Saccharification of explosively dried corn

Biotechnology and Bioengineering, 1986
AbstractVery rapid or explosive drying of grains such as corn leads to obvious physical changes in the macrostructure of the grain kernel, probable alteration in starch molecular structure, and reduction in starch average molecular weight. These changes lead to greater susceptibility to attack by liquefying and saccharifying enzymes. Rates of formation

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.

Comparison of hydrogen fluoride saccharification of lignocellulosic materials with other saccharification technologies

Energy in Agriculture, 1983
Abstract Laboratory investigations have been conducted for the past year in the MSU-DOE Plant Research Laboratory in collaboration with Chemical Engineering at Michigan State University on the hydrogen fluoride (HF) saccharification of cellulose and wood. Our work is an extension of the work done by Fredenhagen in Germany reported in 1933.

Increased Saccharification Yield by Cellulases Coupling

International Journal of Solar Energy, 1986
In many cellulase preparations the enzymatic activity is not well balanced and the catalytic attack of the cellulose is limited. The purpose of this study was to investigate the possibility of simultaneously using two cellulases from distinct sources for improving the rate of hydrolysis as alternative to other costly techniques which require enzyme ...

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 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 ...

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.

Simultaneous saccharification and fermentation of cellulose: Effect of ethanol on enzymatic saccharification of cellulose

Biotechnology and Bioengineering, 1985
AbstractIt was confirmed that simultaneous saccharification and fermentation are effective for accelerating enzymatic saccharification of cellulose. In this work, the effects of ethanol on the saccharification of tissue paper by Trichoderma cellulase (Meicelase CEPB) have been investigated. The following results were obtained.

Enzymatic Saccharification of Defatted Corn Germ*

Biotechnology Letters, 2004
Commercial defatted germ from wet milled corn was efficiently saccharified by a crude enzyme preparation from Aureobasidium sp. with yields of up to 200 mg glucose, 140 mg xylose, and 130 mg arabinose per g germ. These yields exceeded sugar composition estimates based on trifluoroacetic acid digestion. Neither chemical nor mechanical pretreatments were
