Production methods of butanol

Butanol can be obtained using chemical technologies, such as Oxo-synthesis and aldol con­densation. It is also possible to produce butanol in the process of fermentation by bacteria and butanol as one of the products called biobutanol. The most popular bacteria species used for fermentation is Clostridium acetobutylicum. Because the main products of this proc­ess containing acetone, butanol and ethanol, the fermentation is called ABE fermentation (Qureshi and Maddox, 1995).
