Isolation and Characterization of Polygalacturonase Produced by Tetracoccosporium sp.
Thirty-five fungal strains which isolated from vegetable wastes, were screened for the use of polygalacturonic acid as the sole carbon source. Twenty-five isolates were positive for polygalacturonase activity in cup-plate assay, as evidenced by clear hydrolysation zones. The most productive strain was determined by measuring clear zones formed around colonies stained with ruthenium red.</em...
متن کاملPolygalacturonase Production by Aspergillus sp. in Air-Lift and Agitated Fermentor
Polygalacturonase production under different shear stress environments by Aspergillus sp. was studied. It was found that the rate of enzyme production in the stirred tank fermentor decreased with increasing the stirrer speed in the range 300-750 rpm. On the other hand, in a split cylinder air-lift fermentor, the rate of polygalacturonase production slightly increased with increasing in air ...
متن کاملOptimization of cellulase production by Penicillium sp.
The production of cellulolytic enzymes (β-exoglucanase, β-endoglucanase and β-glucosidase) by Penicillium sp. on three different media in liquid shake culture conditions was compared. The organism exhibited relatively highest activity of endoglucanase among three enzymes measured at 7-day interval during the course of its growth on Czapek-Dox medium supplemented with 0.5 % (w/v) cellulose. Cell...

متن کاملPolygalacturonase Production by Sclerotinia Sclerotiorum, Causal Agent of Canola Stem Rot: Parameter Optimization Using Taguchi Approach
Submerged culture conditions for polygalacturonase production by Sclerotinia sclerotiorum (MR5) were optimized by Taguchi orthogonal array experimental design methodology. This approach facilitates the study of interaction of a large number of variables spanned by factors and their settings with a small number of experiments leading to considerable saving in time and cost for the process optimi...
