Preface

Yeasts are eukaryotic microbes placed in the kingdom Fungi, under the phyla Ascomycota and Basidiomycota with approximately 2000 species described till date. These are estimated to constitute 1–1.5% of the fungal species described, and the number of existing yeast species is expected to exceed that of the described ones. In case yeasts make up 1–1.5% of the estimated fungal species extant on Earth of three million species, the yeast species would be between 30,000 and 45,000. Extensive efforts are needed to understand the diversity of yet to be cultured yeast species. Yeasts are mostly unicellular, although some species develop multicellular characteristics by forming pseudohyphae. Most yeasts reproduce asexually by mitosis, and many do so by the asymmetric division process called budding and a few by fission. By fermentation, the yeast species Saccharomyces cerevisiae and others have been converting carbohydrates to carbon dioxide and
