Abstract
An exoenzyme mixture obtained from solid-state fermentation of straw b y Lentinus edodes was used to treat wheat straw in a rotary drum biore actor. After 24 h incubation under different conditions (temperature, cellulase inhibition) and subsequent pulping of the pre-treated straw, the degrees-SR freeness, breaking length, and burst index of the pape r handsheets showed that the enzymic treatment reduced the energy need s for the refining treatment by about 50%. Its influence on freeness, breaking length, and burst index is reported.
