Application of tailormade pectinases
1996Abstract Heterologous expression of pectinolytic enzymes has made it possible to tailormake pectinolytic enzyme preparations. Composition of pectinase products for existing applications can be improved, and products for new applications can be made.

In debarking the bark is removed from wood along the cambial layer. Pretreatment with pectinases improves the efficiency of mechanical debarking measured as reduction of energy consumption in a laboratory scale debarker. The effects of different pectinases vary significantly depending on the side activities of the enzyme preparations The main ...

Pectinases of Thermophilic Microbes
2013Represented by archeal, bacterial, and fungal species, thermophilic organisms have been isolated from all types of terrestrial and marine hot environment. Pectinase from these organisms (thermophilic pectinase) developed unique structure–function properties of high thermostability and optimal activity at higher temperature.

Sequential production of pectinases byPenicillium frequentans
World Journal of Microbiology & Biotechnology, 1995The pectinases produced byPenicillium frequentans were subjected to pectin- or sodium polypectate-PAGE. The fungus secreted one endo- and one exo-polygalacturonase during the first 10 h of incubation, either in media supplemented with pectin or in the absence of carbohydrate source.

BACKGROUND Lignocellulosic wastes are pretreated prior to their utilization in fermentation processes. Since pretreatment also alters the topological features of the substrates, therefore, the suitability of pretreated waste as immobilization matrix for ...

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 ...
