Abstract

Cellulosic products having a high hemicellulose to lignin weight ratio are obtained by extracting a cellulosic composition with basic ethanol-water solution having a pH between about 12 and about 14 at a temperature between about 15.degree. and about 70.degree. C. and for a time period between about 2 and about 80 hours.

Fermentation method producing ethanol

Patent Wang, Daniel; Dalal, Rajen

Ethanol is the major end product of an anaerobic, thermophilic fermentation process using a mutant strain of bacterium Clostridium thermosaccharolyticum. This organism is capable of converting hexose and pentose carbohydrates to ethanol, acetic and lactic acids. Mutants of Clostridium thermosaccharolyticum are capable of converting these substrates to ethanol in exceptionally high yield and with increased productivity. Both the mutant organism and the technique for its isolation are provided.

Method of saccharifying cellulose

Patent Johnson, Eric; Demain, Arnold; Madia, Ashwin

A method of saccharifying cellulose by incubation with the cellulase of Clostridium thermocellum in a broth containing an efficacious amount of a reducing agent. Other incubation parameters which may be advantageously controlled to stimulate saccharification include the concentration of alkaline earth salts, pH, temperature, and duration. By the method of the invention, even native crystalline cellulose such as that found in cotton may be completely saccharified.

Improved alcohol production employing SSF with thermotolerant yeast

Conference Tsao, G; Cao, N; Gong, C

Simultaneous saccharification and fermentation (SSF) involves the enzymatic hydrolysis of cellulose and the yeast fermentation of sugars to ethanol simultaneously in the same reactor. For the effective SSF process to produce ethanol from lignocellulose, it is required to remove the physical and chemical barrier around cellulose fibers and make cellulose more accessible to cellulose. Furthermore, it is preferred to have the compatible fermentation and saccharification conditions (e.g., temperature and pH). The process for pretreatment of lignocellulosic biomass involves the steeping in ammonia solution to remove lignin followed by dilute acid (1%, w/w) hydrolysis of hemicellulose fraction. The ammonia steeping removesmore »« less
New approach for the production of cellulose acetate: acetylation of mechanical pulp with subsequent isolation of cellulose acetate by differential solubility

Thesis/Dissertation Barkalow, D

A heretofore uninvestigated approach to the production of cellulose acetate is the acetylation of mechanical pulp with subsequent isolation of the cellulose derivative by differential solubility. The mechanical pulp is produced by refining aspen wood chips in a disc-refiner. Two conventional acetylation techniques, the fibrous and solution process, are employed to acetylate all components of the pulp. The cellulose acetate is isolated from the acetylated lignin and hemicellulose by dissolving in dichloromethane/methanol (9:1, v/v). The advantage of this new approach is that the high costs involved in using an extensively purified dissolving pulp are avoided. Both procedures yield a productmore »« less
