A. consociatus and A. pohliae were originally classified in genus Alicyclobacillus, but were later reclassified into the novel genus Effusibacillus in 2014. Most Alicyclobacillus species optimally grow in the 40-55 °C range.

The specific activity of the control HRP enzyme was compared with the bioCNT-HRP complex, showing that the calculated specific activity of free HRP was ~ 1.46 μM/s (100%) and that of bioCNT-HRP was ~ 1.25 μM/s, which is approximately equal to 85% relative activity of the free enzyme concentration (Fig. 7A). An alternative method of synthesis involves treating guaiacol directly with an equimolar amount of glycerol α-monochlorohydrin in a strongly alkaline solution or suspension (Scheme 2). When the vigorous reaction subsides, the mixture is heated for three hours, concentrated in vacuo, and extracted with hot isopropanol to yield (after filtration and cooling) product in greater than 80% yield.

Quinary (Fifth) - guaiacol: FL/FR: para-alpha-dimethyl styrene : odor: Phenolic, spicy, styrene, eugenol and guaiacol-like with musty, coffee and nutty nuances : flavor: Spicy, balsamic, musty and eugenol / guaiacol-like with a nutty nuance Guaiacol and 4-methylguaiacol have been identified as primary contributors to the resulting “smoke impact”. While there is strong evidence that these compounds are mostly present in grape and juice as non-volatile forms, analysis of their free fraction has been used as a tool for screening grapes and assessing taints in wines. enzyme, the extract is mixed with H2 O + O2 and a compound commonly known as Guaiacol (2-methyoxyphenol). If the enzyme is present, the peroxide is quickly converted to water and oxygen, and the oxygen reacts with the Guaiacol to produce a brown product, oxidized Guaiacol.

Guaiacol is also present in wood smoke, as a product of pyrolysis of lignin. Guaiacol has been found in the urine of patients with neuroblastoma and pheochromocytoma. As shown in Scheme 1, guaiacol (2-methoxyphenol) is treated with sodium ethoxide to give a sodium salt which is quenched with an epoxyalkene. The final step involves the oxidation of the alkene to the diol using potassium permanganate [4 ]. Sign in to download full-size image. Scheme 1. Guaiacol is a flavor compound occurs naturally in tomatoes and wine that is matured in oak barrels.
