Cocoa pod husks are a type of biomass that is still poorly explored. This work was carried out as part the optimization delignification process for this residue with potassium hydroxide, to maximize reducing sugars content. Screening potentially influencing factors showed solvent ratio and temperature had greatest effect on process. Optimization these using composite central plan revealed quadr...

Abstract Background Hydrogen peroxide–acetic acid (HPAA) is widely used in pretreatment of lignocellulose because it has a good capability selective delignification. However, high concentration (more than 60%) HPAA increases the cost and risk explosion. In this work, alkaline post-incubation was employed to decrease loading improve saccharification poplar. Results Pretreatment with 100% removed...

Indonesia is a country that has the most energy sources in Southeast of Asia and fifth Asia-Pacific subsequent to China, India, Japan South Korea. Energy usage 2016 was still dominated by 47% fuel oil. If increases continuously, sustenance resilience will be plagued. Therefore, there necessary utilize alternative would earth-friendly as well New Renewable (EBT) like bioethanol. Bioethanol can p...

Some pretreatments that swell and/or open the structure of wood fibers could increase the effectiveness of a biobleaching process, allowing for an industrial application. To this end, a chemical pretreatment (urea, U), a physical pretreatment (refining, R), and their combinations (RU and UR) were optimized to evaluate and compare their enhancement of the LE biobleaching sequence (laccase-mediat...

Aiming to fulfil the sustainability criteria of future biorefineries, a novel biomass pretreatment combining natural deep eutectic solvents (NaDESs) and microwave (MW) technology was developed. Results showed that NaDESs have high potential as green for lignin fractionation/recovery sugar release in following enzymatic hydrolysis. A new class derived (LigDESs) also investigated, showing promisi...

A comprehensive study was carried out to assess the efficiency of different chemicals on pretreatment plant biomass, corn cobs. The assessed based its effect subsequent hydrolysis biomass for conversion fermentable sugars. Both alkali- and acid-based pretreatments were under optimized conditions avoid formation inhibitors also yield more Among used, 2% NaOH (w/v) found be effective with deligni...
