Saccharification and fermentation of pretreated banana leaf waste for ethanol production

Simultaneous Saccharification and Fermentation of Cassava Waste for Ethanol Production

Simultaneous Saccharification and Fermentation of Waste Textiles for Ethanol Production

Ethanol production in a simultaneous saccharification and fermentation (SSF) process using waste textiles as feedstock was studied. The dissolution pretreatment of waste textiles in ortho-phosphoric acid resulted in at least 2 fold improvement in enzymatic hydrolysis rate and reducing sugar yield. The reducing sugars obtained from dyed or discolored waste textiles by cellulase hydrolysis demons...

High titer ethanol production from SPORL-pretreated lodgepole pine by simultaneous enzymatic saccharification and combined fermentation.

Lodgepole wood chips were pretreated by sulfite pretreatment to overcome recalcitrance of lignocelluloses (SPORL) at 25% solids loading and 180 °C for 20 min with sulfuric acid and sodium bisulfite charges of 2.2 and 8 wt/wt% on an oven-dry wood basis, respectively. The pretreated wood chips were disk-milled with pretreatment spent liquor and water, and the solid fraction was separated from the...

A Bacterial Laccase for Enhancing Saccharification and Ethanol Fermentation of Steam-Pretreated Biomass

Different biological approaches, highlighting the use of laccases, have been developed as environmentally friendly alternatives for improving the saccharification and fermentation stages of steam-pretreated lignocellulosic biomass. This work evaluates the use of a novel bacterial laccase (MetZyme) for enhancing the hydrolysability and fermentability of steam-exploded wheat straw. When the water...

The Simultaneous Saccharification and Fermentation of Pretreated Woody Crops to Ethanol

Four promising woody crops (Populus maximowiczii x nigra (NE388), P. trichocarpa x deltoides (Nll), P. tremuloides, and Sweetgum Liquidambar styraciflua) were pretreated by dilute sulfuric acid and evaluated in the simultaneous saccharification and fermentation (SSF) process for ethanol production. The yeast Saccharomyces cerevisiae was used in the fermentations alone, and in mixed cultures wit...
