Plant Polygalacturonases Involved in Cell Elongation and Separation—The Same but Different?

Plants, 2014
Plant cells are surrounded by the primary cell wall, a rigid framework that needs to be modified in order to allow cell growth. Recent data suggest that in addition to the cellulose-hemicellulose network, the pectin matrix plays a critical role in ...

Polygalacturonase activity in starfruit

, 1987
Polygalacturonase (PGase) was extracted and partially purified from ripe starfruit (Averrhoa carambola, L.). 2·3- and 7·8-fold purifications were obtained following purification by Amicon ultrafiltration and Sephadex G-100 filtration, respectively.

Polygalacturonase is the key component in enzymatic retting of flax

, 2000
Seven commercial enzyme mixtures were tested for their ability to perform retting of flax (i.e. to separate flax fibers by partly removal of middle lamella) and were assayed for hydrolysis of xylan, cellulose and four kinds of pectin.

Optimization, Purification and Characterization of Polygalacturonase from Mango Peel Waste Produced by Aspergillus foetidus

Food Technology and Biotechnology, 2014
Pectin-rich mango peel from industrial waste was used as a substrate for the production and characterization of novel polygalactauronase enzyme. Its production was optimized with five important factors; KH2PO4, pH, peptone, MgSO4 and urea by employing ...

Microstructural and Enzymatic Contributions to Texture in High Pressure Processed Fruits and Vegetables

Foods
High pressure processing (HPP) is common for beverage treatment, but its application to whole fruits and vegetables is more complex given their susceptibility to tissue softening and noticeable texture changes.

The enhancement of polygalacturonase and polymethylgalacturonase production on solid-state conditions by Aspergillus foetidus

, 2008
In this study, a previously isolated strain of Aspergillus foetidus Ege-K-635 producing highly active polygalacturonase and polymethylgalacturonase was used for improvement of enzyme production using solid-state conditions.
