Feasibility of continuous main fermentation of beer using immobilized yeast
Fermentation is the most time consuming step in the production of beer and therefore the effective use of fermentation vessels is a crucial element in brewing economy. One means of increasing the productivity of a batch process is to convert it to a continuous one. Experiments in continuous fermentation emerged during the 1950s and 1960s, but by the end of 1970s most of them had been closed dow...
متن کاملImmobilized yeast bioreactor systems for continuous beer fermentation
Two different types of immobilized yeast bioreactors were examined for continuous fermentation of high-gravity worts. One of these is a fluidized bed reactor (FBR) that employs porous glass beads for yeast immobilization. The second system is a loop reactor containing a porous silicon carbide cartridge (SCCR) for immobilizing the yeast cells. Although there was some residual fermentable sugar i...
متن کاملContinuous beer fermentation using immobilized yeast cell bioreactor systems.
Traditional beer fermentation and maturation processes use open fermentation and lager tanks. Although these vessels had previously been considered indispensable, during the past decades they were in many breweries replaced by large production units (cylindroconical tanks). These have proved to be successful, both providing operating advantages and ensuring the quality of the final beer. Anothe...
متن کاملCholine Kinase from Brewers’ Yeast
Choline kinase was purified approximately 300-fold, in 5% yield, from an autolysate of dried brewers’ yeast. A molecular weight of 67,000 was estimated using a Stokes radius of 33 A, as determined by Sephadex G-200 chromatography. An s~,,,~ of 4.8 S was obtained by sucrose density gradient centrifugation. Enzyme activity was diminished by sulfhydryl inhibitors and stabilized by the presence of ...
متن کاملAdaptive Control of Continuous Fermentation with Immobilized Yeasts Saccharomyces Cerevisiae
In this paper, a new approach for adaptive linearizing control of continuous fermentations with immobilized yeasts Saccharomyces cerevisiae BO 213 was proposed. Three fermentations with three different procedures of cells immobilization were investigated. The switching from batch to continuous mode of cultivation was realized automatically in time when the ethanol production rate reaches its ma...
