Ramie solid waste as chips can be used as raw material for pulp. Ligninolytic enzymes of laccase widely used for pretreatment of the pulping process of ramie chips by biodelignification using laccase produced by Penicillium sp. LX/08 has been done. This study aims to obtain optimal concentrations of lignin and CuSO 4 as enzyme inducers to increase...
Article
Crude laccase was produced by using the fermentation method of solid state fermentation and employed fungus Marasmius sp and rice straw as support media. The kinetics of laccase was investigated by using the substrate of 2,2’-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). Laccase exhibits the maximum activity ( V m ) of 1.45 mM/min and M...

Recent years, there is an increased rate of non-wood fibers for pulp and paper industry. The non-wood fibers usually used for papermaking because of their fine paper making qualities, and in some countries the non-wood fibers are used to overcome the shortage of wood fibers. In Indonesia, one of the abundant sources of non-wood for pulp and paperma...

The research of white rot fungi application in biopulping ramie has been done to obtain the effective fungus. The study was conducted in 3 stages: biopulping, cooking, and manufacture of pulp handsheets. The biopulping of ramie was done by varying four species of fungi which were Phanerochaete chrysosporium, Marasmius sp., Trametes hirsuta, and Tra...

The increasing use of recycled paper by the paper industry to support the Green Industry in the Indonesian Pulp and Paper Industry. But technically, there are some disadvantages of recycled fiber usage such as low drainage rate in which boosted the high energy consumption on drying process. As already known, the drying process consumes the highest...

White rot fungi have an ability to degrade lignin by employing lignin-degrading enzymes i.e Lignin Peroxidase, Manganese Peroxidase and Laccase. Therefore, the fungi can be utilized on the pretreatment of biomass in pulp making (biopulping) and biobleaching. In this study, the pretreatment using White Rot Fungi of Marasmius sp. has been conducted o...

Natural fiber-reinforced composites can reduce the use of synthetic fibers and resins, making them more environmentally friendly. Bamboo fiber is a long fiber from non woody plant with a shorter growing season than wood. A study has been conducted to investigate the potential of bamboos, which are endemic in West Java, namely Tali bamboo (G. apus),...

An effort to produce laccase in a continous mode has been performed. Marasmius sp grown on rice straw have been employed in a packed bed bioreactor which had height and inner diameter of 24 cm and 2.5 cm, respectively. The effect of the liquid nutrient (Kirk medium) rate and the aeration rate were investigated. Both of them flew countinously by cou...

Laccase has been produced in a solid state fermentation (SSF) using white rot fungi and various lignocellulosic based substrates. White rot fungi used were Marasmius sp, Trametes hirsuta, Trametes versicolor and Phanerochaete crysosporium. The solid substrates employed in this research were collected from agriculture waste which were empty fruit bu...
