Screening of Aspergillus strains isolated from vineyards for pectinase production
by: shinta, 3 pagesPectin is present in walls of plant cells. Pectinases are important for food and chemical industry that processes plant material, and also juice, textile and vine industry uses pectinases. They ...
In vivo pectin solubility in ripening and chill-injured tomato fruit
by: shinta, 9 pagesIn vivo pectin solubility was examined in ripening and chill-injured tomato fruit with down-regulated polygalacturonase (PG, EC 3.2.1.15) activity and untransformed wild-type fruit by analyzing ...
Polygalacturonase isozymes produced during infection of the grape berry by Botrytis cinerea
by: shinta, 4 pagesThis paper focuses on polygalacturonase activity dur- ing the early stages of infection of the grape berry by the fungus Botrytis cinerea. While a weak polygalacturonase activity ...
Partial Purification of Polygalacturonase from Tomato Fruits Infected by Rhizopus arrhizus Fisher
by: shinta, 6 pagesThe production of polygalacturonase during the deterioration of tomato (Lycopersicon esculentum Mill.) by Rhizopus arrhizus Fisher was investigated. The enzyme was partially purified by ...
Enzymatic Hydrolysis of Pectic Acid and Pectins by Polygalacturonase from Aspergillus niger
by: shinta, 6 pagesA study was carried out on the degree of methylation influence on enzymatic hydrolysis (polygalacturonase) on pectic acid and different pectins. The action of polygalacturonase was ...
Hydrolysis of pectin : An enzymatic approach and its application in banana fiber processing
by: shinta, 7 pagesSediment samples were collected from different estuarine and marine areas along the West coast of India. Eighteen actinomycete cultures were isolated using starch casein agar and were ...
Induction of polygalacturonase and the formation of oxalic acid by pectin in brown
by: shinta, 6 pagesExtracellular polygalacturonase (PG) production was estimated in vitro, using liquid cultures of three species of brown-rot decay fungi (Postia placenta, Gloeophyllum trabeum and Serpula ...
A DIVERGENT POLYGALACTURONASE OF FUSARIUM PHYLLOPHILUM SHOWS SEQUENCE AND FUNCTIONAL SIMILARITY TO THE ENZYME OF F. VERTICILLIOIDES
by: shinta, 12 pagesEndopolygalacturonases (endoPGs) are fungal en- zymes secreted during the infection in order to degrade plant cell wall pectins. In Fusarium spp., endoPGs are among the first ...
High-level expression of apple PGIP1 is not sufficient to protect transgenic potato against Verticillium dahliae
by: shinta, 11 pagesPolygalacturonase-inhibiting proteins (PGIPs) are plant proteins believed to play a role in the defence against pathogenic fungi. Purified apple PGIP1 inhibited polygalacturonases (PGs) ...
