Characterisation of biologically pretreated raw materials for biopulping process.

ABSTRACT

Biopulping, the treatment of wood chips by white rot fungi and subsequent chip refining is envisioned as a method for saving energy and making a stronger paper product. The present study aims to find suitability of two fungal isolates Phellinus pectinatus and Daedaleopsis confragosa for the process of biopulping and the characteristion of the biologically pretreated raw materials for biopulping. Two combinations of raw samples, Bamboo wood shavings and Bamboo wood shavings Sorghum halepense culm were prepared and subjected to four different pretreatment. Daedaleopsis confragosa was found to be effective in biopulping with a supplement of Potato dextrose broth medium to the raw material.
