Sažetak

Prethodna istraživanja, koja su se bavila simulacijom P. shermanii suspenzije nastavljena su i u ovom radu prime-njena na suspenziji Saccharomyces cerevisia. Dobijeni rezultati ukazuju da je moguće značajno uvećanje zapreminskog koeficijenta prenosa mase kιa u prisustvu n-dodekana kao "kiseoničnog vektora", ali se intenzitet uvećanja mora korelisati sa karakteristikama biomase, posebno njenom hidrofobnošću. Zbog velikog afiniteta ćelija kvasca ka kapima ugljovodonika, povećanje prenosa mase kiseonika je nešto manje nego što je zabeleženo u slučaju simulacionih fermentacionih medijuma ili suspenzija bakterija.

Ključne reči

bioreaktor sa mešanjem; kiseonični vektor; n-dodekan; S. cerevisiae; kvasci; koeficijent prenosa mase kiseonika; aeracija; površinska aeracija
