Reflections on the classification of yeasts for different endusers in biotechnology, ecology, and medicine Authors Ann Vaughan-Martini Dipartimento di Biologia Vegetale e Biotecnologie Agroambientali, Università di Perugia, Sez. Microbiologia Applicata e Collezione dei Lieviti Industriali DBVPG, Perugia, Italy Keywords: yeast identification, identification, yeast biotechnology, conventional and molecular taxonomy Abstract The approach to yeast identification has significantly changed in just a few decades due to the rapid increase in basic biological knowledge, increased interest in the practical applications and biodiversity of this important microbial group, and enormous technological advances. While some conventional methods can still be validly applied, many molecular techniques have been developed that allow for strain classification on all taxonomic levels. A critical evaluation of the actual scope of each identification procedure will in the end determine the most appropriate use of the many protocols now available. Nonetheless, the oldest tool of microbiology, the microscope, is still a fundamental accessory for studies involving yeast biology, biodiversity and taxonomy.
