Abstract

Biological system offers more enviromentally friendly and energy saving in the paper making technology. One of the most preferred was using white rot fungi Phanerochaete chrysosporium. The objective of this research was to study the effect of glucose and yeast extract to the amount of the degraded lignin in the solid waste of starch aren industry. The dried solid wastes weres added with culture medium, glucose or yeast extract and then sterilized. All systems was adjusted at pH 4. A portion of fungi suspension then mixed with the substance then it incubated at 40 oC for 30 days. The lignin and cellulose content were analysis every five days. It observe that the lignin content decreases with incubation time. The cellulose content also decreses with incubation time too, but less quantity than the lignin. More glucose and extract yeast added to the waste, more lignin can be degraded but less in losing cellulose.
