Changes in biological properties over several generations, induced by controlling short-term evolutionary processes in the laboratory through selective pressure and whole-genome re-sequencing, have been actively conducted for several yeasts, primarily using Saccharomyces cerevisiae. With the versatility of this technique and the urgent need for alternatives to petroleum-based strategies, ALE has emerged as a hot topic, leading to new studies exploring the biotechnological improvement of non-conventional yeast species. This review highlights the applicability of ALE as a powerful tool to enhance species features and improve performance in biotechnology, emphasizing the role of non-conventional yeast species in combination with genome editing approaches.
Changes in biological properties over several generations, induced by controlling short-term evolutionary processes in the laboratory through selective pressure, and whole-genome re-sequencing, help determine the genetic basis of microorganism's adaptive laboratory evolution (ALE). Due to the versatility of this technique and the imminent urgency for alternatives to petroleum-based strategies, ALE has been actively conducted for several yeasts, primarily using the conventional species Saccharomyces cerevisiae, but also non-conventional yeasts. As a hot topic at the moment since genetically modified organisms are a debatable subject and a global consensus on their employment has not yet been attained, a panoply of new studies employing ALE approaches have emerged and many different applications have been exploited in this context. In the present review, we gathered, for the first time, relevant studies showing the ALE of non-conventional yeast species towards their biotechnological improvement, cataloging them according to the aim of the study, and comparing them considering the species used, the outcome of the experiment, and the employed methodology. This review sheds light on the applicability of ALE as a powerful tool to enhance species features and improve their performance in biotechnology, with emphasis on the non-conventional yeast species, as an alternative or in combination with genome editing approaches.
