Fructanase and fructosyltransferase are interesting for the tequila process and prebiotics production (functional food industry). In this study, one hundred thirty non-Saccharomyces yeasts isolated from "Mezcal de Oaxaca" were screened for fructanase and fructosyltransferase activity. On solid medium, fifty isolates grew on Agave tequilana fructans (ATF), inulin or levan. In liquid media, inulin and ATF induced fructanase activities of between 0.02 and 0.27U/ml depending of yeast isolate. High fructanase activity on sucrose was observed for Kluyveromyces marxianus and Torulaspora delbrueckii, while the highest fructanase activity on inulin and ATF was observed for Issatchenkia orientalis, Cryptococcus albidus, and Candida apicola. Zygosaccharomyces bisporus and Candida boidinii had a high hydrolytic activity on levan. Sixteen yeasts belonging to K. marxianus, T. delbrueckii and C. apicola species were positive for fructosyltransferase activity. Mezcal microbiota proved to showed to be a source for new fructanase and fructosyltransferases with potential application in the tequila and food industry.
果聚糖酶和果聚糖转移酶在龙舌兰酒生产(功能性食品工业)和前体生产中很有趣。在这项研究中,从“瓦哈卡梅斯卡尔”中分离出的 130 株非酿酒酵母被筛选出具有果聚糖酶和果聚糖转移酶活性。在固体培养基上,50 株分离物在龙舌兰果糖(ATF)、菊粉或蔗聚糖上生长。在液体培养基中,根据酵母分离株的不同,菊粉和 ATF 诱导的果聚糖酶活性在 0.02 到 0.27U/ml 之间。马克斯克鲁维酵母和德巴利酵母对蔗糖表现出高果聚糖酶活性,而东方伊萨酵母、白假丝酵母和蜜环菌对菊粉和 ATF 的果聚糖酶活性最高。毕赤酵母和博伊丁假丝酵母对蔗聚糖具有很高的水解活性。属于马克斯克鲁维酵母、德巴利酵母和蜜环菌的 16 株酵母具有果聚糖转移酶活性。梅斯卡尔微生物群被证明是一种新的果聚糖酶和果聚糖转移酶的来源,具有在龙舌兰酒和食品工业中的潜在应用。
