C. Abate et al., ETHANOL-PRODUCTION BY A MIXED CULTURE OF FLOCCULANT STRAINS OF ZYMOMONAS-MOBILIS AND SACCHAROMYCES SP, Applied microbiology and biotechnology, 45(5), 1996, pp. 580-583
Pure and mixed cultures of Zymomonas mobilis and Saccharomyces sp. wer
e tested for the production of ethanol using sucrose as the carbon sou
rce. Both strains, isolated from spontaneously fermenting sugar-cane j
uice, are flocculent and alcohol-tolerant. The best results were obtai
ned using a mixed culture, with a yield of 0.5 g ethanol/g sugar consu
med and a volumetric productivity of 1.5 g ethanol l(-1) h(-1). No lev
an was produced even if a sucrose-based medium was used.
