| Kluyveromyces marxianus KD-15, called flex yeast, is a strain that is insensitive to catabolite repression and has the capacity to produce ethanol efficiently from a mixture of beet molasses and whey powder. When a fermentation test was conducted in 50 mL of a medium containing 200 mg mL-1 of sugar as sugar beet thick juice diluted with an arbitrary amount of crude whey, strain KD-15 produced over 99 mg mL-1 ethanol in all the media tested, and ethanol formation decreased in proportion to the volume of whey by K. marxianus NBRC 1963, the parental strain of KD-15, and Saccharomyces cerevisiae NBRC 0224, the reference strain for conventional ethanol production. Fermentation of thick juice diluted with whey alone by strain KD-15 at 30 °C initially proceeded... |
