Furfural adalah salah satu bahan kimia penting yang dapat diubah menjadi berbagai bahan kimia seperti furfuryl alkohol dan asam levulinat. Furfural dapat diproduksi dari biomassa lignoselulosa dalam kondisi asam dengan mengkonversikan fraksi hemiselulosa ... see more

A membrane bioreactor was developed to counteract the inhibition effect of furfural in ethanol production. Furfural, a major inhibitor in lignocellulosic hydrolyzates, is a highly toxic substance which is formed from pentose sugars released during the aci... see more

Background: Xylitol is a five carbons polyol with promising medical applications. It can be obtained from chemical D-xylose reduction or by microbial fermentation of Sugarcane Bagasse Hemicellulosic Hydrolysate. For this last process, some microbial inhib... see more

The tolerances of filamentous Magellan fungi in peat were analyzed in the presence of structurally different petroleum hydrocarbons to assess their abilities for bioremediation in contaminated soils. Fungi on PDA (potato dextrose agar) and fresh peat plat... see more

This study examined the effect of blanching pretreatment on the drying kinetics, thermal degradation of phytonutrients and hydroxymethylfurfural (HMF) formation in pomegranate arils. Pretreated and untreated arils were dried in a cabinet dryer operated at... see more

In the present work, the degradation of different sugars, such as lac­tose, cellobiose, sucrose, galactose, glucose, fructose and xylose, was per­formed in batch reactor with subcritical water at temperature of 250 °C and reaction time of 1, 5 and 15 min.... see more

Biomaterials, chemicals and energy from renewable resources have been the object of considerable interest in recent years. Vegetable oils are one of the cheapest and most abundant biological sources available in large quantities and their use as starting ... see more

High-temperature (150–170 °C) pretreatment of lignocellulosic biomass with mineral acids is well established for xylan breakdown. Fe2+ is known to be a cocatalyst of this process although kinetics of its action remains unknown. The present work addresses ... see more

Telah dilakukan penelitian tentang hidrolisa bagas tebu menggunakan asam asetat sebagai katalis. Sebanyak 30 gram dihidrolisa dalam 300ml air yang mengandung katalis asam menggunakan  asetat sebesar 7 sampai 9% v/v dengan variabel waktu dan temperatu... see more
