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...

Continuous ethanol production using induced yeast aggregates
The induction of yeast cell aggregates in a column reactor was initiated by packing yeast cell paste of Saccharomyces uvarum into the column, and then YMP broth was fed into the column from the bottom at a linear...

Effect of oxygen uptake rate on ethanol production by a xylose-fermenting yeast mutant,Candida sp. XF217
The fermentation of D-xylose by theCandida sp. mutant XF217 was studied at different oxygen uptake rates by controlling dissolved oxygen tension or agitation rate. The ethanol yield increases as the oxygen uptake...

d-Xylose metabolism by mutant strains of Candida sp.
The first step in the metabolism of d-xylose by yeasts and mycelial fungi was found to be the reduction of d-xylose to xylitol, a reaction catalyzed by NADPH-linked d-xylose reductase. This step is followed by th...

Production of ethanol from wood hemicellulose hydrolyzates by a xylose-fermenting yeast mutant, Candida sp. XF 217
Ethanol was produced from wood chip hemicellulose hydrolyzate by a xylose-fermenting yeast mutant, Candida sp. XF 217. The rates of D-xylose consumption and ethanol production were greater under aerobic than ferm...

D-xylulose fermentation in yeasts
With pure D-xylulose as substrate, Schizosaccharomyces pombe produced ethanol in good yield with low quantities of polyols as by-products. Saccharomyces cerevisiae was found to be a good alcohol producer in gluco...

Direct fermentation of D-xylose to ethanol by a xylose-fermentating yeast mutant, Candida sp XF 217
A mutant strain of Candida sp. XF 217, was found to produce ethanol from D-xylose aerobically as well as anaerobically. The rate of ethanol production under aerobic conditions was greater, indicating an oxygen re...

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...

Direct fermentation of cellulose to ethanol by a cellulolytic filamentous fungus, Monilia sp.
A saprophytic filamentous fungus, Monilia sp., isolated from bagasse compost was found to utilize many polysaccharides (including cellulose) and to produce cellulases and hemicellulases. Monilla sp. also fermente...

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 ...
