Production kinetics and characterization of pectinase enzyme from Aspergillus niger
Food grade pectinases from Aspergillus niger are predominantly used as processing aids in industries. In the present investigation, efforts towards standardization for pilot scale production of pectinase enzyme from A. niger were made. The crude enzyme was studied for its kinetics to optimize substrate concentration and processing parameters on the basis of polygalacturonic activity. Km (Michae...
متن کاملProduction of Feruloyl Esterase from Aspergillus niger by Solid-State Fermentation on Different Carbon Sources
A mixture of wheat bran with maize bran as a carbon source and addition of (NH(4))SO(4) as nitrogen source was found to significantly increase production of feruloyl esterase (FAE) enzyme compared with wheat bran as a sole carbon and nitrogen source. The optimal conditions in conical flasks were carbon source (30 g) to water 1 : 1, maize bran to wheat bran 1 : 2, (NH(4))SO(4) 1.2 g and MgSO(4) ...
متن کاملExploitation of Fruit Wastes for Pectinase Production Using Aspergillus Oryzae
Ever increasing population and industrialization has resulted in heavy pollution and waste generation. The main aim of this project lies in waste management and synthesis of pectinase enzyme which plays a crucial role in sewage treatment. Twenty moulds were isolated from decaying fruits and municipal waste soil sample on SDA and were further screened for pectinolytic enzyme production. Screenin...
متن کاملPectinase and Polygalacturonase Production by a Thermophilic Aspergillus Fumigatus Isolated from Decomposting Orange Peels
A thermophilic fungal strain producing both pectinase and polygalacturonase was isolated after primary screening of 120 different isolates. The fungus was identified as Aspergillus fumigatus Fres. MTCC 4163. Using solid-state cultivation, the optimum levels of variables for pectinase and polygalacturonase (PG) production were determined. Maximal levels of enzyme activities were achieved upon gr...
متن کاملISOLATION, PRODUCTION AND CHARACTERIZATION OF EXTRACELLULAR PECTINASE FROM Aspergillus niger K3
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...
