Production of pectic enzymes in yeasts.
When grown in the appropriate medium, several yeast species produce pectinases able to degrade pectic substances. It is mainly exocellular endopolygalacturonases that break pectins or pectate down by hydrolysis of alpha-1,4-glycosidic linkages in a random way. Biochemical characterisation of these enzymes has shown that they have an optimal pH in the acidic region and an optimal temperature bet...
متن کاملPectic Enzymes
Indoleacetic acid (IAA) and/or inhibitors of DNA, RNA or protein synthesis were added to the apex of decapitated seedlings of Pisum sativum L. var. Alaska. At various times up to 4 days, enzymic protein was extraoted from a segment of epicotyl immediately below the apex and assayed for its ability to hydrolyse polysaccharides or their derivatives. With the exception of am;ylase, the total amoun...
متن کاملCellulase Enzymes Production from Pistachio Hull by Different Strains of Tichoderma Fungi
Six strain of Trichoderma (T. viride, T. harzianum, T. reesei, T. longibrachiatum, T. koningii, T. virens) were isolated and used for extracellular enzyme production. Species of Trichoderma are collected from the surrounding soil of suger beet root fields in East Iran, and held in vitro cultured PDA. TCM and TFM are used for the growth of spores and induceing the production of Cellulase. Finall...

متن کاملEffect of Rubber Petiole Cell Walls and Virulence of Strains on Secretion of Pectic Enzymes by Pytophthora Meadii
The characteristics of the pectic enzyme polygalacturonase (PG) of Phytophthora meadii isolates from petioles of rubber (Hevea brasiliensis) genotypes were compared in relation to (i) aggressiveness (virulence) in infecting detached petioles of a susceptible rubber genotype (PB86) or (ii) in relation to the availability of purified rubber petiole cell walls (obtained from a Phytophthora-resista...
