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 ...

Simultaneous Saccharification and Fermentation and Partial Saccharification and Co-Fermentation of Lignocellulosic Biomass for Ethanol Production

2009
Ethanol production by fermentation of lignocellulosic biomass-derived sugars involves a fairly ancient art and an ever-evolving science. Production of ethanol from lignocellulosic biomass is not avant-garde, and wood ethanol plants have been in existence since at least 1915. Most current ethanol production relies on starch- and sugar-based crops as the

Enzymic saccharification of sugar beet pulp

Biotechnology and Bioengineering, 1984
AbstractCulture filtrates of Talaromyces emersonii UCG 208 grown on beet pulp can convert the polysaccharide components of this agricultural waste to soluble sugars. The saccharification process is facilitated if the pulp is milled or incubated with alkali or peracetic acid before addition of enzyme.

The complete enzymatic saccharification of agarose and its application to simultaneous saccharification and fermentation of agarose for ethanol production

Bioresource Technology, 2012
A sugar platform equipped with acetic acid, multiple agarases and neoagarobiose hydrolase (NABH) converted recalcitrant agar polysaccharide into monosugars, which was evaluated by simultaneous saccharification and fermentation (SSF). The sugar platform was divided into chemical liquefaction and enzymatic saccharification.

The pretreatment effect on wheat straw saccharification

Acta Biotechnologica, 1988
AbstractEnzymatic hydrolysis of cellulose is potentially an attractive method for converting cellulose into glucose which can then be used as a chemical feed or as a growth substrate for a number of microorganisms to produce microbial products.An enzymatic hydrolysis of wheat straw with cellulase preparation “Trichocease” was made. The wheat straw used

Pretreatment and Enzymatic Saccharification of Corn Fiber

Applied Biochemistry and Biotechnology, 1999
Corn fiber consists of about 20% starch, 14% cellulose, and 35% hemicellulose, and has the potential to serve as a low-cost feedstock for production of fuel ethanol. Several pretreatments (hot water, alkali, and dilute acid) and enzymatic saccharification procedures were evaluated for the conversion of corn fiber starch, cellulose, and hemicellulose to

A calorimetric assay for enzymatic saccharification of biomass

Enzyme and Microbial Technology, 2010
A limited selection of assay and screening methodologies for cellulolytic enzymes has been stated as a restriction in biomass research. In this report we test the potential of isothermal calorimetry for this purpose. The primary observable in this technique (the heat flow in Watts), scales with the rate of hydrolysis, and unlike other approaches, it ...

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

Saccharification of steam‐exploded poplar wood

Biotechnology and Bioengineering, 1991
AbstractEffects of time, temperature, and pH during the steam explosion of poplar wood were studied with the aim of optimize both pentoses recovery and enzymatic hydrolysis efficiency. Steam explosion of acid impregnated wood chips allowed the recovery of 70% of potential xylose as monomers (217°C, 120 s) Enzymatic hydrolysis of pretreated fiber with ...

A New Saccharification Process of Lignocellulosics

2010
A single step saccharification of lignocellulosics using a new thermochemical process has studied to develop a simple and rapid saccharification method. Wood powder of Liriodendron tulipifera and Populus alba x glandulosa were used as lignocellulosic materials.
