Nitration of saccharification lignin

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1958
1. A study was made of the nitration of saccharification lignin with a mixture of nitric and sulfuric acids having various water contents (5–16%), with a mixture of nitric acid and crystalline phosphoric acid, with nitric acid in a medium of acetic anhydride, and with nityric acid of sp.gr. 1.52.

Modeling Simultaneous Saccharification and Fermentation of Softwood

Applied Biochemistry and Biotechnology, 2002
Simultaneous saccharification and fermentation (SSF) of wood has been modeled for the past 15-20 years, but the substrates used for model evaluation have so far not included pretreated softwood. In the present study, data from lab-scale batch SSF of SO2-impregnated, steam-pretreated spruce chips were used to evaluate a model found in the literature ...

Saccharification of bamboo carbohydrates for the production of ethanol

Biotechnology and Bioengineering, 1983
AbstractBamboo carbohydrates were hydrolyzed with commercial amylases and a mixture of fungal culture broths containing cellulolytic and hemicellulolytic enzymes. The effects of cooking temperature and the size of fiber particles were also investigated. It was found that the higher the cooking temperature, the higher the rate of sugar formation and the

Continuous enzymatic liquefaction of starch for saccharification

Biotechnology and Bioengineering, 1982
AbstractA process was explored for continuous enzymatic liquefaction of corn starch at high concentration and subsequently saccharification to glucose. The process appears to be quite efficient for conversion of starch to glucose and enzymatic liquefaction and should be readily adaptable to industrial fermentation processes.

Measurement of saccharification by cellulases

Enzyme and Microbial Technology, 1985
Abstract Techniques for screening and measurement of the cellulase complex are reviewed under qualitative or quantitative headings, with emphasis on recent methods of analysis. Appropriate substrates are considered for the constituent enzymes of the complex in the light of physical constraints on hydrolysis.

Saccharification of bagasse pith

Journal of Applied Chemistry and Biotechnology, 1977
AbstractWork is reported here on a process for the saccharification of bagasse pith, as the second part of a study of bagasse processing aimed at establishing an integrated industry. A method for pentose preparation from bagasse pith is designed on the basis of the conclusions reached in the first part of the study.

Enzymic saccharification of pretreated wheat straw

Biotechnology and Bioengineering, 1985
AbstractStudies of pretreatment of wheat and its subsequent saccharification by Trichoderma reesei cellulases are reported. Steam explosion was found to be the most effective of the pretreatment methods tested. Data are presented describing the effect of enzyme and substrate concentration on the rate and degree of hydrolysis.

Modeling cassava starch saccharification with amyloglucosidase

Applied Biochemistry and Biotechnology, 1996
A solution of α-amylase liquefied cassava starch, 30% (w/v), was saccharified with amyloglucosidase at 45°C, pH 4.5, in a batch reactor in the presence and absence of added glucose. Reactor conversion results were modeled with a multisubstrate model that considers intermediate dextrins of starch hydrolysis, reversibility of some reactions, substrate ...

Rapid saccharification for production of cellulosic biofuels

Bioresource Technology, 2014
The economical production of biofuels is hindered by the recalcitrance of lignocellulose to processing, causing high consumption of processing enzymes and impeding hydrolysis of pretreated lignocellulosic biomass. We determined the major rate-limiting factor in the hydrolysis of popping pre-treated rice straw (PPRS) by examining cellulase adsorption to
