Engineering marine fungi for conversion of d-galacturonic acid to mucic acid [PDF]
Microbial Cell Factories, 2020 Background Two marine fungi, a Trichoderma sp. and a Coniochaeta sp., which can grow on d-galacturonic acid and pectin, were selected as hosts to engineer for mucic acid production, assessing the suitability of marine fungi for production of platform ...

Genomewide and Enzymatic Analysis Reveals Efficient
mSystems, 2019 Biorefining of renewable feedstocks is one of the most promising routes to replace fossil-based products. Since many common fermentation hosts, such as Saccharomyces cerevisiae, are naturally unable to convert many component plant cell wall ...

The introduction of the fungal D-galacturonate pathway enables the consumption of D-galacturonic acid by Saccharomyces cerevisiae. [PDF]
Microb Cell Fact, 2016 Pectin-rich wastes, such as citrus pulp and sugar beet pulp, are produced in considerable amounts by the juice and sugar industry and could be used as raw materials for biorefineries. One possible process in such biorefineries is the hydrolysis of these wastes and the subsequent production of ethanol.

W361R mutation in GaaR, the regulator of D‐galacturonic acid‐responsive genes, leads to constitutive production of pectinases in Aspergillus niger [PDF]
MicrobiologyOpen, 2019 Polysaccharides present in plant biomass, such as pectin, are the main carbon source for filamentous fungi. Aspergillus niger naturally secretes pectinases to degrade pectin and utilize the released monomers, mainly D‐galacturonic acid.

Engineering Saccharomyces cerevisiae for co-utilization of d-galacturonic acid and d-glucose from citrus peel waste [PDF]
Nature Communications, 2018 Pectin-rich agricultural byproducts are ideal feedstocks for biobased chemicals production. Here, the authors engineer the yeast, S. cerevisiae, in several steps to co-utilize d-galacturonic acid and d-glucose and demonstrate the potential of producing ...

Regioselective Oxidation of D-Galacturonic Acid to Provide Crystallized Mucic Acid Using Engineered Gluconobacter oxydans [PDF]
BioTechMucic acid (MA) is used as a chelating agent or as a building block for bio-based polymers. MA can be produced by regioselective oxidation of D-galacturonic acid (GA).

Physicochemical Properties, Structural Characterization and Protective Effect on Erythrocyte Oxidative Damage of Selenized Lonicera caerulea L. Polysaccharide [PDF]
Shipin Kexue, 2023 Selenized Lonicera caerulea L. polysaccharide was obtained by microwave-assisted HNO3-Na2SeO3 method and purified by column chromatography. The selenium content of the selenized polysaccharide was (0.184 ± 0.03) mg/g with an average molecular mass of 58 ...
