Case Study

Biosynthetic Pathway of Ethyl Butyrate by Saccharomyces Cerevisiae

Ma Y, et al. Journal of agricultural and food chemistry, 2020, 68(14), 4252-4260.

Ethyl butyrate is one of the important components of daily chemical flavors and food fragrances. Using alcohol acyltransferase-modified Saccharomyces cerevisiae as a catalyst to catalyze the reaction of butyryl-CoA and ethanol, the biosynthetic pathway of ethyl butyrate can be achieved.
Biosynthetic pathway of ethyl butyrate
· The butyryl-CoA synthesis pathway from C. acetobutylicum has been engineered to produce butanol and butyric acid in S. cerevisiae as well as in other hosts, including E. coli, Kluyveromyces marxianus, etc.
· To construct pathways for producing butyryl-CoA, two endogenous genes, MCT1 and Erg10, which can produce acetoacetyl-CoA from acetyl-CoA, and three exogenous genes, Hbd, Bcd, and Crt from C. acetobutylicum, were cloned.
· These five genes were overexpressed in the wild-type strain (AY14α) under the action of the strong promoter PGK1p and terminator PGK1t. Two engineered strains, EB (Hbd, Crt, Bcd, Erg10) and MB (Hbd, Crt, Bcd, MCT1), were obtained.
· After fermentation, the results showed that ethyl butyrate was produced by the modified strains EB and MB, but the production was low, approximately 1.76±0.34 mg/L and 1.09±0.12 mg/L, respectively.

Transesterification Reaction of Ethyl Butyrate with Methanol for Catalytic Activity Evaluation

Albuquerque M C G, et al. Journal of Molecular Catalysis A: Chemical, 2009, 300(1-2): 19-24.

The transesterification of ethyl butyrate with methanol can be used as a model reaction to evaluate the potential of catalysts in triglyceride transesterification for biodiesel production. A series of MgO/CaO catalysts were prepared with different molar ratios. The results show that when the Mg:Ca molar ratio is 3, the catalytic activity of the transesterification reaction is the highest, with a conversion rate of nearly 60%.
Catalyst activity assessment in transesterification reactions
· The transesterification reaction was performed in a glass bath reactor with a water-cooled condenser. The experimental conditions were: reaction temperature of 333 K, inert atmosphere (nitrogen), stirring rate of 1250 rpm and 1 h reaction time. Prior to the reaction, the catalysts were activated at 1073 K for 1 h (heating rate, 10 K/min) under He flow.
· After cooling, the catalyst was added to the reaction mixture keeping the He flow. The reaction was stopped by submerging the reactor in an ice bath. The catalyst was separated by filtration, and the reaction products were analyzed in a gas chromatograph.
· Finally, the degree of lixiviation of CaO/MgO samples was evaluated by contacting the catalyst with methanol under the same experimental conditions as used in the transesterification process, except for the presence of ethyl butyrate.
