The continuous increase in the world energy and chemicals demand requires the development of sustainable alternatives to non-renewable sources of energy. Biomass facilities and biorefineries represent interesting options to gradually replace the present industry based on fossil fuels. Lignocellulose is the most promising feedstock to be used in biorefineries. From a sugar platform perspective, ...

The ability of two natural phenols to act as mediators of the recombinant Myceliophthora thermophila laccase (MtL) in eucalypt-pulp delignification was investigated. After alkaline peroxide extraction, the properties of the enzymatically-treated pulps improved with respect to the control. The pulp brightness increased (3.1 points) after the enzymatic treatment with MtL alone, but the highest im...

Abstract Bagasse has the potential to generate alternative energy resources such as bioethanol owing its lignocellulose structure. This research aims for utilizing bagasse raw material producing bioethanol. The process consists of delignification, hydrolysis, fermentation and distillation using biocatalyst namely Fungi Dekkera bruxellensis yeast Saccharomyces cerevisiae . Delignification was co...

Pretreatment of biomass is an extremely important step in a commercial biorefinery. For realization of lignocellulosic biomass as an alternative fuel source to occur, a fundamental understanding and critical investigation of the chosen pretreatment are essential. In this work, green liquor (GL) pretreatment of four plant species, namely Masson pine, poplar, moso bamboo, and miscanthus, was inve...

Abstract Lignocellulose biomass was a potential feedstock for biobased chemicals substituting fossil-based chemicals. Oil Palm Empty Fruit Bunch (EFB) is the largest lignocellulose from oil palm waste. contains cellulose, hemicellulose and lignin. Pretreatment one of steps in bioconversion material. aims to reduce lignin because can inhibit conversion. The objection this research conduct pretre...
