Identification of missing genes or proteins participating in the metabolic pathways as enzymes are of great interest. One such class of pathway is involved in the eugenol to vanillin bioconversion. Our goal is to develop an integral approach for identifying the topology of a reference or known pathway in other organism. We successfully identify the missing enzymes and then reconstruct the vanil...

Wild fruiting bodies of medicinal mushroom Antrodia camphorata are only found on the endemic species bull camphor tree, Cinnamomum kanehirae, in Taiwan. Despite the evident importance of the host components in promoting the growth of A. camphorata, insights into the underlying mechanisms are still lacking. Here, we first evaluated effects of the compounds from C. kanehirai, C. camphora, and A. ...

The electrochemical detection of interactions between aptamers and low-molecular-weight targets often lacks sensitivity. Signal amplification improves the detection of the aptamer-analyte complex; Bsm DNA polymerase was used to amplify the signal from the interaction of vanillin and its aptamer named Van_74 on an ion-sensitive field-effect transistor (ISFET)-based biosensor. The aptamer was imm...

It may be possible to exploit olfactory attachments shown by chickens, Gallus gallus domesticus, to improve their welfare. In the present study, chicks were housed in groups of 15 in wooden boxes from 1 day of age. Experiment 1 compared fear responses in pairs of 8–10-day-old chicks with no previous experience of vanillin when they were exposed to an unfamiliar open field containing a dish of f...

Phytophenols such as para-substituted 2-methoxyphenols exhibit antioxidant and anti-inflammatory activities, however, their biological activities are concentration-dependent, possibly due to their dual property of being both antioxidant and prooxidant. Eugenol (2-allyl-2-methoxyphenol) and isoeugenol (4-propenyl-2-methoxyphenol) did not reveal cyclooxygenase-2 (COX-2)-inhibiting activity in mac...

Volatile oils extracted by steam distillation from four plant species turmeric (Curcuma longa), kaffir lime (Citrus hystrix), citronella grass (Cymbopogon winterianus) and hairy basil (Ocimum americanum)), were evaluated in mosquito cages and in a large room for their repellency effects against three mosquito vectors, Aedes aegypti, Anopheles dirus and Culex quinquefasciatus. The oils from turm...

the effect of vanillin on the corrosion behavior of aa6061 al alloy in 3.5% nacl solution wasinvestigated using potentiodynamic polarization and electrochemical noise (en) techniques. vanillinoffers interesting possibilities for corrosion inhibition due to its nontoxicity and high solubility inaqueous media. the best inhibition effect at 200 ppm vanillin was a marked characteristic of theinhibi...

Vanillin ― a bioactive substance to interfere various biological activities is reportedly able mitigate fouling in membrane bioreactor (MBR). However, impact of continuous dose vanillin on treatment performance and microbial MBR are still unknown. In this study, effects production extracellular polymeric substances (EPS) community was investigated lab-scale under vanillin. remarkably reduced ac...
