Range of products and illustration of the key research problems associated with cell factory design and development. a Biotech products range from high-value-added to low-value-added products, with the latter being produced in large quantities and the former in small quantities. Examples of the different types of products are indicated. The yeast S. cerevisiae is used for the production of products in the whole spectrum. b In connection with the development of yeast for the production of different types of products using different sugars as feedstock, there is a need for an extensive platform of technologies from synthetic and systems biology
