Abstract
Commercial baker's yeast-a low-cost product with a low profit margin-requires complex fermentation techniques (large-scale, fed-batch fermentation) and is subject to strict quality safety regulations. Large amounts of molasses, ammonia, and vitamins, as well as air and water (liquid and steam) are necessary for the efficient industrial production of baker's yeast. The associated production costs are strongly correlated to the increasing and volatile market price for molasses. In this regard, producers mainly concentrate their efforts on the search for alternative sugar sources and the further improvement of bioprocess control and efficiency. As industrial baker's yeast production has been optimized over many decades, there is only little room left for such improvements. New, interesting trends regarding baker's yeast production have been recently drafted by different research groups and are reviewed in this paper. Subsequently, we combined these multidisciplinary advances in an innovative strategic concept and demonstrated how industrial baker's yeast biomanufacture can be turned into a powerful, zero-discharge multipurpose bioprocess. As a result, the redesigned bioprocess provides a large amount of district heat as well as key molecules such as invertase and betaine. It uses side streams from the food industry as carbon and nitrogen sources and strongly relies on state-ofthe-art membrane technology. The presented approach aims to show how industrial aerobic processes can be employed within a sustainable industrial environment.
