Sažetak
Rast Saccharomyces cerevisiae (PTCC 24860) na pretretiranoj melasi iz šećerne repe je optimizovan primenom statističkog pristupa. U cilju oslobađanja svih monomernih šećera, melasa je tretirana razblaženom kiselinom. Uticaj parametara procesa, kao što su: koncentracija šećera, izvor azota, pH i vreme inkubacije na rast ćelija je statistički procenjen pomoću softvera Design Expert i aplikacijom centralnog kompozitnog dizajna (CCD) i metode odzivne površine. Optimalni uslovi gajenja su bili: pH 5,3, vreme inkubacije 24 h i sastav podloge od 35 g redukujućih šećera, 1,5 g NH4Cl i 1 g ekstrakta kvasca po litri podloge. Pri optimalnim uslovima rasta ćelija i vremenu inkubacije 12 h ostvarena je maksimalna proizvodnja etanola od 14,87 g/L.
