replace gasoline when he traveled the country in an unmodified car fueled with pure butanol to promote the advantages of biobutanol. He proved, for the first time, that biobutanol was equal to gasoline.


Dr. S.T. Yang / Scientific Advisor

Dr. S.T. Yang is a Professor of Chemical & Biomolecular Engineering, Biochemistry Graduate Program, and Food Science & Technology at The Ohio State University.

Dr. Yang has been involved in bioprocessing research for more than 25 years, and has 10 related patents. He is a world-renowned expert on Clostridium organisms and high-rate fermentation. During his 25 years at OSU, Dr. Yang has supervised many research projects on novel processes for value-added products from food wastes, including metabolic engineering of anaerobic bacteria for butyric acid and butanol production, extractive fermentation for production of carboxylic acids, and novel bioreactor design and process scale up.

Dr. Yang received his Ph.D. degree from Purdue University (1984) and has published more than 150 journal papers, proceeding articles, and book chapters.


Dr. Teddy Ezeji / Scientific Advisor

Dr. Thaddeus (Teddy) Ezeji is an Assistant Professor of Microbiology & Biotechnology in the Department of Animal Sciences at The Ohio State University and is a member of the Ohio State Agricultural and Development Center (OARDC).

Dr. Ezeji has extensive experience in lignocellulosic biomass processing and development, production, purification and process development of materials for bioenergy and bioproducts. His expertise is uniquely valuable to BF, including his expertise in development of new microbial strains that are capable of utilizing mixtures (pentose and hexose sugars) of lignocellulosic derived sugars and are resistant to microbial inhibitors present in the lignocellulosic hydrolysates. Dr. Ezeji's laboratory is also engaged in research activities on anaerobic digestion, probiotic, metabolomics, genetic and metabolic engineering of solventogenic (butanologenic) clostridia.

He received his Ph.D. in Microbiology from University of Rostock, Germany in 2001 and serves on the editorial boards for World Journal of Microbiology and Biotechnology, African Journal of Food Science, and the Continental Journal of Microbiology.
