Saccharomyces cerevisiae cells, Kluyveromyces marxianus cells, inulase, glucose oxidase, chloroplasts, and mitochondria were immobilized in calcium alginate gels. Ethanol production from glucose solutions by an immobilized preparation of S. cerevisiae was demonstrated over a total of twenty-three days, and the half-life of such a preparation was shown to be about ten days. Immobilized K. marxianus, inulase, and glucose oxidase preparations were used to demonstrate the porosity and retraining properties of calcium alginate gels. Calcium alginate-immobilized chloroplasts were shown to perform the Hill reaction. Some experiments with immobilized mitochondria are reported.

This penultimate part of the centenary series looks at E Matthews' paper on "The alginates in dentistry' and is reviewed by Mike Braden. In the paper, Matthews discussed the need to find a suitable alternative to certain dental materials such as agar agar when the main supplier of this, Japan, entered the Second World War.
