Non-conventional yeast Metschnikowia pulcherrima and its application in biotechnology

Metschnikowia spp. are extensively studied “non-conventional” yeasts. Strains belonging to these genera are considered as non-pathogenic and safe. The unique properties of Metschnikowia spp. allow us to look at these microorganisms as a promising subject for evolutionary genetics, taxonomy, ecology, as well as a natural biocontrol agent in biotechnology. This article provides a synthesis of the systematics, morphology, ecology and physiology of Metschnikowia spp., with special attention to M. pulcherrima . These yeasts are able to produce a number of important metabolites, including organic acids, aroma compounds, oil or pulcherrimic acid. In addition, this review discusses possible applications of these non-conventional yeasts in biotechnology. 1. Introduction. 2. Taxonomy. 3. Ecology. 4. Morphology and physiology. 5. Parasexual cycle. 6. Metschnikowia pulcherrima – biochemical activity and application potential. 7. Summary
