This work demonstrated the technological feasibility of the three‐phase airlift bioreactor (ALR) with brewing yeast immobilized on spent grains (a brewing by‐product) for continuous beer production. The optimum fermentation performance of the one stage immobilized cell bioreactor was achieved at residence times between 18–25 h (dilution rate 0.04–0.055 h?1) and was characterized by an apparent degree of attenuation in the range of 70–80%. The productivity of the system in terms of ethanol concentration in green beer (ca. 4.2%) was satisfactory. Although the diacetyl concentration in the young beer was high (0.32 mg L?1 at D = 0.04 h?1) it is speculated that the level could be reduced by cell growth control, aeration and temperature optimisation. The immobilized yeast fermentation in the ALR was shown to be robust in recovery after process upsets. 相似文献

固定化酵母在(糖蜜)酒精连续发酵生产中的应用 总被引:1,自引:2,他引:1
固定化酵母替代传统工艺,应用于糖蜜酒精连续发酵生产中,采用两级连续发酵工艺,1#罐为酵母罐,2#罐为发酵罐,经6个月使用,结果表明,固定化酵母发酵能力强,但6个月后,随成熟醪酸度上升,成品酒精质量受到影响。如何抑制杂菌亦尚待进一步研究。 相似文献
