That means its a natural nontoxic mode of action against potentially harmful insects like mosquitoes. All Rights Reserved. It is considered for these deletion strains that the oxidation to geranic acid and citronellic acid was suppressed and, instead of it, the metabolic flow from geraniol was directed to the reduction to citronellol. This means it effectively expels parasitic wormsand other internal parasites by either stunning or killing them without causing any damage to the host. Aside from keeping away bug bites, citronella can work as a natural skin care aid by killing off bacteria and fungus.

Plant Growth Regulation Considering the substrate specificities of Adh1p, Adh3p, and Sfa1p reported in the literatures and the growth restriction in YPD medium, the decrease in geraniol consumption observed in these deletion strains may be a side effect of the gene deletions in metabolisms or due to a smaller number of the catalyst in yeast culture. One of the most popular uses for citronella oil is cleansing and conditioning the hair and scalp. This effect on the CNS was also reported in citronellal-treated mice. at Utsunomiya University.
