Pectin: New insights from an old polymer through pectinase-based genetic screens
… Those were obtained by a recently developed pectinase-based genetic screen. Arabidopsis thaliana seedlings grown in liquid medium containing pectinase solutions exhibited particular phenotypes: they were dwarfed and slightly chlorotic. However, when genetically different A. thaliana seed …

RAMIE (BOEHMERIA NIVEA): AN UNDERUTILIZED PLANT FOR A MULTIPURPOSE INDUSTRIAL APPLICATION; A PERENNIAL PLANT WITH PROTEIN IDENTIFICATION USING MALDI-MS, A BIOSORBENT FOR Hg (II) REMOVAL FROM WATER AND AS A BAST FIBER PRODUCTION VIA ENZYMATIC DEGUMMING
… focuses on using a combined degumming method of pectinase enzyme and a 5 % Na<sub>2</sub>CO<sub>3</sub> for the treatment of ramie fibers. The treatment method revealed good individual fibers with a clean surface and the removal of the gummy materials on the fiber surface as compared to methods …

Strategies for Increasing the Release of Pigments in Red Wine
… (3%) during barrel aging were observed. Adding pectinase-rich macerating enzymes increased the total phenols by 8.7 and 21.0% to the 2010 and 2011 vintage, respectively, and tannin concentrations by 20.8 and 48.8%, respectively, during barrel aging. Alcoholic fermentation temperature of 25.0°C …

Application of molecular markers to characterize potato plants derived from anther culture and protoplast fusion
… of which have been digested by a combination of pectinase and cellulase enzymes. If the protoplasts are cultured in a suitable medium, they can resynthesize the cell walls, divide and regenerate complete plantlets. But if a successful fusion of protoplasts from sexually incompatible parents is …

Cellulase and related enzyme activity in protoplasts and mycelium of filamentous fungi.
Production of cellulase, pectinase and xylanase was investigated using culture filtrates from selected mesophilic (Aspergillus niger, Penicillium funiculosum, Penicillium janthinellum, Penicillium ochrochloron, Trichoderma viride), thermotolerant (Aspergillus fumigatus) and thermophilic (Geosmithia …

Biology of Fungi on Plants in the Sub-Antarctic
… oxidation and all showed protease activity. Pectinase activity was exhibited by all of the phylloplane species tested. Only Botrytis cinerea appeared to be capable of lignin degradation. Significant cellulase activity continued at 1°C, with an optimum around 20°C. Studies on the effects of …

Enzimi, acidi organici ed altri metaboliti coinvolti nella patogenesi di Penicillium spp
… gave a positive reaction to esterase, urease, pectinase activity, in addition, the pathogen is able to synthesize a complex enzyme act to degrade the main components of the cell wall especially pectin and cellulose. Isolated sensitive and resistant are characterized by a good activity of …

Wastewater treatment alternatives for a vegetable and seafood cannery
… an enzyme peeling study was performed using pectinase. Peeling ability of the enzyme was not as good as that of caustic, however, further investigation into alternative peeling operations is warranted due to the adverse effects of caustic materials on wastewater treatment alternatives.

Plant Activation of Bicyclic Aromatic Amines, Benzidine and 4-Aminobiphenyl
… plant-activated benzidine after treatment with pectinase was a potent genotoxin in mammalian cells. These data suggest that plant-activated xenobiotics may be converted into stable forms, perhaps in the pectin component in the plant cell wall. This plant activation may be a process to transport …
