This was one of three molecules for this week. To access the key intermediate (R)-citronellal used in current major industrial production routes, we established a one-pot bienzymatic cascade from inexpensive geraniol, overcoming the problematic biocatalytic reduction of the mixture of (E/Z)-isomers in citral by harnessing a . Bookshelf The reaction mixture was cooled down to room temperature, and 1 mL of water containing 0.9% (w/v) NaCl was added. It is considered for these deletion strains that the oxidation to geranic acid and citronellic acid was suppressed and, instead of it, the metabolic flow from geraniol was directed to the reduction to citronellol. Bookshelf From the result of addition of potential substrates for biosyntheses of geranic acid and citronellic acid to BY4741 culture, it was concluded that geranic acid and citronellic acid could be converted from citral and citronellal in the yeast, respectively.
