Kinetics of riboflavin production by Brewers' yeasts
Tamer, I.M.; Özilgen , Mustafa; Ungan, Suat (Elsevier BV, 1988-12)
The kinetics of riboflavin production by Saccharomyces cerevisiae and Saccharomyces carlsbergensis in synthetic media and wort were studied. The results indicated that riboflavin was produced by growing cells only. Riboflavin production rate was proportional to growth rate of the yeasts in the exponential phase. Riboflavin was depleted in the stationary phase. The depletion rate was expressed with a first-order kinetic expression in yeast concentration. The kinetics of substrate utilization and ethanol prod...
Kinetics of hydrogen generation from hydrolysis of sodium borohydride on Pt/C catalyst in a flow reactor
Boran, Asli; Erkan, Serdar; Özkar, Saim; Eroglu, Inci (Wiley, 2013-04-01)
Here, we report the results of a kinetic study on the hydrogen generation from the catalytic hydrolysis of sodium borohydride in a differential flow reactor. As catalyst platinum supported on carbon (Pt/C) was used in two forms: either as powder or coated on carbon cloth. For optimization of the system several parameters such as sodium hydroxide concentration, sodium borohydride concentration and the flow rate of the feed solution were varied. It was found that the H2 generation rate increases with an incre...
Kinetics of biological hydrogen production by the photosynthetic bacterium Rhodobacter sphaeroides O.U. 001
Koku, Harun; Gündüz, Ufuk; Türker, Lemi (2003-04-01)
The kinetics and the effects of various parameters on hydrogen production by Rhodobacter sphaeroides O.U. 001 were investigated in a batch column photobioreactor. In particular, the effect of the inoculum age and the implementation of a light-dark cycle illumination scheme for emulating natural sunlight have been investigated in detail. The possibility of using yeast extract to replace the rather expensive vitamin mixture in the medium was also studied. The results show that hydrogen production is decrease...
Kinetics of amino acid production by over-producer mutant microorganisms
Özilgen, Mustafa (Elsevier BV, 1988-2)
Experimental data were modeled based on the literature for the production of nine different amino acids by ten different mutant over-producer microorganisms. Mathematical modeling helped to better understand common aspects of these fermentations, which were not stressed previously by plotting the data only. A Luedeking-Piret type of a model was found to be valid for representing all the amino acid production data. This result indicated the similarity among the amino acid production patterns of all the mutan...
