Enhanced Solubilization of Iron and Calcium phosphates by Aspergillus niger by the Addition of Alcohols
The present study deals with the effect of increased concentrations of alcohols (methanol and ethanol) on the solubilization of FePO4 and CaHPO4 by Aspergillus niger. The efficiency of solubilization (ES) of inorganic phosphates, fungal growth, acid production and pH variation were determined. The concentrations of alcohols that most favored the solubilization of phosphates were 4% methanol and...
متن کاملGlycosidases of Aspergillus niger
A highly purified preparation of 1,2-oc-L-fucosidase, free of /3-galactosidase and P-N-acetylglucosaminidase activities, has been obtained from a commercial preparation of Aspergillus niger by a simple isolation procedure involving ammonium sulfate precipitation, pressure dialysis, repeated gel Cltration on Sephadex G-150, and chromatography on diethylaminoethyl Sephadex A-50. The enzyme has a ...
متن کاملBiosorption of Pentachlorophenol from Aqueous Solutions by Aspergillus Niger Biomass
Background: This study aimed to investigate the biosorption of pentachlorophenol on Aspergillus niger biomass as a method for removal of pentachlorophenol from aqueous solutions. Methods: Modified A. niger biomass with NaOH was used to absorb the pentachlorophenol. The impacts of various experimental parameters like primary pentachlorophenol concentration, pH of the solution, contact time, a...
متن کاملRetting of Flax by Aspergillus niger.
In this study, retting was carried out by Aspergillus niger. The pH, galacturonic acid (GA), and total reducing sugar were determined; the end point was identified by the classic empirical processes and by the maximal GA content of the retting water. The process gave clear and resistent fibers, and the retting time was similar to that of current industrial processes with bacterial enzymes. Cont...
متن کاملLysine aminopeptidase of Aspergillus niger.
Conserved regions within the M1 family of metallo-aminopeptidases have been used to clone a zinc aminopeptidase from the industrially used fungus Aspergillus niger. The derived amino acid sequence of ApsA is highly similar to two yeast zinc aminopeptidases, LAPI and AAPI (53.3 and 50.9% overall similarity, respectively), two members of the M1 family of metallo-aminopeptidases. The encoding gene...
