    摘要： An improved process for the continuous production of butanol by fermentation of carbohydrates with C. acetobutylicum is disclosed. This process combines continuous inoculum production at a high dilution rate and cycling the fermentation broth through a material which adsorbs butanol whereby a vigorous cell population is maintained in the fermentation reactor for extended periods of time.

    摘要： Process of enzymatically converting glucose to fructose wherein a glucose-containing solution is passed, under specific conditions, through a bed composed of an immobilized glucose isomerase in a fine, particulate form and non-porous beads or granular inert material such as polystyrene beads. The porous beads and granular inert material comprise between 40% and about 75% of the bed by volume. The bead's presence exerts a buoyant effect which prevents bed packing and promotes desirable flow patterns with no observable channelling. This helps to minimize the formation of undesired or undesirable carbohydrates such as psicose.

    摘要： Levulose-bearing syrups are produced by passing a dextrose solution through a column or bed of an immobilized dextrose isomerase enzyme preparation. The useful life of the enzyme preparation is extended by conducting the isomerization initially at a low operating temperature, then increasing the temperature of operation after an initial decrease in enzyme activity has been observed. Also disclosed is an improved immobilized xylose isomerase enzyme preparation which is prepared by contacting a solution of xylose isomerase with particulate basic magnesium carbonate. The novel immobilized enzyme preparation is useful in enzymatically isomerizing dextrose solutions to levulose-bearing syrups.
