It has a darker color and fresher scent similar to lemon and lemon essential oil. When the oxidation steps of geraniol to the carboxylic acids in BY4741 and NCYC 1681 are considered, changes of the redox state in the yeast cells may determine whether citronellal, an intermediate metabolite of citronellol production (Steyer etal. These data indicate that conversions of geraniol to citronellol, geranic acid, and citronellic acid are mainly catalyzed by S. cerevisiae enzymes whereas conversion of geraniol to linalool proceeds nonenzymatically (Figure2). Citronella grass, Cymbopogon nardus, is a plant originated from Sri Lanka and India (Mahalwal and Mahalwal and Ali, 2003) that has shown antibacterial and antioxidant properties in vitro being widely used in teas for its soothing properties (Castro et al., 2010; Park et al., 2015). Geraniol candles repelled mosquitoes and sandflies five times more effectively than citronella candles and two times more effectively than linalool candles. Deletion of alcohol dehydrogenase genes such as ADH4 in brewing yeasts may be effective in prevention of the loss or decrease of geraniol and citronellol without affecting growth and ethanol production. The Java type is similar and derived from a related species called Cymbopogon winterianus.
