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 ...

Simulation of force spectroscopy experiments on galacturonic acid oligomers. [PDF]
PLoS ONE, 2014 Pectins, forming a matrix for cellulose and hemicellulose, determine the mechanics of plant cell walls. They undergo salient structural changes during their development.

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 ...

Online evaluation of the metabolic activity of Ustilago maydis on (poly)galacturonic acid [PDF]
Journal of Biological Engineering, 2018 Background Pectin is a rather complex and highly branched polysaccharide strengthening the plant cell wall. Thus, many different pectinases are required for an efficient microbial conversion of biomass waste streams with a high pectin content like citrus

Copper ions-coordinated galacturonic acid-modified UiO-66-NH2 as a nanocatalyst for the eco-friendly synthesis of pyrroles and polyhydroquinolines [PDF]
Scientific ReportsIn this study, a novel metal-organic framework (MOF) nanocatalyst was prepared by modifying UiO-66-NH2 with galacturonic acid (UiO-Galacturonic). Then, copper ions were coordinated to the galacturonic acid ligands on the surface of UiO-66-NH2, yielding a

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.

Towards By-Product Utilisation of Pea Hulls: Isolation and Quantification of Galacturonic Acid [PDF]
Foods, 2018 In order to evaluate by-products from food processing as alternative raw materials for pectin extraction, their amount of galacturonic acid (GalA) has to be analysed as a marker for pectin content.

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 ...

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.

Optimize the Extraction Conditions of Pectin Extracted from Saveh Pomegranate Peels [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2022 In recent years, numerous studies have been done on the beneficial use of food waste. Pomegranate is widely used in food industries, and the skin of this fruit containing the valuable substance, pectin, is discarded as waste.
