Abstract

Bioaromas can be produced by lipases either through their hydrolytic or (trans)esterifying activities. Therefore, this work reports the development of a lipase-catalyzed biotransformed licuri oil, forming volatile ethyl esters with odor notes resembling tropical fruits. Ethyl octanoate formation was promoted when 7.0 % (m/v) Lipozyme 435® was used to convert a grain alcohol:licuri oil mixture (51:49, v/v) at 58ºC and 70 rpm for 6 hours. The biotransformed oil has shown antimicrobial activity against Staphylococcus hominis, S. epidermidis, and Corynebacterium xerosis, bacteria associated with bad skin odor. Finally, this biotransformed oil was used without further treatments (e.g., recovery or purification procedures) to prepare two cosmetic formulations (in a dosage of 1.5 %), aiming for both fragrant and deodorant activity.

以脂肪酶为介导的醇解技术,用于在地衣油中原位生产酯类生物芳香物质,并将其应用于化妆品中。
脂肪酶可通过水解或(反式)酯化活性产生生物芳香。因此,本研究报告开发了一种在脂肪酶催化下生物转化的地衣油,可形成挥发性乙酯,具有类似热带水果的气味。当使用 7.0%(m/v)的 Lipozyme 435® 在 58ºC 和 70rpm 的条件下转化谷物酒精:地衣油混合物(51:49, v/v)6 小时后,辛酸乙酯的形成得到了促进。生物转化油对与皮肤异味有关的葡萄球菌、表皮葡萄球菌和干燥杆菌具有抗菌活性。最后,这种生物转化油未经进一步处理(如回收或提纯程序)就被用于制备两种化妆品配方(用量为 1.5%),目的是同时具有芳香和除臭活性。

期刊介绍: The Journal of Biotechnology has an open access mirror journal, the Journal of Biotechnology: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal provides a medium for the rapid publication of both full-length articles and short communications on novel and innovative aspects of biotechnology. The Journal will accept papers ranging from genetic or molecular biological positions to those covering biochemical, chemical or bioprocess engineering aspects as well as computer application of new software concepts, provided that in each case the material is directly relevant to biotechnological systems. Papers presenting information of a multidisciplinary nature that would not be suitable for publication in a journal devoted to a single discipline, are particularly welcome.
