Scaling up and scaling down the production of galactaric acid from pectin using Trichoderma reesei [PDF]
Microbial Cell Factories, 2017 Background Bioconversion of d-galacturonic acid to galactaric (mucic) acid has previously been carried out in small scale (50–1000 mL) cultures, which produce tens of grams of galactaric acid.

Engineering Aspergillus niger for galactaric acid production: elimination of galactaric acid catabolism by using RNA sequencing and CRISPR/Cas9. [PDF]
Microb Cell Fact, 2016 meso-Galactaric acid is a dicarboxylic acid that can be produced by the oxidation of D-galacturonic acid, the main constituent of pectin. Mould strains can be engineered to perform this oxidation by expressing the bacterial enzyme uronate dehydrogenase. In addition, the endogenous pathway for D-galacturonic acid catabolism has to be inactivated.

Synthesis of N-Substituted Pyrrole-2,5-Dicarboxylic Acids from d-Galactaric Acid. [PDF]
ChemSusChemPyrrole‐2,5‐dicarboxylic acid (PDCA) and its N‐substituted derivatives are interesting building blocks for macromolecular applications. However, only a few published procedures describe the synthesis of PDCA derivatives. These procedures often suffer from low yields, the formation of unwanted side products, harsh reaction conditions, the use of toxic ...

The ultrastiff crystals of mucic (galactaric) acid. [PDF]
Chem SciWe show that mucic (galactaric) acid crystals are exceptionally stiff, with a nanoindentation Young’s modulus of 50.25 ± 1.55 GPa and hardness of 2.81 ± 0.15 GPa—values exceeding those of other very stiff organic crystals such as α-glycine, tartaric acid, and l -threonine.
