- ... Respiratory and fermentative pathways coexist to support growth and product formation in Pichia stipitis. This yeast grows rapidly without ethanol production under fully aerobic conditions, and it ferments glucose or xylose under oxygen-limited conditions, but it stops growing within one generation under anaerobic conditions. Expression of Saccharomyces cerevisiae URA1 (ScURA1) in P. stipitis enab ...

- ... Viable Saccharomyces cerevisiae and Candida shehatae cells were co-immobilized in a composite agar layer/microporous membrane structure. This immobilized-cell structure was placed in a vertical position between the two halves of a double-chambered, stainless-steel bioreactor of original design and applied to the continuous alcoholic fermentation of a mixture of glucose (35 g dm(-3)) and xylose (15 ...
