Nitrogen explosive decompression pretreatment was tested on barley straw, aspen wood, and pine wood in a two-step approach. The approach aims to avoid the uncontrolled degradation of hemicellulose during recover high sugar yields from cellulose. Additionally, pretreated biomass filtered after each step with fine metal sieve so that fermentation hydrolysis inhibitors were removed. A total yield ...

The presence of anglesite (PbSO4) in complex sulfide ores negatively affects the separation Cu-Pb sulfides and sphalerite (ZnS) due to lead activation, PbSO4 rejected tailings dams contaminates surrounding environment with lead. To address these problems, this study investigated application ethylene diamine tetra acetic acid (EDTA) pretreatment extracting ZnS flotation recovery extracted Pb2+ a...

High throughput pretreatment (HTPH) and enzymatic hydrolysis systems are now vital for screening large numbers of biomass samples to investigate biomass recalcitrance over various pretreatment and enzymatic hydrolysis conditions. Although hydrothermal pretreatment is currently being employed in most high throughput applications, thermochemical pretreatment at low and high pH conditions can offe...

  Although cisplatin is one of the most effective cancer drugs which is widely used in the treatment of various neoplasms, its side effects, especially vomiting may limit its use. It has been demonstrated that cytotoxic drugs lead to a sudden release of serotonin (5-HT). The following study was performed to determine the possible interactions of cisplatin with 5-HT receptors. In this study, the...

Abstract Introduction: Resent studies have been shown beneficial effects of hyperoxia pretreatment against ischemia-reperfusion injury in different organs. The aim of the present study was to investigate early and late effects of normobaric hyperoxia (≥95% O2) pretreatment on ischemia-reperfusion injuries in isolated rat hearts. Methods: Following 60 and 180 minutes of hyperoxia, rat hearts w...

BACKGROUND The recalcitrance of lignocellulosic biomass is a major limitation for its conversion into biofuels by enzymatic hydrolysis. The use of a pretreatment technology is an essential step to diminish biomass recalcitrance for bioethanol production. In this study, a two-step pretreatment using hydrothermal pretreatment at various temperatures and alkali fractionation was performed on eucal...

UNLABELLED BACKGROUND Previous research on alkaline pretreatment has mainly focused on optimization of the process parameters to improve substrate digestibility. To achieve satisfactory sugar yield, extremely high chemical loading and enzyme dosages were typically used. Relatively little attention has been paid to reduction of chemical consumption and process waste management, which has prov...

Microalgae, which accumulate considerable carbohydrates, are a potential source of glucose for biofuel fermentation. In this study, we investigated the enzymatic hydrolysis efficiency wet microalgal biomass compared with freeze-dried and oven-dried biomasses, both without an acidic pretreatment. With dilute sulfuric acid pretreatment followed by amy (α-amylase amyloglucosidase) cellulase hydrol...

The present study aims to describe an innovative approach that enables the system achieve high yielding for biohydrogen (bio-H2) production using xylose as a by-product of lignocellulosic biomass processing. A hybrid optimization technique, structural modelling, desirability analysis, and genetic algorithm could determine optimum input factors maximize useful biogas parameters, especially bio-H...
