Production of ethanol was observed at 117.4 g/l (148.6 ml/l, for S. cerevisiae NBRC10217T) and 130.4 g/l (165.1 ml/l, for S. cerevisiae K7) levels, respectively ( Table 5). This data is based on duplicate fermentation tanks, and the highest value of ethanol concentration was found for S. cerevisiae K7 at a 145.6 g/l (184.3 ml/l) level.
