Commercial Yeast Strains Expressing Polygalacturonase and Glucanase Unravel the Cell Walls of Chardonnay Grape Pomace

Biology, 2022
Industrial wine yeast strains expressing hydrolytic enzymes were fermented on Chardonnay pomace and were shown to unravel the cell walls of the berry tissues according to the enzyme activities.

Regulation of endo-polygalacturonase activity inSaccharomyces cerevisiae [PDF]

FEMS Yeast Research, 2010
Pectolytic activity in Saccharomyces cerevisiae is due to the secretion of an endo-polygalacturonase encoded by the PGU1 gene. The ability to degrade polygalacturonic acid has been shown to vary between different strains. In this study, we attempted to elucidate how pectolytic activity is regulated in S. cerevisiae and to determine whether the means of

Chemical and nutritional characteristics, and microbial degradation of rapeseed meal recalcitrant carbohydrates: A review

Frontiers in Nutrition, 2022
Approximately 35% of rapeseed meal (RSM) dry matter (DM) are carbohydrates, half of which are water-soluble carbohydrates. The cell wall of rapeseed meal contains arabinan, galactomannan, homogalacturonan, rhamnogalacturonan I, type II arabinogalactan ...

Separation of endo-polygalacturonase using aqueous two-phase partitioning [PDF]

Journal of Chromatography A, 2001
The partitioning of endo-polygalacturonase (endo-PG) in polyethylene glycol (PEG)-polyvinyl alcohol (PVA10000) and PEG-hydroxypropyl starch (Reppal PES100) aqueous two-phase systems was studied, and revealed the possibility of using aqueous two-phase extraction to purify and concentrate endo-PG from its clarified fermentation broth.

Cold shock treatment extends shelf life of naturally ripened or ethylene-ripened avocado fruits. [PDF]

PLoS ONE, 2017
Avocado is an important tropical fruit with high commercial value, but has a relatively short storage life. In this study, the effects of cold shock treatment (CST) on shelf life of naturally ripened and ethylene-ripened avocado fruits were investigated.

Metabolic engineering of Bacillus subtilis with an endopolygalacturonase gene isolated from Pectobacterium. carotovorum; a plant pathogenic bacterial strain.

PLoS ONE, 2021
Pectinolytic enzymes or pectinases are synthesized naturally by numerous microbes and plants. These enzymes degrade various kinds of pectin which exist as the major component of the cell wall in plants.

Polygalacturonase and xylanase forms produced by Fusarium avenaceum in infected lupin roots and their sensitivity to a cell wall glycoprotein

Acta Agrobotanica, 2013
Using CM-Sepharose column chromatography it was shown that Fusarium avenaceum produced two forms of endo-polygalacturonase, one exo-polygalacturonase and two forms of endo-xylanase in infected Iupin roots.

Relationships Among Endo-Polygalacturonase, Oxalate, pH, and Plant Polygalacturonase-Inhibiting Protein (PGIP) in the Interaction Between Sclerotinia sclerotiorum and Soybean

Molecular Plant-Microbe Interactions, 2004
The necrotrophic fungal pathogen Sclerotinia sclerotiorum secretes oxalic acid and endo-polygalacturonase (endo-PG) in host plants. Oxalic acid acidifies the plant tissue to values more suitable to endo-PG activity. However, we observed that the infected

Enzymatic preparation of fructooligosaccharides-rich burdock syrup with enhanced antioxidative properties

Electronic Journal of Biotechnology, 2019
Background: Burdock (Arctium lappa L.) is a fructan-rich plant with prebiotic potential. The aim of this study was to develop an efficient enzymatic route to prepare fructooligosaccharides (FOS)-rich and highly antioxidative syrup using burdock root as a
