Pectinase 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 کاملPurification and characterization of polygalacturonase from Aspergillus fumigatus MTCC 2584 and elucidating its application in retting of Crotalaria juncea fiber
Polygalacturonases represents an important member of pectinases group of enzymes with diverse industrial applications and is widely distributed among fungi, bacteria, yeasts, plants and some plant parasitic nematodes. An endo-polygalacturonase from a new fungal source Aspergillus fumigatus MTCC 2584 was produced under solid-state fermentation conditions and was purified simply by acetone precip...
متن کاملAspergillus fumigatus in Poultry
Aspergillus fumigatus remains a major respiratory pathogen in birds. In poultry, infection by A. fumigatus may induce significant economic losses particularly in turkey production. A. fumigatus develops and sporulates easily in poor quality bedding or contaminated feedstuffs in indoor farm environments. Inadequate ventilation and dusty conditions increase the risk of bird exposure to aerosolize...
متن کاملGlycosylinositolphosphoceramides in Aspergillus fumigatus.
Fungal glycosylinositolphosphoceramides (GIPCs) are involved in cell growth and fungal-host interactions. In this study, six GIPCs from the mycelium of the human pathogen Aspergillus fumigatus were purified and characterized using Q-TOF mass spectrometry and 1H, 13C, and 31P NMR. All structures have the same inositolphosphoceramide moiety with the presence of a C(18:0)-phytosphingosine conjugat...
متن کاملStudies on an alkali-thermostable xylanase from Aspergillus fumigatus MA28
An alkalitolerant fungus, Aspergillus fumigatus strain MA28 produced significant amounts of cellulase-free xylanase when grown on a variety of agro-wastes. Wheat bran as the sole carbon source supported higher xylanase production (8,450 U/L) than xylan (7,500 U/L). Soybean meal was observed to be the best nitrogen source for xylanase production (9,000 U/L). Optimum medium pH for xylanase produc...
