A pectolytic enzyme preparation from Aspergillus niger (pectinase AN) decreased most rutin content and antioxidant activity of asparagus juice. To investigate the mechanism of such loss, we analyzed several possible related enzyme activities in pectinase AN. We found that the activity of pectinase AN to oxidize guaiacol had no significant difference with or without the presence of H2O2; thus it...

The dried mango fruit processing industrial waste (MIW) used as carbon source for the production of pectinase from fungal strains. Eight fungal strains were isolated from MIW and screened for their ability to produce pectinase by pectin clear zone (PCZ) technique. Fusarium sp. (PSTF1) showed highest PCZ value of 52 mm. The physico-chemical characteristics of the medium were standardized for hig...

in this research, the effect of different concentrations of pectinase has been investigated on deinking of old newspaper (onp). onp re-pulped at 5% consistency for 10 min in disintegrator (with 2650 rpm). enzymatic treatment of recycled onp pulp was done under constant conditions (10% consistency, duration time of 20 min, ph range of 4.5-5) at different pectinase concentrations (0.05, 0.1, 0.2,...

A pectinase producing fungus was isolated from compost soil. Morphological characteristics, microscopic observations and molecular characterization based on internal transcribed spacer (ITS) sequences led to its identification as Aspergillus niger (GenBank Accession Number: JX556221) and it was designated as Aspergillus niger strain K3. In the present study, the culture condition of the media w...

In the present study, media composition for high production of pectinase by Enterobacter sp. PSTB-1 in submerged fermentation was optimized using response surface methodology (RSM). Mango fruit processing industrial waste (MIW) was used as substrate (carbon source) as it contains high amount of pectin. Enterobacter sp. PSTB-1 used in present study has given pectin clear zone (PCZ) of 34 mm is h...

Pectinases have multiple nature and various forms which are necessary for the hydrolysis of pectin in several conventional industrial and natural processes. In this investigation fourteen fungal strains which isolated from agricultural soils ,were screened for pectinase activity. Pectinase activity were measured in vitro by assaying released reducing sugar from pectin as sole carbon source. Asp...

In this study, Aspergillus terreus NCFT4269.10 was selected for the biosynthesis of pectinase after screening from fifteen native fungal strains as the performance of A. terreus was best in pectin hydrolyzing activity (2.75 cm). Aiming at the cost effective fermentation, several agro-industrial residues such as, Pearl Millet (PM), Finger Millet (FM), Orange Peels (OP), Mustard oil Cake (MoC) an...

Fusarium oxysporum strain BM-201 was treated with ultraviolet (UV) radiation to obtain a high pectinase-producing strain. Mutant UV-10-41 was obtained and then treated by diethyl sulfate. Next, the mutant UV-diethyl sulfate-43 derived from UV-10-41 was selected as high pectinase-producing strain. Mutant UV-diethyl sulfate-43 was incubated on slant for 10 generations, demonstrating that the pect...

Genes acquired by horizontal transfer are increasingly being found in animal genomes. Understanding their origin and evolution requires knowledge about the phylogenetic relationships from both source and recipient organisms. We used RNASeq data and respective assembled transcript libraries to trace the evolutionary history of polygalacturonase (pectinase) genes in stick insects (Phasmatodea). B...
