Though lower concentrations of geranic acid and citronellic acid were detected in NCYC 1681 culture compared to those in BY4741 culture, the citronellic acid concentration also increased from the 8th day to the 10th day markedly (Figure3b). Geraniol is a monoterpenoid and is a major component of rose oil and citronella oil [11].It also occurs in geranium (hence, its name), lemon, and other essential oils. Geraniol (a, b) and nerol (c, d) were added to BY4741 culture (a, c) or medium without yeast inoculation (b, d). Growth in YPD medium was also suppressed in the adh3 strain (Figure S4). Figure 5.10.

Genes encoding alcohol dehydrogenase were selected, and effects of gene deletion on concentrations of residual geraniol and produced geranic acid, citronellic acid, and citronellol after 10-d cultivation were investigated. Studies suggest geraniol also works as an effective pesticide against various types of even smaller critters (like the kind from your darkest nightmares you can only see with a microscope). Geraniol, like all terpenes, is an organic compound of carbon, hydrogen, and oxygen molecules. That means its a natural nontoxic mode of action against potentially harmful insects like mosquitoes. Protein preparations could convert geranyl diphosphate (GDP) to geraniol in in vitro assays, a process which could be blocked by inorganic phosphatase inhibitors, suggesting a two-step conversion of GDP to geraniol.

Geraniol is monoterpene alcohol that is a main ingredient of rose oil; it also is present in many other essential oils. To clarify the metabolic pathways from geraniol/nerol to geranic acid and from geraniol/nerol to citronellic acid, potential substrates for biosyntheses of geranic acid and citronellic acid were added to BY4741 culture. In fact, free radicals are associated with cancer, Parkinsons disease, Alzheimers disease, and more. This is precisely the reason that citronella is used to prevent both internal and external infections and why it can play a central role in a parasite cleanse.

Like all commercially sold products that are intended to be applied to human skin, the EPA requires proper precautionary labeling on some insect repellents containing citronella so people know how to safely use it. A Nudix hydrolase cDNA from Pelargonium glandular trichomes, dubbed PgNdx1, encoded a cytosolic protein capable of hydrolyzing GDP to GP with a KM of about 750 nm but is only weakly active towards farnesyl diphosphate. These were all isolated using fractional vacuum distillation and identified using GC-MS. Citronellal, citronellol, and geraniol were identified at 13.6 min, 16.6 min, and 18.2 min, respectively.
