use of seawater to perform bio‐processes is a sustainable alternative. In this work, we used marine yeasts from deep‐sub‐seafloor sediments grown in seawater as bio‐catalysts to perform the stereoselective reduction of different ketones, and the bio‐transformations were accomplished in seawater as well. Strains of Meyerozyma guilliermondii and Rhodotorula mucilaginosa were able to reduce different aromatic
发酵和生物转化中大量消耗淡水是许多生物过程可持续性的一个问题。使用海水进行生物过程是一种可持续的选择。在这项工作中,我们使用了海水中生长的深海底沉积物的海洋酵母作为生物催化剂来进行不同酮的立体选择性还原,并且在海水中也完成了生物转化。瓜叶肉单胞菌和粘液红假单胞菌的菌株能够以高摩尔转化率和中等至高对映选择性还原不同的芳族酮,在海水和淡水中进行的生物催化之间没有显着差异。最后,选择的海洋酵母被用于还原海水中的关键中间体,以合成具有药物作用的分子(去氧孕烯,炔诺孕酮,孕二烯,普拉克索)。
