Yeast Diversity in Human Welfare
Giới thiệu về sách điện tử này
Yeasts are eukaryotic microfungi widely found in natural environments, including those with extreme conditions such as low temperatures, low oxygen levels and low water availability. To date, approximately 2,000 of the estimated 30,000 to 45,000 species of yeast on Earth, belonging to around 200 genera have been described. Although there are a few that are opportunistic human and animal pathogens, the vast majority of yeasts are beneficial, playing an important role in the food chain and in the carbon, nitrogen and sulphur cycles. In addition, yeasts such as Saccharomyces cerevisiae, Hansenula polymorpha and Pichia pastoris are used in expressing foreign genes to produce proteins of pharmaceutical interest.
A landmark in biotechnology was reached in 1996 with the completion of sequencing of the entire S.cerevisiae genome, and it has now become a central player in the development of an entirely new approach to biological research and synthetic biology. The sequencing of genomes of several yeasts including Schizosaccharomyces pombe, Candida albicans and Cryptococcus neofromans has also recently been completed.

After obtaining M.Sc. and Ph.D. at the University of Saugar (India) T. Satyanarayana had post-doctoral stints at the Paul Sabatier University and National Institute of Applied Sciences, Toulouse, France. In 1988, he joined the Department of Microbiology, University of Delhi South Campus as Associate Professor and became Professor in 1998. His research efforts have been focused on understanding the diversity of yeasts, and thermophilic fungi and bacteria, their enzymes and potential applications, heterotrophic carbon sequestration and metagenomics. He has published over 250 scientific papers and reviews and edited six books. He has two Indian patents to his credit. He has been conferred with Dr. G.B. Manjrekar award of the Association of Microbiologists of India in 2004, Dr. V.S. Agnihotrudu award of Mycological Society of India in 2009 and Malaviya award of Biotech Research Society of India in 2012 for his distinguished contributions.
Gotthard Kunze studied biology at the Ernst Moritz Arndt University in Greifswald. He got a post-doctoral fellowship and a position as scientific assistant at the Department of Biology of the University. In 1986 he joined as a research associate at the Institute of Plant Genetics and Crop Plant Research (IPK), Gatersleben. Since 1998 he has been a Visiting Professor at the University of Greifswald and Professor at the Technical University Anhalt at Köthen since 1998. During this period, he focused his research activities on yeast genetics (construction of new yeast host vector systems, heterologous gene expression, thermo- and osmo-resistance in non-conventional yeasts and microbial yeast biosensors). Prof. Gotthard Kunze is the author of about 182 publications, editor of two books and teaches at the universities of Greifswald and Köthen.
