Countercurrent enzymatic saccharification of cellulosic biomass
Biomass and Bioenergy, 2016Abstract At pH 4.8 and 50 °C, semi-continuous countercurrent saccharification was performed using α-cellulose. Every second day, solids and liquids were transferred countercurrently and liquid samples were taken to determine sugar concentration in each stage.

Enzymatic Saccharification of Lignocellulosic Biomass
2012The conversion of polymers present in the lignocellulosic biomass into fermentable sugars can be achieved through physical/chemical and enzymatic pretreatments. The microbial conversion of biomass to bioenergy will be cost-effective only if all of the components in the biomass are converted into value-added products.

Simultaneous Saccharification and Cofermentation of Peracetic Acid-Pretreated Biomass
Applied Biochemistry and Biotechnology, 2000Previous work in our laboratories has demonstrated the effectiveness of peracetic acid for improving enzymatic digestibility of lignocellulosic materials. The use of dilute alkali solutions as a pre-pretreatment prior to peracetic acid lignin oxidation increased carbohydrate hydrolysis yields in a synergistic as opposed to additive manner ...

Enzymatic saccharification of pretreated rice straw and biomass production
Biotechnology and Bioengineering, 1986AbstractA comparative study on the saccharification of pretreated rice straw was brought about by using cellulase enzyme produced by Aspergillus terreus ATCC 52430 and its mutant strain UNGI‐40. The effect of enzyme and substrate concentrations on the saccharification rate at 24 and 48 were studied. A syrup with 7% sugar concentration was obtained with

Simultaneous saccharification and fermentation of lime-treated biomass
Biotechnology Letters, 2001Simultaneous saccharification and fermentation (SSF) was performed on lime-treated switchgrass and corn stover, and oxidatively lime-treated poplar wood to determine their compatibility with Saccharomyces cerevisiae. Cellulose-derived glucose was extensively utilized by the yeast during SSF.

Simultaneous Saccharification and Fermentation of Lignocellulosic Biomass
2017In recent years, with the growing concerns over the depletion of natural resources and food security, researchers are focusing on abundantly available non-food crops such as lignocellulosic biomass as alternative reserves for bioenergy. Since lignocellulosic biomass are a rich source of carbohydrates they can be used to produce various biological ...

Simultaneous Saccharification and Fermentation of Cellulosic Biomass to Acetic Acid
Applied Biochemistry and Biotechnology, 2000A strain of Clostridium thermoaceticum (ATCC 49707) was evaluated for its homoacetate potential. This thermophilic anaerobe best produces acetate from glucose at pH 6.0 and 59 degrees C with a yield of 83% of theoretical. Enzyme hydrolysis of two substrates, a-cellulose and a pulp mill sludge, yielded 68% and 70% digestion, respectively.
