Abstract:
... Autohydrolysis is vastly used in industry to extract hemicellulose from lignocellulosic biomass. Despite their potential end-use applications, lignocelluloses cannot be completely extracted from hydrolysate as they may deposit on the equipment during the hydrolysis process. This study tends to investigate the physicochemical properties and adsorption behavior of the components of hydrolysates prod ...

A rapid, low-cost, scalable flocculation technology, using either potash alum (for culture pH < 8.5), or potash alum with hydrochloric acid (for culture pH > 8.5), is employed to harvest algal biomass in less than thirty minutes. The gaseous CO₂ (0.04–5%) and acetic acid glacial added during mixotrophic cultivation produce hydrogen and acetate ions that react with hydrolysed potash alum to form ch ...

Abstract:
... The inhibitory effect of toxic byproducts mainly derived from the pretreatment of lignocellulosic biomass is one of the limiting factors hindering industrial application. In this work, a simple yet practicable aeration strategy was proposed to enhance microbial tolerance to inhibitors, including formic acid, acetic acid, furfural, and 5-hydroxymethyl furfural (5-HMF). Batch fermentation by Kluyver ...

After being pretreated in 60 wt% LiBr at 130 °C for 2 h, cellulose crystallinity as well as degree of polymerization (DP) decreased. It was found that 91.3% yield of pretreated cellulose was removed from MSHs by filteration followed by being hydrolyzed into gluco ...
