slurries of rice-straw cellulose (obtained by delignification and removal of hemicelluloses from the powdered raw material) were subjected to ultrasonic waves at different intensities for various times (constant temperature). susceptibility of the samples to cellulose-hydrolysis increased initially with pretreatment time, reaching a maximum or a constant level thereafter. maximum glucose yield ...

The effect of different extraction methods rosemary leaves on the total phenolic content (TPC), and antioxidant activity extracts was herein investigated. Firstly, solid-liquid conventional (CEM) microwave-assisted (MAE) were implemented in an effort to identify solvent microwave irradiation extract quality. obtained from CEM at room temperature, using ethanol/water 95:5 v/v, showed highest (IC...

HIGHLIGHTS C. cubensis-P. pinophilum enzyme blend resulted in high levels of synergy Mild hydrothermal pretreatment reduced the hemicellulases requirement hydrolysis The best results were obtained by enzymatic H60-SCB saccharification

To investigate the effects of biomass feedstock and pretreatment method on the enzyme requirement during hydrolysis, swichgrass and coastal Bermuda grass pretreated using H2SO4, NaOH, and Ca(OH)2 at the optimal conditions were subjected to enzymatic hydrolysis using two enzyme combinations: NS 50013 + NS 50010 and Cellic CTec + Cellic HTec. The enzyme loadings were optimized, and correlations b...

We investigated the feasibility of anaerobic codigestion of sewage sludge and rice straw. Laboratory-scale mesophilic and thermophilic digesters were operated with hydraulic retention times of 20 and 15 days, respectively. The feeding ratio of sewage sludge and rice straw was 1:0.5 based on the total solids (TS). Before digestion, the rice straw was ground to ca. 5 mm in length (grinding pretre...

This study investigated the effect of CaO2 pretreatment on sulfonamide antibiotics (SMs) remediation by Chlorella sp. Results showed that a dose ranging from 0.05 to 0.1 g/g biomass was best and led higher SMs removal efficacy 5–10% than control. The contributions made cometabolism in were very similar. Bioassimilation could remove 24% sulfadiazine (SDZ) sulfamethazine (SMZ), accounted for 38% ...

Ginger is one of the commonly used spices that has been exhibited to have pharmaceutical activities. These therapeutic properties are mainly attribute to gingerols and shogaols. To extract these bioactive compounds, subcritical water extraction (SWE) was employed as a green method. The influence of adding co-solvents, temperature, retention time and particle size on extraction yield were invest...

Removal of enzyme inhibitors released during lignocellulose pretreatment is essential for economically feasible biofuel production. We tested bio-abatement to mitigate enzyme inhibitor effects observed in corn stover liquors after pretreatment with either dilute acid or liquid hot water at 10% (w/v) solids. Bio-abatement of liquors was followed by enzymatic hydrolysis of cellulose. To distingui...
