CONTINUOUS ANAEROBIC ETANOLIC FERMENTATIO N WITH A STRAIN OF SACCHAROMYCES-CEREVISIAE ALCOHOL RESISTANT

Continuous ethanolic fermentation in strictly anaerobic conditions of 200 g/L glucose solutions by Saccharomyces cerevisiae FDH1 is studied. FDH1 is a genetic hibrid alcohol resistant strain. The fermentor is o perated at 30-degrees-C and pH, 3.4, and the influence of dilution rat e on productivity is graphically determinated. The maximum productivit y, 2.4 g/L.h, is achieved at a dilution rate of approximately 0.030 h- 1. This value is also analiticaly verified. The continuous fermentatio n is analiticaly studied and the results are compared with the obtaine d by other authors.
