Natural immobilisation of microorganisms for continuous ethanol production
Baptista, C. M. S. G.; Cóias, J. M. A.; Oliveira, A. C. M.; Oliveira, N. M. C.; Rocha, J. M. S.; Dempsey, M. J.; Lannigan, K. C.; Benson, P. S.Using a growth medium based on cane blackstrap molasses, we compared ethanol production by two strains of Saccharomyces cerevisiae that were immobilized in polyurethane foam cubes in a fluidised-bed fermenter. One strain (NCYC 1119) was adhesive and extremely flocculent, whilst the other strain was not adhesive and only weakly flocculent. The strong flocs of NCYC 1119 caused blockage of the bed, so that stable ...
