    Besides increasing paper strength, fungal treatments can also reduce the electrical energy needed for fiberizing chips during mechanical pulping. Fungal species, chip movement, and treatment duration . The symptoms commonly include shortness of breath, wheezing, coughing, runny nose, and headaches. Fungal balls, or aspergilloma, can form when hyphal colonies collect in the lungs (Figure ). The fungal hyphae can .

It is the primary reason why the mortality rate is high in people with meningitis. The usual clinical features of neonatal meningitis secondary .

    In the second stage after refining, the pulp is screened, cleaned, and most of the process water is removed in preparation for paper making. Bleaching Process Raw pulp contains an appreciable .   The enzymatic treatment can be carried out at process temperatures of from 20° C. to 80° C., for example between 40° C. and 60° C. The enzymatic treatment can be carried out at a pH of from about 2 to about The treatment time can be from 30 minutes to 10 hours. Other temperatures, pHs and or times can .
