Project Description

The transition to a low carbon, bio-based economy is dependent upon our ability to produce speciality and platform chemicals efficiently from microorganisms via industrial biotechnology. This multidisciplinary project will develop a novel, improved and holistically engineered process for the microbial production of 2,3- butanediol. 23BD is currently obtained via petrochemical processes and is an important platform chemical used for the production of methyl ethyl ketone, a solvent, and butadiene, which is in turn used in the production of synthetic rubber [1,2]. To address this challenge a joint synthetic biology and process engineering approach will be used to increase 23BD production by developing a scalable bioprocess. The research will focus on the following areas; 1 - Scalable bioreactor process design for 23BD production 2 - Strain modification based on measured bioreactor performance 3 - Process modelling and optimisation.

As a starting point this project will make use of previously developed 23BD producing S. cerevisiae strains [3], which divert carbon to 23BD via acetoin due to an accumulation of pyruvate and acetaldehyde and apply a rigorous bioprocessing approach and experience of bioprocess design based on modified S. cerevisiae strains [4,5] to test strain behaviour at in bioreactors and design a scalable fed batch/continuous 23BD production process.

The increased knowledge of bioprocess design optimisation arising from this project will be applicable to industrial biotechnology across a broad range of systems.
