Production of bio-based adipic acid using a combination of engineered Pseudomonas putida strains
(2024) In Sustainable Chemistry for the Environment 8.- Abstract
- Adipic acid is an industrially important dicarboxylic acid and an
essential precursor in the synthesis of Nylon-6,6. Due to the
environmental impact associated with the current synthetic methods for
Nylon-6,6 production, greener alternatives based on renewable and
bio-based feedstocks are needed. In the present study, the potential of
two Pseudomonas putida strains engineered for muconic acid
accumulation was used to produce adipic acid from the lignin-derived
aromatic compound guaiacol. This was achieved by expressing genes
enabling the conversion of guaiacol to catechol in the first strain, and
the conversion of muconic acid to adipic acid via expression of the Bacillus... (More) - Adipic acid is an industrially important dicarboxylic acid and an

the conversion of muconic acid to adipic acid via expression of the Bacillus coagulans
enoate reductase gene in the second strain. Through process
engineering, a 2-step production was designed in which 2.93 mM
bio-adipic acid was produced, with a yield of 0.57 mol/mol. This is the
first demonstration that process and strain engineering can be combined
to obtain a complete bio-based route for adipic acid production from
depolymerized lignin compounds using the robust P. putida chassis. (Less)
