Twenty-five Saccharomyces cerevisiae strains were screened for the highest sugar tolerance, ethanol-tolerance, ethanol production, and inhibitor resistance, and S. cerevisiae KL5 was selected as the best strain. Inhibitor cocktail (100%) was composed of 75 mM formic acid, 75 mM acetic acid, 30 mM furfural, 30 mM hydroxymethyl furfural (HMF), and 2.7 mM vanillin. The cells of strain KL5 were tre...

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...

As one of the most abundant materials in nature, lignin has been used widely in co-generation operations and for fine chemicals and bio-fuels production. These uses, although important, are of relatively low value. Lignin contains many aromatic compounds with useful structures, and it is potentially more profitable to produce high-value fine chemicals from the low-molecular weight lignin fracti...

Synthetic biology approaches achieving the reconstruction of specific plant natural product biosynthetic pathways in dedicated microbial "chassis" have provided access to important industrial compounds (e.g., artemisinin, resveratrol, vanillin). However, the potential of such production systems to facilitate elucidation of plant biosynthetic pathways has been underexplored. Here we report on th...

Sugar maple hemicellulosic hydrolysate was utilized as a renewable feedstock for polyhydroxyalkanoates production by Burkholderia cepacia ATCC 17759. To estimate inhibitory effects of the hydrolysate, response surface methodology was utilized to analyze cell growth and PHA accumulation in the presence of multiple inhibitors. Mixture design was employed to study the correlation between the propo...

The title compound (ethyl vanillin), C(9)H(10)O(3), an important food additive and flavouring agent approved by FAO/WHO, has a vanilla odor four times that of vanillin and shows anti--mutagenic activity. There are two mol-ecules in the asymmetric unit, each having a planar conformation and an intramolecular O-H⋯O bond. Mol-ecules are connected side-by-side, building infinite ribbons along cvia ...

The control of biofouling is required to improve membranes performances for water filtration. In this context, developing bioinspired approaches modify and give them antifouling properties an interesting alternative. study, we elaborated new anti-biofouling by coating with vanillin, a natural bioactive molecule acting as Quorum Sensing Inhibitor (QSI). First, the adsorption vanillin filtration ...
