Abstract [en]

The impact of encapsulation on the anaerobic growth pattern of S. cerevisiae CBS 8066 in a defined synthetic medium over 20 consecutive batch cultivations was investigated. In this period, the ethanol yield increased from 0.43 to 0.46 g/g, while the biomass and glycerol yields decreased by 58 and 23%, respectively. The growth rate of the encapsulated cells in the first batch was 0.13 h-1, but decreased gradually to 0.01 h-1 within the 20 sequential batch cultivations. Total RNA content of these yeast cells decreased by 39% from 90.3 to 55 mg/g, while the total protein content decreased 24% from 460 to 350 mg/g. On the other hand, the stored carbohydrates, i.e. glycogen and trehalose content, increased by factors of 4 and 4.5 within 20 batch cultivations, respectively. Higher biomass concentrations inside capsules led to a lower glucose diffusion rate through the membrane, and volumetric mass transfer coefficient for glucose was drastically decreased from 6.28 to 1.24 (cm3/min) by continuing the experiments. Most of the encapsulated yeast existed in the form of single and non-budding cells after long-term application.
