Strain Engineering for Butanediol

Online Inquiry

CD Biosynsis has built an advanced synthetic biology platform with the ability to help our customers achieve breakthroughs in the enhanced microbial production and the cell-free production of butanediol. We combine genetic engineering, metabolic engineering, and cell-free synthetic biochemistry to achieve high titer and high yield production of butanediol to meet the needs of diverse industries.

Advantages of Synthetic Biology-Driven Butanediol Production

Butanediol (BDO) with the molecular formula C4H10O2 refers to all the isomers of butylene glycol. BDO is an important organic compound that is widely used in different industries. Petroleum-derived BDO produced from substrates such as acetylene and propylene, is mainly produced via catalytic hydrogenation, which is a tedious and difficult process. Coupled with the instability of these substrates and the fact that the petroleum-based production is a costly process, there is a need to develop a commercial process for the biological production of alternatives to petroleum-derived BDO from renewable resources. The emerging enabling technologies and synthetic biology-inspired strategies allow the redesign, engineering, and optimization of novel biological pathways, enabling the modular development of engineered microorganisms for successful sustainable biological production of butanediol.
