A xylanase from Aspergillus kawachii, active at pH 2.0–2.5, was found to be suitable for improvement of bleachability. Due to the low working pH of the xylanase, the metal cations were also removed and thus the metal removal stage using chelating agents could be omitted. The use of acid-tolerant xylanase is especially beneficial prior to ozone or chlorine dioxide bleaching stages due to the minimization of pH adjustment steps during bleaching.
