A. niger strain N402 (cspA1) ATCC 64974) is a laboratory work horse strain that has been extensively used as a master strain for the generation of regulatory and structural mutants. Strain N402 is a derivative of the wild type strain N400 (CBS 120.49, NRRL3, ATCC 9029) and was obtained through two successive rounds of low-dosed UV mutagenesis.
