Ethanol production by immobilized Saccharomyces cerevisiae, Saccharomyces uvarum, and Zymomonas mobilis
TL;DR: The development of a multiple disk shaft eliminated the problem both of uneven distribution of alginate‐encapsulated cells and of glucose channeling within the continuous‐flow fermentor column and improved alcohol production about threefold for the yeast cells.

Continuous conversion of D-xylose to ethanol by immobilized pachysolen tannophilus
TL;DR: The yeast Pachysolen tannophilus was entrapped in calcium alginate beads to ferment D‐xylose on a continous basis in the presence of high cell densities and productivity increased with the mass of cells immobilized, indicating that only 40% of the entrapping biomass was effective in converting D‐ xylose to ethanol because of diffusion limitations.

Continuous and static fermentation of glucose to ethanol by immobilized Saccharomyces cerevisiae cells of different ages
TL;DR: In most cases, the continuous fermentations were better than the static ones in producing maximum ethanol yields over extended time periods, and older yeast cells were more efficient than younger ones.

Hydrolysis of raffinose in a hollow‐fiber reactor using an unrefined mixture of α‐galactosidase and invertase
TL;DR: It was found empirically that In (C/C0) was linear in Q−1, with the absolute value of the slope decreasing with increasing C0, and the linearity of such plots were predicted by Lewis and Middleman from Waterland et al. for a single enzyme system obeying first‐order kinetics.

Continuous bioconversion of starch to ethanol by calcium-alginate immobilized enzymes and yeasts
TL;DR: In this paper, a continuous bioconversion of starch to EtOH by immobilized enzymes and yeasts was studied, in either 2-stage or single-stage (simultaneous) operations.
