Thermostable and alkaline-tolerant microbial cellulase-free xylanases produced from agricultural wastes and the properties required for use in pulp bleaching bioprocesses: A review

The number of possible applications of microbial xylanases in the pulp and paper industry is gradually increasing and several are approaching commercial use. However, the properties of commercial xylanases make them unsuitable for the real process of pulp bleaching. This industry needs xylanases whi...
