Enzymatic hydrolysis of corn starch after extraction of corn oil with ethanol
Simultaneous corn oil extraction and alcohol dehydration, a solvent corn-milling process developed in our laboratory, was tested on a pilot scale to recover corn oil. Over 92% of the corn oil was extracted by ...

Recovery of yeast invertase from ethanol fermentation broth
Ethanol fermentation broth produced by an aggregated form ofSaccharomyces uvarum strain contained invertase when sucrose-based raw materials were used. The amount of invertase in the borth was in the range of 1.4...

Production, separation and purification of yeast invertase as a by-product of continuous ethanol fermentation
A strain of Saccharomyces uvarum produced extracellular invertase in a chemostat reactor using a medium containing corn steep liquor and sugars. The production of yeast invertase increased with increase in corn s...

Prediction of bed height in a self-aggregating yeast ethanol tower fermenter
A packed bed region and a mixed region were observed in an ethanol tower fermenter packed with flocs of self-aggregating yeast. Sizes of yeast flocs were 2–3 mm and 0.2–0.3 mm in diameter in the packed bed reg...

A multichamber tower fermentor for continuous ethanol fermentation with a self-aggregating yeast mutant
A multichamber tower fermentor, with a combined working volume of 30 L, was used to ferment sugar cane molasses to ethanol using a self-aggregating yeast mutant, Saccharomyces uvarum U4, derived from Saccharom...

Integration and expression of theEscherichia coli xylose isomerase gene inSchizosaccharomyces pombe
The xyclose isomerase gene inEscherichia coli was cloned complementarily into a Leu2-negativeSchizosaccharomyces pombe mutant (ATCC 38399). The subsequent integration of the plasmid into the chromosomal DNA of th...

Metabolism of d-xylose in Schizosaccharomyces pombe cloned with a xylose isomerase gene
The Escherichia coli xylose isomerase gene was transformed into Schizosaccharomyces pombe for direct d-xylose utilization. In order to understand d-xylose metabolism and determine the limiting factors on d-xylose...

Environmental effects on D-xylose fermentation bySchizosaccharomyces pombe
Many efforts have been made to convert D-xylose to ethanol. Studies include a search in nature for xylose-fermenting yeasts; mutagenesis of xylose-utilized yeasts such asPachysolen trannophilus (1),Candida sp. (2...

Effect of inoculum on yeast cell aggregation
Saccharomyces uvarum, Kluyveromyces marxianus, Saccharomyces cerevisiae, and Candida sp. were induced to form cell aggregates in a column. The conditions for this induction were high cell density and slow flow r...

Quantitative production of xylitol from D-xylose by a high-xylitol producing yeast mutant Candida tropicalis HXP2
Xylitol was produced as a metabolic by-product by a number of yeasts when grown on medium containing D-xylose as carbon and energy sources. Among the yeast strains tested, a mutant strain of Candida tropicalis (H...

Conversion of hemicellulose carbohydrates
Hemicellulose can be converted to a variety of useful products. There are two approaches to hemicellulose bioconversion; hemicellulose can be directly converted, or the hemicellulose-derived carbohydrates can ...
