A simple defined medium for the production of ethanol by Zymononas mobilis in continuous culture is presented. Under comparable cultural conditions very similar fermentation kinetics were obtained using simple, complex and semi-synthetic rich media.
The biosynthesis of a thermogelable, extracellular homo-beta-(1 leads to 3)-glucan called "curdlan," has been studied in batch and continuous cultures of Alcaligenes faecalis var. myxogenes. Curdlan production is associated with the poststationary phase of a nitrogen-depleted, aerobic batch culture. Exopolymer is not detected in single-stage, carbon-limited… (More)
A two-stage continuous-stirred-tank-reactor (CSTR) system is used to achieve high final alcohol concentrations (>100 g/l) with Zymononas mobilis ATCC 29191. By employing continuous cell recycle on the second stage CSTR of a two-stage process a high overall volumetric productivity (18.13 g/l/h) is achieved together with >100 g/l effluent alcohol.
Beef heart cytochrome oxidase (EC 126.96.36.199) prepared in this laboratory consistently presents 10 Coomassie blue staining zones on SDS-polyacrylamide gel electrophoresis. At pH 7.0 only two of these polypeptides (III and VIa) are labelled by radioactive N-ethyl maleimide (NEM). The labelling of VIa is variable and correlates with activity of particular… (More)
