Safety evaluation of the food enzyme pectin lyase from the genetically modified Aspergillus niger strain CCTCC M 2023341

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The food enzyme pectin lyase (1,4‐6‐O‐methyl‐α‐d‐galacturonan lyase, EC 4.2.2.10) is produced with the genetically modified Aspergillus niger strain CCTCC M 2023341 by Suntaq International Limited. The genetic modifications do not give rise to safety concerns. The food enzyme was considered free from viable cells of the production organism and

Polygalacturonase Production by Aspergillus sp. in Air-Lift and Agitated Fermentor [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2009
Polygalacturonase production under different shear stress environments by Aspergillus sp. was studied. It was found that the rate of enzyme production in the stirred tank fermentor decreased with increasing the stirrer speed in the range 300-750 rpm.

Regulation of the production of polygalacturonase byAspergillus niger

Folia Microbiologica, 2002
Synthesis of ethylene in static cultures as well as the effect of endogenous and exogenous ethylene on the synthesis of polygalacturonase by Aspergillus niger were determined. This strain produced maximum ethylene amounts when cultured at 30 degrees C for 3 d. The effect of adding ethylene precursors (citrate-cycle intermediates) on ethylene production

Edible Antifungal Coatings Based on Litchi Chinensis Seed Starch Enriched With Pericarp Procyanidins for the Postharvest Preservation of Strawberries

Food Chemistry International, Volume 2, Issue 2, Page 200-210, June 2026.
Lychee starch coatings enriched with procyanidins showed strong antifungal activity and effectively preserved strawberry quality postharvest, reducing weight loss, decay, and senescence. This highlights their potential as a sustainable natural alternative for shelf‐life extension and fungal control in fresh produce.

Plants use identical inhibitors to protect their cell wall pectin against microbes and insects

Ecology and Evolution, 2020
As fundamentally different as phytopathogenic microbes and herbivorous insects are, they enjoy plant‐based diets. Hence, they encounter similar challenges to acquire nutrients. Both microbes and beetles possess polygalacturonases (PGs) that hydrolyze the

Genome-Wide Identification and Expression Analysis of Polygalacturonase Gene Family in Kiwifruit (Actinidia chinensis) during Fruit Softening

Plants, 2020
Polygalacturonase (PG) is an essential hydrolytic enzyme responsible for pectin degradation and thus plays an important role in fruit softening and other cell separation processes.

A Profusion of Molecular Scissors for Pectins: Classification, Expression, and Functions of Plant Polygalacturonases

Frontiers in Plant Science, 2018
In plants, the construction, differentiation, maturation, and degradation of the cell wall are essential for development. Pectins, which are major constituents of primary cell walls in eudicots, function in multiple developmental processes through their ...

Polygalacturonase from Sitophilus oryzae: Possible horizontal transfer of a pectinase gene from fungi to weevils

Journal of Insect Science, 2003
Endo-polygalacturonase, one of the group of enzymes known collectively as pectinases, is widely distributed in bacteria, plants and fungi. The enzyme has also been found in several weevil species and a few other insects, such as aphids, but not in ...
