Aspergillus niger is one of the black aspergilli (Aspergillus section Nigri; Gams et al. 1985). Varga et al. (2007) described A. brasiliensis as a widespread segregate from A. niger, based on gene sequence differences and extrolite production profile. It is probable that many records of A. niger refer to a segregate species Glucose oxidase from Aspergillus niger is a dimer consisting of 2 equal subunits with a molecular mass of 80 kDa each. Each subunit contains one flavin adenine dinulceotide moiety and one iron. The enzyme is a glycoprotein containing ~16% neutral sugar and 2% amino sugars. The enzyme also contains 3 cysteine residues and 8 potential sites for N. The cultural and nutrient requirements of Aspergillus niger for production of α-amylase in production media containing different pH, temperature, incubation period, metal ion concentrations, surfactants, carbon sources and nitrogen sources were quantified in present study. The optimum pH, temperature and incubation period for enzyme production were 5.0, 30°C and 5th day, respectively Abstrat Aspergillus spp are all around us, in the soil and in material decomposing. This means that we're constantly inhaling it, making the respiratory system the way this fungus gets into our bodies.
