Characterization of a spontaneous flocculation mutant derived from Candida glabrata: A useful strain for bioethanol production

Abstract A spontaneous flocculation mutant (Cgflo1) was obtained from Candida glabrata . Flocculation of Cgflo1 was dependent on divalent cations such as Ca 2+ and Mg 2+ and was inhibited by galactose. Cgflo1 is believed to be a useful strain for bioethanol production based on its flocculation ability at higher temperatures.
