Dictyoglomusis a genus ofbacterium,[4]given its own Phylum, called the Dictyoglomi. This organism is extremelythermophilic,meaning it thrives at extremely high temperatures. It ischemoorganotrophic,meaning it derives energy by metabolizing organic molecules. This organism is of interest because it elaborates an enzyme,xylanase,which digests xylan, a heteropolymer of the pentose sugarxylose.By pretreating wood pulp with this enzyme,papermanufacturers can achieve comparable levels of whiteness with much lesschlorinebleach.
It has been described asGram-negative,with a triple-layered wall.[5]
