The wine and beer yeast Dekkera bruxellensis
Recently, the non-conventional yeast Dekkera bruxellensis has been gaining more and more attention in the food industry and academic research. This yeast species is a distant relative of Saccharomyces cerevisiae and is especially known for two important characteristics: on the one hand, it is considered to be one of the main spoilage organisms in the wine and bioethanol industry; on the other h...
متن کاملCloning and Expression Gene in HD34 Beer Yeast
Alcohol Dehydrogenase (ADH) gene was isolated from Bacillus subtilis by PCR amplification. The 1.1kb amplified fragment was confirmed to be the ADH gene by DNA sequencing. The gene was inserted into expression plasmid pYC6/C7, transformation HD34 beer yeast, as well as some transformants with ADH activity were obtained. [Nature and Science, 2004,2(2):64-66]
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 کاملFeasibility 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 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...
