Abstract
Cilj ovog doktorskog rada bio je usporediti ekstrakciju i istiskivanje plinom (eng. gas stripping) kao metode izdvajanja etanola iz fermentirane podloge. Posebno je istraženo toksično djelovanje ekstraktanata di(propilenglikol)butiletera, 1-tert-butoksipropan-2-ola, etil-oleata, oktan-1-ola i oleil alkohola na kulturu kvasca Saccharomyces cerevisiae te je raspravljena njihova moguća primjena u integriranom sustavu. Provedeno je istraživanje razdvajanja faza i stabilnosti emulzija za sustave podloga-ekstraktant. Najpogodniji plin za istiskivanje etanola izabran je temeljem rezultata istraživanja različitih plinova (zrak, dušik i ugljikov(IV) oksid) obzirom na brzinu izdvajanja etanola iz razrijeđenih vodenih otopina pri različitim prividnim srednjim linearnim brzinama strujanja plina. Istiskivanje etanola iz fermentirane podloge i iz organskog ekstrakta pomoću CO2 istraženo je pri atmosferskom tlaku i u uvjetima sniženog tlaka.
Abstract (english)
The aim of this investigation was the comparison of extraction and stripping as methods of ethanol separation from fermentation broth. The toxicity of octan-1-ol, 1-tert-butoxy-propan-2-ol, di(propylene glycol) butyl ether, ethyl oleate and oleyl alcohol on the culture of the yeast Saccharomyces cerevisiae was studied. The use of examined solvents in an integrated system was discussed. The phase separation and the emulsion stability for the broth-extracting solvent system were examined. The most convenient gas for the ethanol stripping was selected by examining of different gases (air, nitrogen and carbon(IV) oxide) concerning of ethanol stripping rate (from diluted aqueous solutions) and different superficial gas velocities. Gas stripping of ethanol by CO2 as a carrier from fermented broth and organic extracts was studied under atmospheric and low-pressure conditions.
