Butyric acid is an important raw material in various industries including chemistry, food, cosmetics and pharmaceutics. It has also become an increasingly attractive in the field of renewable energy in case of production from bio-based natural ingredients due to the depletion of non-renewable resources. Brown algae is a good substrate in Korea that can be grown and obtained easily from the seas surrounding Korea. In this study, butyrate was produced from a model compound, glucose, in clostrial growth medium (CGM) using Clostridium tyrobutyricum ATCC 25755 in fed-batch fermentation at pH 6.0 and 37℃. In this process the total butyrate obtained was higher than 50 g/L. Then, brown algae were used as substrates for butyrate fermentation. So far 7 g/L of butyrate was produced from Laminaria japonica, one of the well-known brown algae, further experiment is going on to explore the optimal condition for butyrate fermentation. This result showed the possibility of the usage of brown algae as substrate to produce butyric acid.
