Based on the feedback of his very successful monograph Yeast, Martin Feldmann devised a comprehensive, student friendly textbook on yeast biology. The scope has been expanded; the cell and molecular biology sections have been drastically expanded and reach now the level of a stand-alone all-inclusive textbook; alongside information on other yeast species and the biotechnology of yeast has been added with contributions from additional authors. Given the tremendous importance of yeast biology in almost all areas of modern biology this textbook is long overdue and caters to need of an increasing number of students in biomedical research, cell- and molecular biology, microbiology and biotechnology.
