Abstract

In this study, growth and flocculation potential of five different flocculent yeasts: Candida sphaerica OB10, Kluyveromyces marxianus OY11, Saccharomyces cerevisiae OGB1, Torulopsis stellate OGB3 and Candida kefyr OGB10 were investigated under electromagnetic condition in batch and fed batch cultivation systems. Candida sphaerica OB10 had optimum growth of 9.36 log cfu/mL under batch culture system followed by Saccharomyces cerevisiae OGB1 with 9.19 log cfu/mL and Kluyveromyces marxianus OY11 with growth of 7.72 log cfu/mL in fed-batch culture system; both without electromagnetic induction. Torulopsis stellata OGB3 under fed-batch system was 9.78 log cfu/mL after electromagnetic induction. Also, Candida kefyr OGB10 had an optimum growth of 10.14 log cfu/mL in fed-batch culture system. The results of the flocculation potential of the yeast isolates showed a reduction in flocculation potential in fed-batch culture system after electromagnetic induction as compared with fed batch system without electromagnetic induction while Candida sphaerica OB10, Kluyveromyces marxianus OY11, Torulopsis stellate OGB3 and Candida kefyr OGB10 had an increase in flocculation potential in batch culture system after electromagnetic induction. These results showed that the batch culture system which was steady and undisturbed was more important in yielding well coagulated and bottom settled cells in electromagnetically induced yeast fermentation systems when compared with the fed-batch system
