Summary The possibility of using hydrogen-peroxide as an oxygen source in immobilized whole cell systems was investigated. The conversion of glycerol to dihydroxyacetone performed by Ca-alginate immobilized Gluconobacter oxydans was used as a model system. The influence of basic parameters, such as pH, temperature and concentration of hydrogen-peroxide, on the conversion are reported. Continuous production using a packed bed could be substantially improved by using hydrogen-peroxide as a source of oxygen. The productivity was increased almost twenty-fold in the reactor. However, hydrogen-peroxide also caused deactivation of the oxidizing of the cells.
