Biobutanol as an alternative type of fuel

Butanol is an alternative type of fuel. Amid the depletion of the world’s (accessible) petroleum reserves, butanol is considered to be a potential energy source. Although butanol production was initially associated with microbiological synthesis, on an industrial scale, butanol is produced via chemical synthesis. For its production to become economically viable, strains of microorganisms must have a potential for excessive synthesis of butanol. The pathways of butanol synthesis via microorganisms and their regulation, as well as the most promising producer strains for industrial production and methods for increasing their productivity, are discussed in the survey.
