This study lays great emphasis on establishing a reliable analytical platform to quantify and specify volatile fatty acids (VFAs) in the aqueous phase by derivatizing VFAs into their corresponding alkyl esters via thermally-induced rapid esterification (only 10 s reaction time). To

In this study, it is introduced a sustainable synthetic route of alkyl esters, considered value-added industrial chemicals and fuels, from volatile fatty acids (VFAs) that can potentially be generated from organic waste. In the presence of a porous carbon material

The isovaleric acid-emanating silkworm mutant skunk (sku) was first studied over 30 years ago because of its unusual odour and prepupal lethality. Here, we report the identification and characterization of the gene responsible for the sku mutant. Because of its specific
