“…The present experimental limit on the + → e + e − e + decay branching ratio [30] is B < 1 × 10 −12 at 90% C.L., obtained by the SINDRUM experiment [31] in 1988. Since then, no other experimental searches have been proposed so the SINDRUM experiment has to be taken as reference.…”

“…These problems have made the aerobic growth of S. cerevisiae on glucose to continue to be of research interest (Alexandra, 1990;Kristiansen, 1994;Petrik et al, 1983;Rieger et al, 1981Rieger et al, , 1983Sonnleither and Kappeli, 1986). In order to achieve a maximum yield at the highest possible productivity, a well designed feeding strategy for S. cerevisiae is needed (Belgardt 2000;Ejiofor et al, 1994a,b). The dilution rate and the respiratory quotient (RQ) can be used as control in overcoming the problems encountered during baker's yeast production.…”

Data collected during high-cell-density cultivation of Saccharomyces cerevisiae DSM 2155 on glucose in a simulated five-phase feeding strategy of fed-batch process, executed on the Universal BIoprocess CONtrol (UBICON) system using 150L bioreactor over a period of 24h have been analysed. The consistency of the data set was checked using both the available electron and carbon balances. Estimates of the true energetic yields and cell maintenance requirements were obtained through the application of a multivariate statistical procedure known as covariate adjustment technique. A low value of maintenance coefficient, m e = 0.004h -1 , and a high average value of the true biomass energetic yield, h max = 0.745, were obtained for the bioreactor system, which showed that the organism was in no danger of ethanol produced during this cultivation. A simple model for estimating the distribution of substrate consumed between the fermentative and the respiratory pathways in the oxido-reductive process was developed based on the respiratory quotient (RQ) values. The fraction of substrate consumed for respiratory metabolic activities (q sresp /q s ) was virtually 1.0 for the first three phases of the feeding strategy, which accounted for the first sixteen hours of the 24h operation. This was an indication that ethanol formation was avoided during this period.

This paper presents an integrated model describing the control of Saccharomyces cerevisiae yeast cells bioenergetics. This model describes the oxidative and respirofermentative metabolism. The model assumes that the mitochondria of the Saccharomyces cerevisiae cells are charged with NADH during the tricarboxylic acid cycle, and NADH is discharged from mitochondria later in the electron transport system. Selected effects observed in the Saccharomyces cerevisiae eucaryotic cells, including the Pasteur's and Crabtree effects, are also modeled.
