Genes for xylanases from two different glycosyl hydrolase families from the bacterium Dictyoglomus thermophilum Rt46B.1 have been isolated and over-expressed in bacterial and fungal hosts. XynB has shown greater promise than XynA as a bleach-boosting agent for both pine and eucalypt kraft pulps in ECF and TCF sequences. Because of the limits of natural biodiversity, further development of XynB for increased pH range is being explored by enzyme evolution techniques which combine in vitro mutagenesis and recombination. Simulations using in silico population genetics are also being implemented to explore the available sequence space.
