The Superiority of Yeast Secondary Metabolites, from Industrial applications, Biological activities to Pharmaceutical potential

Yeasts are eukaryotic microorganisms that are existing in a wide range of habitats, thanks to their ability to adapt even in extreme locations and conditions. Moreover, the unicellular nature of yeasts makes them better suited for deep liquid substrates or moist and uneven surfaces. Till now, about 1500 species of yeasts are described, and the genus Saccharomyces is the well-studied genus of all the yeasts in terms of physiology and genetics. In this review, we elucidate the role of yeasts as biotechnological tool and their current and potential applications. We also highlighted the features, and industrial application of some marine yeasts. Furthermore, describing rarely basidiomycetous yeast involved in different applications. Contributions of yeasts and their enzymes in food, industrial, and pharmaceuticals fields were also discussed. Finally, employment of yeasts in biotransformation process was show.
