Natural Immobilisation of Microorganisms for Continuous Ethanol Production
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 fluidized 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...
متن کاملfaciliting lexical access for the fluent production of speech
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...

15 صفحه اولImmobilisation of yeasts for continuous fermentation
Continuous ethanol fermentation from cheap sugar cane molasses was studied. Two strains of Saccharomyces cerevisiae were used, one of them flocculent, in order to evaluate the performance of fluidized tubular reactors, with and without support for yeast immobilisation (polyurethane foam and expanded clay argilate granules were tested). In this heterogeneous continuous system, with three phases,...
متن کاملUse of Tower Reactors for Continuous Ethanol Production
The purpose of this work was to develop a continuous fermentation system operating with a tower reactor using some flocculent yeast strains isolated from an industrial process. The strain was an used in the trial of the proposed system, composed of two serial glass tower reactor. The effects of the following variables were studied on the yield and productivity of the system: total reducing suga...
