Biobleaching of mechanical paper pulp using Streptomyces rutgersensis UTMC 2445 isolated from a lignocellulose-rich soil.

Our findings showed ability of S. rutgersensis UTMC 2445 in bleaching chemomechanical paper pulp. Also, two strains of Saccharothrix, a rare actinobacterium, with biobleaching activity were introduced. In the proposed method, there is no need to use purified enzymes, and biobleaching process can be done using the fermentation broth.
