Geraniol (a, b) and nerol (c, d) were added to BY4741 culture (a, c) or medium without yeast inoculation (b, d). The highest peak corresponding to nerol was detected in the chromatogram of extract from BY4741 culture, in which nerol was added as a substrate (Figure1c). Although geranic acid and citronellic acid were detected in the chromatogram of geraniol-added medium, their peaks were much smaller than those detected in geraniol-added BY4741 culture (Figure1a and b).
