A systematic and powerful knowledge-based framework exists for improving the activity and stability of chemical catalysts and for empowering the commercialization of respective processes. In contrast, corresponding biotechnological processes are still scarce and characterized by case-by-case development strategies. A systematic understanding of parameters affecting biocatalyst efficiency, that is, biocatalyst activity and stability, is essential for a rational generation of improved biocatalysts. Today, systematic approaches only exist for increasing the activity of whole-cell biocatalysts. They are still largely missing for whole-cell biocatalyst stability. In this review, we structure factors affecting biocatalyst stability and summarize existing, yet not completely exploited strategies to overcome respective limitations. The factors and mechanisms related to biocatalyst destabilization are discussed and demonstrated inter alia based on two case studies. The factors are similar for processes with different objectives regarding target molecule or metabolic pathway complexity and process scale, but are in turn highly interdependent. This review provides a systematic for the stabilization of whole-cell biocatalysts. In combination with our knowledge on strategies to improve biocatalyst activity, this paves the way for the rational design of superior recombinant whole-cell biocatalysts, which can then be employed in economically and ecologically competitive and sustainable bioprocesses.
