Dictyoglomus is a genus of xylanase, which digests xylan, a heteropolymer of the pentose sugar xylose. By pretreating wood pulp with this enzyme, paper manufacturers can achieve comparable levels of whiteness with much less chlorine bleach.

It has been described as Gram negative, with a triple-layered wall.[4]
