Biopulping Of Bagasse Using Different Types Of White Rot Fungi and Different Incubation Times

Abstract

Bagasse is fibrous residue that remains after the sugarcane is crushed to extract it’s juice. It mostly consists of lignocellulosic materials that may provide material for paper production through biopulping process. White rot fungi (WRF) is producers of extracellular ligninolytic enzymes that has the capability to mineralize lignin compounds. Three types of white rot fungi that were used in this study are Phanerochaete chrysosporium, Pleurotus ostreatus and Schizophyllum commune. Each of it was inoculated on bagasse substrate within 0, 15, and 30 days of incubation. This study was aimed to know the effect of interaction between white rot fungi and incubation time in the biopulping process and to investigate the most appropriate fungus and incubation time to produce good material for paper making obtained from sugarcane bagasse. The experimental design was done by using Completely Randomized Design (CRD) with a factorial pattern in two factors and analyzed by using Analysis of Variance (ANNOVA) then followed by Duncan’s Multiple Range Test (DMRT) on highly different significance effect of the treatment. The result of this study showed that S. commune is the most effective fungi to degrade highly lignin content (17.38% to 8.88%) at 30 days of incubation, while P. chrysosporium is the most effective fungi to lowering cellulose content in small amount (23.64% to 19.38%) during 30 days of incubation.

The growth of white rot fungi in the biodelignification process of sawdust of Sengon

“…PC is effectively used for delignification on sugarcane and wheat bran substrates 15 , while TV is reported to be effective on corn stalk 16 . PC is a white rot fungus that selectively degrades most of the lignin and hemicellulose 17 , while TV is a non-selective white rot fungus, meaning it can degrade lignin, hemicellulose, and cellulose 17,18 .…”
