Immobilization of pectinase fromSclerotium rolfsii
Folia Microbiologica, 1995Immobilization of pectinase fromS. rolfsii was studied on different matrices of which Amberlite XAD-7 showed maximum adsorption and expression of the enzyme. The most active preparation was obtained when XAD-7 was activated with 2% glutaraldehyde and 1.7 μkat of enzyme per g resin was used for immobilization at pH 5.5 and 28°C.

Pectinases are a group of enzymes which hydrolyze pectin, one of the main polysaccharides in plant cell wall. These are distributed in many higher plants and microorganisms. Pectinases play a very important role in plants since they help in cell-wall extension and softening of some plant tissues.

Pectinases in Ditylenchus Dipsaci
Nematologica, 1967Extracts of Ditylenchus dipsaci were most active in decreasing the viscosity of solutions of pectin N.F., less active towards pectin L.M., and least active towards Na polypectate. Optimum pH for activity of extracts was 6.0 for pectin N.F. and pectin L.M., and 5.0 for Na polypectate.

Cellulases, Hemicellulases, and Pectinases
2014The study of cellulases is important from the standpoint of microbial conversion of biomass to feeds and chemical feed stock. The complex structure of hemicelluloses has dictated a correspondingly diverse array of hemicellulases. The concentration (or actually dilution) of enzyme preparation required to effect this level of depolymerization is ...

Resuable Pectinase Nano Polymeric Particles
Journal of Proteomics & Enzymology, 2014Pectinase or pectinolytic enzymes are the group of enzymes that degrade the pectin substances.They have great importance in food industry especially for the production of clear fruit juice. In this study, a new method has been developed for hydrolysis of pectin by using nano pectinase particles in hydrolysis of pectin.

Pectinase Inhibitor in Grape Leaves
Botanical Gazette, 19581. A water-soluble substance in grape leaves which inhibits both purified polygalacturonase (PG) and pectinase from mold-laden cucumber flowers is reported. 2. Of the six grape varieties tested, the leaves from the Scuppernong variety of the Muscadine group (Vitus rotundifolia Michx.) contained the highest inhibitor content. 3. The inhibiting substance

Pectinase Technique for Isolating Plant Cells
Nature, 1952PLANT root meristems are a readily available source of mitotic cells which are ideal for cytological examination on account of their large size, high mitotic index and, in selected cases, small number of fairly large chromosomes. The root tip, in which the meristem is found, can be easily handled for experimental studies such as those on the uptake and

Turbidimetric Assay for Pectinase Activity
Israel Journal of Chemistry, 1967AbstractA simple procedure for the estimation of polygalacturonic acid and polymethyl‐galacturonic acid hydrolases is described. The method is based on measuring the residual turbidity formed by complexing the acid polysaccharide with quaternary‐ammonium detergents such as cetyl pyridinium bromide.

Application of pectinases in beverages
1996Abstract Pectinases are necessary processing aids in the production of clear and concentrated fruit juices. Improving pressing and clarification, they are biochemical tools of first importance. In combination with hemicellulases and cellulases, pectinases can lead to fruits liquefaction.
