Introduction Controlled partial oxidation of natural products, such as terpenes, is one of the most important technologies to obtain cosmetic ingredients. For economic reasons, these processes mainly involve the use of molecular oxygen as the primary oxidant. Their success depends mostly on the use of a catalyst containing metal species in order to promote both the rate of reaction and the sele...

The aim of this study is to evaluate the potential of a novel yeast Williopsis saturnus var. mrakii NCYC 500 to produce fruity beer. Fermentation performance of W. mrakii and beer volatile composition were compared against that fermented with Saccharomyces cerevisiae Safale US-05. oBrix, sugar and pH differed significantly between the two types of beer. A total of 8 alcohols, 11 acids, 41 ester...
