A continuous clarification of grape juice was undertaken in a packed bed reactor (PBR) using pectinase enzymes immobilized on glass beads. The enzyme immobilization process decreased the specific activity and the volumetric productivity from 3 ± 0.2 to 2.

Environmentally benign Scouring of Cotton Knits Using Locally Produced Acid Pectinase Enzyme
Fibers and Polymers, 2019The main task of the present study is to pre-screen selected fungal strain (Fusarium oxysporum M1-EGY) isolated from local agriculture soil and optimize cultivation conditions for an acid pectinase production. Experimental results demonstrated the optimum conditions for achieving the highest enzyme activity (14.80 U/ml) were found to be: incubation ...

Bioscouring of cotton with pectinase enzyme
Journal of the Society of Dyers and Colourists, 1998We have studied bioscouring of cotton using pectinase enzyme, together with multiple mixed surfactants and D‐limonene as scouring assistants. The effectiveness of the bioscouring was evaluated by means of wetness testing, weight‐loss measurement of cotton substrate and analyses of the amounts of pectic substance and cotton wax remaining in the ...

Quality of soursop juice after pectinase enzyme treatment
Food Chemistry, 1994Abstract A pectinase enzyme was used at 0-0.1% concentrations to help in the extraction of soursop juice. The incubation times were from 1–3 h. The juices obtained were evaluated for yield, titratable acidity, pH, ascorbic acid, total soluble solids, viscosity, turbidity and sugar contents.

Hydrolysis of grapefruit peel waste with cellulase and pectinase enzymes
Bioresource Technology, 2007Approximately 1 million metric tons of grapefruit were processed in the 2003/04 season resulting in 500,000 metric tons of peel waste. Grapefruit peel waste is usually dried, pelletized, and sold as a low-value cattle feed. This study tested different loadings of commercial cellulase and pectinase enzymes and pH levels to hydrolyze grapefruit peel ...

Hydrolysis of orange peel with pectinase and cellulase enzymes
Biotechnology Letters, 1992Hydrolysis of polysaccharides in comminuted orange peel by commercial cellulase and pectinase enzymes has been investigated. High levels of conversion to monomeric sugars were observed after treatment with pectinase enzyme, but cellulase enzyme achieved only limited solubilization. The combination of cellulase and pectinase enzymes appears to be a most

Food and Bioproducts Processing, 2012 A comparative evaluation of three Aspergillus species according to their pectinase production in solid-state fermentation was performed. Solid-state fermentation offers several potential advantages for enzyme production by fungal strains. Utilization of agricultural by-products as low-cost substrates for microbial enzyme production resulted in an ...

Green Enzymes from Fruit Waste Aspergillus Sp-Derived Pectinase
Journal of Scientific ResearchPectinase is one of the essential enzymes used in industry and biotechnology, along with cellulase and amylase. This study aimed to isolate pectinase-enzyme-producing organisms and characterise them. Fungal cultures with pectinase activity were isolated from different samples of rotten fruits like oranges, bananas, pomegranates, and soil samples.

Bioscouring of cotton with pectinase enzyme in a non‐aqueous system
Journal of the Society of Dyers and Colourists, 1998We have studied bioscouring of cotton using pectinase enzyme in a reverse micellar system. The effectiveness of the bioscouring was evaluated by measuring the weight loss of cotton substrate, analysing the pectin and cotton wax remaining and by wetness testing.

Pectinase and Cellulase Enzyme Inhibitor from Sericea and Certain Other Plants
Botanical Gazette, 1965A water-soluble substance isolated from the leaves of seven plant species is shown to inhibit the fungal hydrolytic enzymes, pectinase and cellulase. Three plants-sericea, muscadine grape, and persimmon-were found to be good sources of the inhibitor. Preparations of all three, isolated by the caffeine-complex method, were rated about equal in enzyme ...
