    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...

    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...

    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...

    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...
