Physiological and Molecular Plant Pathology, 1986
The water relations of Geotrichum candidum were characterized in an attempt to explain a previously reported relation [ Baudoin & Eckert (1982) , Phytopathology 72 , 1592–1597] between the water potential of lemon fruits and their susceptibility to decay caused by this fungus. G. candidum was grown in liquid nutrient media amended with solutes (K.

Strain and process for production of polygalacturonase
Enzyme and Microbial Technology, 1990A process was developed for the production of polygalacturonase (poly-1,4-α-d-galacturonide glycanohydrolase, EC 3.2.1.15) by Aspergillus niger VTT-D-77050 and its mutant VTT-D-86267. High levels of production were obtained in laboratory fermentations on a beet extraction waste medium.

Polygalacturonase from Corticium rolfsii
1988Publisher Summary Two assay methods have generally been employed for the estimation of polygalacturonase activity: release of reducing groups from pectic acid and viscosity reduction of pectic acid. The viscometric assay is more sensitive than the reducing group assay, so it is convenient for estimation of the minor activity.

Exo-polygalacturonase of apple
Phytochemistry, 1978Exo-polygalacturonase was extracted from apple cortical tissue. The enzyme hydrolyses polygalacturonic acid and has a pH optimum of 4.5–5 with this substrate. It is inhibited by EDTA and citrate and is activated by Ca2+ and to a lesser extent by Sr2+.

Applied biochemistry and biotechnology, 2004
The coproduction of ethanol and polygalacturonase (PG) in a pilot-scale batch fermentor using yeast extract--glucose (YD)--and sugar beet molasses (SBM)-based media was implemented utilizing a new high-PG-producing strain of Kluyveromyces marxianus. A certain growth inhibition was observed in SBM medium, causing ethanol and PG production to be lower ...

[Metabolism of Helix pomatia polygalacturonase].
Comptes rendus hebdomadaires des seances de l'Academie des sciences. Serie D: Sciences naturelles, 1976The reaction pattern of the polygalacturonase from Helix pomatia juice has been studied. Hydrolysis of pectic acid occurs in a random manner. Oligogalacturonic acids are hydrolyzed in a sequential process, starting from the non-reducing end. This behavior is different from that of other endopolygalacturonases, which split these latter substrates both ...
