Enzymatic—spectrophotometric determination of phytic acid with phytase from Aspergillus ficuum

Analytica Chimica Acta, 1995
Abstract A method to determine phytic acid in the range 3–60 μM based on the spectrophotometric determination of inorganic phosphate with vanadate and molybdate, after liberation by enzymatic hydrolysis of phytic acid with phytase from Aspergillus ficuum at pH 2.5 and 37 °C is reported.

Crystal structure of phytase from Aspergillus ficuum at 2.5 Å resolution

Nature Structural Biology, 1997
Phytase is a high molecular weight acid phosphatase. The structure has an alpha/beta-domain similar to that of rat acid phosphatase and an alpha-domain with a new fold.

Effect of colour LEDs on mycelia growth of Aspergillus ficuum and phytase production in photo-fermentations

Journal of Photochemistry and Photobiology B: Biology, 2012
Aspergillus ficuum grown on plates and in liquid cultures were illuminated by a white fluorescent light and four different colour LED lights (white, blue, green and red) to evaluate the regulation of LED lights on fungal growth. Biomass conversion, pellet size and phytase activity were examined.

Thermostable Inulinases from Aspergillus Ficuum: Biochemical Characterization and Biotechnological Applications

1993
ABSTRACT Nine β -fructosidases were purified from a commercial inulinase preparation of the thermotolerant fungus Aspergillus ficuum. All enzymes were active towards inulin and sucrose, with an I/S ratio lower than 1 (except two enzymes). They were all glycoproteins with a high sugar content.
