Autor: W. A. Bazaraa, Nagwa M. El-Shimi, Reda Mahgoub Mohamed, A. M. Alian

Publikováno v: Biocatalysis and Agricultural Biotechnology. 6:76-81

The glutaminase produced from Aspergillus oryzae NRRL 32567 was purified (10.2 folds) using ammonium sulfate fractionation followed by gel filtration on Sephadex G-75. SDS-PAGE of the purified glutaminase showed the presence of one band with a molecu

Autor: Nagwa M. El Shimi, W. A. Bazaraa, Reda Mahgoub Mohamed, A. M. Alian

Publikováno v: African Journal of Microbiology Research. 9:588-597

Various fungal strains have been screened for L- glutaminase synthesis. Aspergillus oryzae NRRL 32657 proved to be the highest producer (24.19 U.ml-1) with the largest pink zone diameter (8 mm). Production of L- glutaminase (E.C. 3.5.1.2. L-glutamine

EFFECTS OF CU, MN, PB AND CD ON THE TECHNOLOGICAL PROPERTIES OF BAKER'S YEAST (IN VITRO STUDY)

Autor: Nagwa M. El-Shimi, G. N. Abdel-Rhaman, A. M. Ihab, M. M. Saad

Publikováno v: Journal of Food and Dairy Sciences. 34:8891-8901

Effect of different concentrations of heavy metals (Cu, Mn, Pb and Cd) on four parameters of baker's yeast (yield, total viable cells, protein content and fermentation power) representing their technological properties were tested. Increasing the con

OPTIMIZATION OF FERMENTATION MEDIUM FOR α-AMYLASE PRODUCTION BY FREE AND IMMOBILIZED Aspergillus niger ON PALM TREE FIBERS

Autor: Reda M. Abou Al-Alla, W. A. Bazaraa, Nagwa M. El-Shimi

Publikováno v: Journal of Agricultural Chemistry and Biotechnology. 32:6753-6768

Various strains of Aspergillus niger were screened for α- amylase synthesis. Strain 3 proved to be the highest producer (1.82 U. ml-1). Production of α- amylase by Aspergillus niger 3 in batch shaking system was optimized. The highest α- amylase p
