Mutant of a Xylanase-producing Strain of Aspergillus niger in Solid State Fermentation by Low Energy Ion Implantation

Article

Summary

In order to obtain an industrial strain with higher xylanase production, the original strain of Aspergillus niger was mutated by N+ implantation (10 keV, 1.04 · 1015–2.08 · 1015 ions/cm2), and a mutant P602 was obtained. The mutant showed xylanase production increased from 2989 to 6320 IU/g and the fermentation time was decreased from 72 h to 64 h. The fermentation temperature range was 28–32 °C which was a little wider than the original strain.
